Neither player saw any action for the Tigers this season at the big league level, in large part due to injury.  Hembree made only six appearances (pitching six innings) with Triple-A Toledo, after spending more than a month on the injured list — Toledo just activated him from the IL on Friday.  As for Rosenthal, he tossed three minor innings before undergoing elbow surgery in mid-June.

This elbow procedure is the latest in a series of injuries that has plagued Rosenthal’s career for well over five seasons.  Since the start of the 2018 campaign, Rosenthal has thrown only 39 innings in the majors, due to such varied injuries as a Tommy John surgery, thoracic outlet syndrome surgery, and a hip surgery.  The nature of this latest elbow surgery isn’t known, but it is fair to wonder if it could be one setback too many for Rosenthal, and whether or not he might be considering retirement at age 33.

Hembree signed a minors deal with the Rays during the offseason and pitched in one game for Tampa before being designated for assignment.  The 11-year veteran had enough service time to reject an outright assignment in favor of free agency, which led to his signing with the Tigers.  Best known for his seven seasons with the Red Sox from 2014-2020, Hembree has since pitched for a whopping seven different teams, appearing at the MLB level with all of those clubs except Detroit.

Rosenthal, 33, hasn’t pitched in the Majors since the 2020 season and has just 39 big league frames under his belt since the conclusion of the 2017 season. Injuries have derailed the career of the former Cardinals closer, who underwent Tommy John surgery in 2017 and thoracic outlet surgery in 2021. Rosenthal also had surgery to repair a torn labrum in his hip during the 2021 season.

A healthy Rosenthal has proven himself capable of being one of the sport’s top relievers. From 2012-15, he boasted a 2.66 ERA and 30.4% strikeout rate, twice reaching 45 saves in a season along the way. His 2019 return from that 2017 Tommy John procedure was a disaster, but Rosenthal pitched 23 2/3 innings of 1.90 ERA ball while punching out 41.8% of his opponents during the shortened 2020 season. This will now be Rosenthal’s third surgery of note since his last big league pitch, however. He pitched in just three minor league games with the Tigers this year before landing on the injured list.

Kreidler, 25, has appeared in 37 games for the Tigers dating back to 2022 but has just a .165/.220/.209 slash in 102 big league plate appearances. He’s slashed .253/.374/.466 with 18 home runs and 22 steals through 446 plate appearances at the Triple-A level in his career, however, and is regarded as an above-average defender who can handle multiple spots around the infield (third base, shortstop and second base). He’s currently in physical therapy following the surgery. A timetable for his return wasn’t provided.

The 30-year-old Del Pozo returned to the Tigers on a minor league deal this offseason. He’d previously pitched 5 1/3 frames as a Tiger back in 2021 and also spent the 2022 season in their Triple-A bullpen, pitching to a 3.88 ERA in 53 1/3 frames. Del Pozo, who’s allowed 20 runs in 18 1/3 big league innings but has a more palatable 4.23 ERA in four Triple-A campaigns, appeared in just six games this season before landing on the injured list. The timing of this surgery will shelve him until late in the 2024 season and potentially all the way into the 2025 season.

Palacios joined the Detroit organization on an offseason waiver claim from the division-rival Twins. The Tigers non-tendered him almost immediately but brought him back on a minor league contract. The righty-swinging infielder has played the year in Toledo but gotten out to a woeful start offensively. Over 152 trips to the plate, he was hitting .176/.232/.352 while striking out 31.2% of the time.

The 26-year-old had a far better showing with Minnesota’s Triple-A club last year. Palacios had hit .283/.341/.462 with 14 homers over 102 contests. That earned him his MLB debut — first as a COVID substitute, then as an official contract selection in early September. He hit .143/.184/.229 during his first 30 MLB contests. Detroit acquired minor league infielder Joe Rizzo from the Marlins this morning, ostensibly pushing Palacios out of the mix.

Fry, a left-hander, inked a minor league deal in February. He’d been trying to work back to the majors for the first time since 2021. Fry made seven appearances but landed on the minor league injured list with elbow inflammation at the end of April. He hasn’t pitched in six weeks. The 29-year-old has appeared in parts of five big league campaigns, all with the White Sox. He owns a career 5.04 ERA with a 27.3% strikeout rate and 14% walk percentage in 139 1/3 frames.

Additionally, Toledo announced that veteran reliever Trevor Rosenthal is beginning a rehab assignment at Low-A Lakeland. The right-hander signed a minor league pact on the heels of two consecutive seasons lost to injury. He pitched twice for Toledo before landing on the IL with a sprain in his throwing elbow. It now seems he’s in position to build back towards competitive game action.

The first comes five days before the start of the season. For players who pass on that initial opt-out, they have additional windows to explore the open market on both May 1 and June 1 if they’ve yet to secure a spot on the 40-man roster. The second of those dates spurred some roster movement this year. Chris Devenski, Jeff Hoffman and Billy Hamilton were all called up to keep them from testing the market. Chase Anderson and Gary Sánchez found MLB opportunities with other organizations after leaving the Reds and Giants, respectively.

As that third opt-out date nears, it’s worth checking in on a few players with opt-outs under the CBA (as well as one player whose minor league contract contained a June 1 opt-out provision).

• Red Sox C Jorge Alfaro

Alfaro is not an Article XX(B) free agent, as he hit the open market via non-tender from the Padres last fall. However, the minor league deal he signed with Boston reportedly afforded him opt-out chances on both June 1 and July 1.

There’s certainly an argument for the 29-year-old catcher to trigger that provision. Alfaro has had an excellent year with the Red Sox’s top affiliate in Worcester. Through 187 plate appearances, he’s hitting .320/.364/.523 and has connected on six home runs. His 4.8% walk rate is modest but he’s kept his strikeouts to a near-average 23% clip while hitting for power.

Alfaro has had an inconsistent big league career, flashing power potential and big arm strength but struggling with his plate discipline and receiving work. He’s a .256/.305/.396 hitter in over 1600 major league plate appearances.

The Red Sox have used Connor Wong and Reese McGuire as their catching tandem. They’ve combined for a decent .272/.309/.440 line, with Wong supplying some power while McGuire has done a serviceable job reaching base. Neither Wong nor McGuire stands as an obvious roadblock to an addition behind the plate but their cumulative production has been solid. Manager Alex Cora was noncommittal on bringing Alfaro up, telling reporters today the club is “very comfortable with Reese and Wong” (relayed by Chris Cotillo of MassLive). Cora expressed his hope that Alfaro would stick in the organization even if the Sox don’t call him up this week, though it remains to be seen if he’ll find a better immediate opportunity elsewhere.

• Nationals LHP Sean Doolittle

Doolittle’s return stint in Washington last year was cut short by a UCL internal brace procedure. He returned on a minor league deal but has been behind schedule as he works back to game shape. The 36-year-old has been on the injured list all season. He began a rehab stint a few days ago and has thrown two innings between Low-A and High-A. It seems likely he’ll remain with Washington and make it back to Triple-A Rochester before much longer.

• Rangers LHP Danny Duffy

Duffy has spent the entire season on the injured list. He’s working back from forearm issues that have prevented him from throwing a major league pitch since July 2021. It’s unclear when he’ll be ready to return to game action.

• Rays OF Ben Gamel

Gamel has had a solid showing in Triple-A since signing a non-roster pact in Spring Training. The left-handed hitting corner outfielder has a .257/.387/.436 line over 124 plate appearances for the Rays’ top affiliate in Durham. He’s walking at a stellar 17.7% rate against a manageable 24.2% strikeout percentage. He spent a couple weeks on the injured list earlier this month but returned to the Bulls’ lineup a week ago.

Unfortunately for the veteran, he could find it hard to crack a quality Tampa Bay outfield. Randy Arozarena has left field secured and the lefty-swinging Josh Lowe has had a breakout year to claim most of the right field reps. Luke Raley and Manuel Margot — neither of whom can be optioned to the minor leagues — are also in the outfield mix; Raley, in particular, has played very well this season. Gamel passed on his CBA opt-out dates in March and May.

• Brewers OF Tyler Naquin

Naquin was an Article XX(B) free agent who didn’t break camp with the big league club. He split the 2022 campaign between the Reds and Mets, combining to hit .229/.282/.423 over 334 trips to the plate. The left-handed hitting outfielder has only played 13 games with Triple-A Nashville after signing with the Brewers, hitting .250/.294/.375 with a pair of homers. He’s been on the minor league injured list since April 28.

• Tigers RHP Trevor Rosenthal

Rosenthal has had his last couple seasons washed away by injury. He lost 2021 to thoracic outlet syndrome and hip surgery, while his ’22 campaign was wiped out by hamstring and lat strains. The Tigers took a look at the one-time star closer in Spring Training and kept him in the organization with their highest affiliate in Toledo. Rosenthal pitched twice in the season’s first week before being placed on the minor league IL with a sprained throwing elbow.

• Giants RHP Joe Ross

Ross is recovering from last June’s Tommy John surgery and will spend most of the year on the injured list. He bypassed his first two opt-out chances and seems likely to do so again.

• Twins RHP Aaron Sanchez

Sanchez served a depth role for Minnesota last season, logging 60 innings over 15 outings (ten starts). He was tagged for a 6.60 ERA at the MLB level but performed well enough in Triple-A the organization brought him back. The former ERA champ has started ten games with their top affiliate in St. Paul this year. He has a 4.17 ERA over 41 frames. His 49.2% ground-ball rate is solid but he’s walked nearly 16% of batters faced while punching hitters out at just an 18.8% clip. Even with injuries to Tyler Mahle and Kenta Maeda, the Twins have had one of the game’s best rotations through two months.

• Padres RHP Craig Stammen

Stammen suffered a capsule tear in his shoulder in Spring Training. The 39-year-old has spent the year on the injured list and has admitted the injury might unfortunately end his career.

The first comes five days before the start of the season. For players who pass on that initial opt-out, they have additional windows to explore the open market on both May 1 and June 1 if they’ve yet to secure a spot on the 40-man roster. As that second opt-out date nears, it’s worth checking in on a few players with opt-outs under the CBA. We’ll also look at a few players who don’t meet those criteria but reportedly negotiated forthcoming opt-out dates into their own non-roster deals.

• Reds RHP Chase Anderson

Anderson was an Article XX(B) player who passed on his first opt-out chance. The 35-year-old finished last season with nine outings (seven starts) for the Reds, allowing a 6.38 ERA in 24 innings. He returned to the organization and has started five games for their top affiliate in Louisville. He carries a 4.30 ERA over 23 frames with a modest 19% strikeout rate while walking 13% of opposing hitters. It’s not a great first few weeks but the Reds don’t have much certainty behind their top three starters. Connor Overton is on the injured list, while Luis Cessa has been rocked for 20 runs in 16 2/3 innings.

• Angels RHP Chris Devenski

Devenski also forewent his Spring Training opt-out. The 32-year-old accepted a season-opening assignment to Triple-A Salt Lake, where he’s made seven relief outings. In nine innings, he’s allowed four runs with nine strikeouts and three walks. It’s a decent if not overwhelming performance. Devenski was an elite multi-inning relief option for the Astros between 2016-17 but he’s battled injuries and performance fluctuations since then. He threw 14 2/3 MLB innings between the Diamondbacks and Phillies last year, allowing an 8.59 ERA with a modest 17.5% strikeout rate but only walking one of the 67 hitters he faced. The Angels have a number of relievers who can’t be optioned to the minor leagues, perhaps reducing their flexibility to add another player of that ilk in Devenski.

• Nationals LHP Sean Doolittle

Doolittle bypassed an opt-out chance in Spring Training after returning to Washington over the winter. He’s spent the year on the injured list as he continues to work back from last summer’s internal brace UCL surgery. The veteran threw a live batting practice session this week and could see game action in the not too distant future (via MLB.com injury tracker). It stands to reason he’ll stick with the Nats.

• Rangers LHP Danny Duffy, OF Rafael Ortega

Duffy has spent the season on the injured list. He’s working back from forearm issues that have prevented him from throwing a major league pitch since July 2021. He already passed on a Spring Training opt-out and seems likely to do so again.

Ortega built an April 29 opt-out date into the minor league deal he signed with the Rangers earlier this month. He’d spent the spring in camp with the Yankees but didn’t crack New York’s roster and retested the market. Since signing with Texas, he’s played 17 games for Triple-A Round Rock. He carries a middling .219/.324/.313 line with one homer through 74 plate appearances. He’s drawing plenty of walks but not hitting for power and striking out a little more often than he has in recent seasons.

The lefty-hitting outfielder is coming off a reasonable .241/.331/.358 showing for the Cubs in 2022. He’s capable of playing all three outfield spots but is probably best suited for a corner. Texas has gotten strong early-season work from minor league signee Travis Jankowski and has Adolis García and Leody Taveras penciled into starting roles. The Rangers haven’t gotten much production from any of their left field options aside from Jankowski, though, and it’s questionable how long the journeyman can keep up anything approaching his current .340/.415/.447 pace.

• Rays OF Ben Gamel

Gamel, 31 next month, has been a decent left-handed platoon outfielder in recent seasons. He typically hits around a league average level, including a .232/.324/.369 line over 115 games with the Pirates last year. After signing with the Rays, he’s off to a .217/.316/.406 start in 79 plate appearances at Triple-A Durham. He’s walking at a customarily strong 12.7% clip but has gone down on strikes in more than 30% of his trips. Left-handed hitting outfielders Josh Lowe and Luke Raley have had excellent starts for Tampa Bay, which could make it hard for Gamel to play his way into the MLB mix anytime soon.

• White Sox OF Billy Hamilton

Hamilton, 32, returned for a second stint with the White Sox over the winter. He’s appeared in 14 games with Triple-A Charlotte but hasn’t produced, stumbling to a .150/.292/.175 batting line. The speedster has been successful on all three of his stolen base attempts but likely needs to show a little more at the plate to earn the pinch-running/defensive specialist role he’s played for a number of teams over the past four-plus seasons. The White Sox recently selected Adam Haseley onto the MLB roster to serve as a glove-first fourth outfielder.

• Phillies RHP Jeff Hoffman

Hoffman didn’t sign early enough to receive the automatic opt-out for Article XX(B) free agents. He negotiated opt-out chances on both May 1 and July 1 into his April deal with the Phils. The righty has pitched seven times for their top affiliate in Lehigh Valley, allowing eight runs across 7 2/3 innings. He’s punched out 13 hitters but handed out five free passes. Hoffman had a reasonable 3.83 ERA through 44 2/3 frames for the Reds last season, missing bats at a league average rate but walking nearly 12% of his opponents. The Phils only have three out of eight relievers who can’t be optioned to the minors, giving them some room to add the veteran if they’re intrigued by Hoffman’s swing-and-miss capabilities.

• Brewers OF Tyler Naquin

Naquin was an Article XX(B) free agent who didn’t break camp with the big league club. He split the 2022 campaign between the Reds and Mets, combining to hit .229/.282/.423 over 334 trips to the plate. The left-handed hitting outfielder has played in 12 games for Triple-A Nashville, hitting .273/.319/.409. He’s not hitting for much power in the early going and has never been one to take too many walks. Naquin spent a bit of time on the injured list this month but was reinstated earlier in the week.

Milwaukee lost center fielder Garrett Mitchell to a season-threatening shoulder procedure and has gotten middling offensive production from rookie outfielder Joey Wiemer. They’re soon to welcome Tyrone Taylor back from the injured list, though, and Naquin’s serviceable but unexceptional Triple-A production may not force the front office’s hand.

• Tigers RHP Trevor Rosenthal

Rosenthal has had his last couple seasons washed away by injury. He lost 2021 to thoracic outlet syndrome and hip surgery, while his ’22 campaign was wiped out by hamstring and lat strains. The Tigers took a look at the one-time star closer in Spring Training and kept him in the organization with their highest affiliate in Toledo. Rosenthal pitched twice in the season’s first week before being placed on the minor league IL with a sprained throwing elbow. Jason Beck of MLB.com tweeted yesterday that Rosenthal is headed for physical therapy, suggesting he won’t be ready for game action in the near future.

• Giants RHP Joe Ross, C Gary Sánchez

Ross is recovering from last June’s Tommy John surgery and will spend most of the year on the injured list. He bypassed his first opt-out chance in March and seems likely to do the same next week.

Sánchez’s May 1 opt-out was built into his contract, as he didn’t sign early enough to receive the automatic opt-out under the CBA. The general expectation was that the veteran backstop would play his way onto the big league roster. That was particularly true once San Francisco lost Roberto Pérez to a season-ending shoulder injury. Sánchez hasn’t done anything to force the issue with Triple-A Sacramento, though.

He’s hitting a woeful .191/.350/.213 without a home run and a 25% strikeout rate over 13 games. Sánchez connected on 16 longballs in the majors for the Twins last year but only reached base at a .282 clip. There’s a path to playing time behind the dish at Oracle Park. Still, Sánchez’s early performance hasn’t been what the organization envisioned. Promoting him would lock in the prorated portion of a $4MM salary for this season, which could prove a disincentive for the club.

• Twins RHP Aaron Sanchez

Sanchez served a depth role for Minnesota last season, logging 60 innings over 15 outings (ten starts). He was tagged for a 6.60 ERA at the MLB level but performed well enough in Triple-A the organization brought him back. He’s started five games with St. Paul this season, logging 22 1/3 innings. While his 2.42 ERA is excellent, it belies a middling 19.2% strikeout percentage and a huge 17.2% walk rate. Minnesota has quite a bit more rotation depth than they did last summer and would probably look to players already on the 40-man roster (i.e. Simeon Woods Richardson and Louie Varland) before tabbing Sanchez if injuries necessitate.

• Padres RHP Craig Stammen

Stammen suffered a capsule tear in his shoulder in Spring Training. The 39-year-old has spent the year on the injured list and has admitted the injury might unfortunately end his career.

This year, Opening Day is March 30, meaning that first opt-out opportunity is coming up this Saturday, March 25. Teams will have to make some decisions between now and then about whether or not to give these players roster spots or let them return to the open market to pursue other opportunities. With many teams dealing with spring injuries, some of these players should be able to find opportunities elsewhere if they can’t find it with their current organization. Their current clubs can prevent them from opting out by giving them a roster spot, but that may involve cutting someone else.

Players who don’t meet this criteria can also negotiate opt-out provisions into their contracts. First baseman Luke Voit has less than six years service time but has an opt-out in his deal with the Brewers, which he recently pushed to this Friday. But the players listed below will have them automatically.

Angels: RHP Chris Devenski

Devenski, 32, had some good seasons with the Astros in 2016 and 2017 but fell off in the two years after. He’s been either hurt or ineffective in the past three campaigns, not reaching 15 innings pitched in any of them. He tossed 14 2/3 frames last year between the Diamondbacks and Phillies with a combined 8.59 ERA. The Halos have a large number of relievers on their roster that can’t be optioned, which doesn’t leave a lot of room for someone like Devenski.

Braves: IF Ehire Adrianza, OF Kevin Pillar and RHP Jesse Chavez

Adrianza, 33, is a light-hitting utility infielder who was with the Nationals last year until the Braves acquired him at the deadline, though injuries limited him to just six games with Atlanta. Pillar, 34, has long been known as a glove-first outfielder. He was drafted by the Blue Jays and worked his way up to the majors when Alex Anthopoulos, now the president of baseball operations in Atlanta, was with the Jays. Pillar got into four games with the Dodgers last year before a shoulder fracture ended his season. Chavez, 39, started last year with the Cubs but was flipped to Atlanta in April for Sean Newcomb. The Braves then sent him to the Angels in the Raisel Iglesias deal but claimed him off waivers a few weeks later. He ended up throwing 69 1/3 innings on the year with a 3.76 ERA.

It’s possible that all three of these guys are on the verge of getting roster spots. The club recently optioned various players on the 40-man, including Vaughn Grissom, Braden Shewmake, Jordan Luplow, Eli White and Nick Anderson. Grissom and Shewmake were in competition for the shortstop job but it seems they will get more seasoning in the minors while Orlando Arcia takes the gig, with Adrianza in backup infield role. Pillar was competing with Luplow and White for a job as a backup outfielder but it seems he may get the nod. The club clearly loves Chavez based on the fact that they acquired him twice last year. The 40-man roster already has a couple of open spots before they’ve even moved Huascar Ynoa and Tyler Matzek to the 60-day injured list. Both of them are going to be out for most or perhaps all of the year due to Tommy John surgery. Atlanta could therefore have four roster spots at their disposal, allowing them to select these three and whichever of Jared Shuster or Dylan Dodd gets the fifth starter job.

Brewers: OF Tyler Naquin

Naquin, 32 next month, is a solid platoon bat from the left side. For his career, he’s hit .274/.326/.468 against righties for a 109 wRC+, compared to a .210/.272/.339 line and 62 wRC+ against southpaws. With Tyrone Taylor set to miss the first month of the season with an elbow injury, the club could use another outfielder. As mentioned above, the Brewers also have Voit in camp on a minor league deal, which makes things a little crowded. Voit could have opted out of his deal last week but agreed to push his decision because he and the club seem happy with each other, but the roster decisions still need to be made.

Opening one spot on the 40-man will be easy, as Justin Wilson is set to miss most of the year recovering from Tommy John surgery and will surely be placed on the 60-day IL shortly. Aaron Ashby could also go to the 60-day as he’s out with a shoulder injury, though the latest reporting indicated that he was targeting a mid-May return, which the club might not want to close off. Beyond the 40-man questions, there’s the fit on the active roster to think about, as adding both Voit and Naquin would likely involve optioning Owen Miller and Brice Turang, or perhaps designating Keston Hiura for assignment. Brewers general manager Matt Arnold recently spoke about some of the “tough decisions” the club has to make.

Dodgers: OF Jason Heyward

Heyward signed an eight-year, $184MM deal with the Cubs prior to the 2016 campaign but never really lived up to expectations. Outside of the shortened 2020 season, he never posted a wRC+ higher than 100, which is league average. Last year, he hit .204/.278/.277 for a wRC+ of 61 in 48 games. He went on the injured list in late June with a knee injury and never returned. While on the IL, the Cubs announced they would be releasing Heyward at season’s end, despite still having one year left on his contract.

The Dodgers signed him to a minor league deal and will be responsible for paying him just the MLB minimum salary for any time spent on the big league roster, with the Cubs on the hook for the majority of his salary. Despite not hitting much in recent years, he’s always gotten good grades for his defense, though those numbers have naturally declined as he’s aged. Manager Dave Roberts has recently suggested Heyward is likely to make the club. They’ll need to open a roster spot but could do so easily by transferring Gavin Lux to the 60-day IL, as he’s expected to miss the entire season with a torn ACL.

Giants: C Roberto Pérez and RHP Joe Ross

Pérez, 34, has long been a well-regarded defensive catcher with a subpar bat. He has a career batting line of .207/.298/.360 but has also racked up 79 Defensive Runs Saved. He only played 21 games for the Pirates last year before hamstring surgery ended his season. The Giants already have two catchers on the roster in Joey Bart and Rule 5 pick Blake Sabol, but the latter can play other positions and has recently been getting some outfield work. Perhaps that allows Pérez to make the club as a more straightforward backup to Bart, which will necessitate a roster move. Luis González is expected to miss the first half of the season due to back surgery and could be move to the 60-day IL to open a spot for Perez.

Ross, 30 in May, had the second Tommy John surgery of his career last June and isn’t set to return for a while. He signed a minor league deal with the Giants in January and presumably intends to stick with the organization as he rehabs.

Mariners: OF Kole Calhoun

Calhoun, 35, has had many strong years at the plate but is coming off a pair of rough ones. In 2021, he made multiple trips to the IL for hamstring issues and only got into 51 games. Last year, he hit .196/.257/.330 with the Rangers, striking out in 32.1% of his plate appearances.

The M’s will likely have Julio Rodríguez, Teoscar Hernández, Jarred Kelenic and AJ Pollock in their outfield mix. Some recent injuries to Taylor Trammell and Dylan Moore perhaps helped Calhoun’s chances of carving out a bench role, but the club also has Cooper Hummel and Sam Haggerty on hand as outfield-capable utility players, and outfield prospect Cade Marlowe is on the 40-man roster.

Marlins: IF Yuli Gurriel and IF José Iglesias

Gurriel, 39 in June, has been an excellent hitter for much of his career but inconsistent of late. He dipped in 2020 but bounced back to winning a batting title in 2021. Another dip followed last year, as he hit .242/.288/.360 for a wRC+ of 85. Iglesias, 33, has long been a light-hitting glove-first shortstop, though his defensive grades have slipped of late. With the Rockies last year, he hit .292/.328/.380 for a wRC+ of 85.

Gurriel seems likely to get a spot based on the way he and the club danced with each other this offseason. They reportedly offered him a $2MM deal at one point but withdrew it after a week went by without a response, later circling back to get this minor league deal done. Iglesias also makes sense as insurance for the club now that Miguel Rojas has been traded to the Dodgers, leaving utility man Joey Wendle as the top option at short. If they want to select both, they’ll need two roster spots. One of them should be easy with Max Meyer set to miss most of the season due to Tommy John surgery and bound for the 60-day IL shortly.

Mets: RHP Tommy Hunter

Hunter, 36, is a 15-year veteran who has thrived as a reliever over the past 10 of those. However, injuries have been an issue recently, as he hasn’t topped 25 innings in a season since 2018. With the Mets last year, he posted a 2.42 ERA in 22 1/3 innings but made multiple trips to the IL due to back tightness.

The Mets’ bullpen suffered a huge blow recently with Edwin Díaz likely done for the season due to knee surgery, as Sam Coonrod and Bryce Montes de Oca also deal with injuries. That could open up a window for someone like Hunter, but the Mets have also said they’d prefer to have some optionable pitchers in the bullpen, which could work against him. If they do want Hunter in the mix, opening a roster spot will be easy with Díaz and José Quintana both destined for the 60-day IL soon.

Nationals: RHP Chad Kuhl, RHP Alex Colomé and LHP Sean Doolittle

Kuhl, 30, had some decent seasons pitching for the Pirates but had an inconsistent season with the Rockies last year. He had a 3.49 ERA through the end of June but then an 8.60 the rest of the way, finishing up at 5.72 combined. Colomé, 34, has been an effective reliever for many years but also found it hard to succeed in Coors. He signed with the Rockies last year and posted a 5.74 ERA on the year. He’s not too far removed from a ridiculous 0.81 ERA in the shortened 2020 season and a 2.80 in 2019.

Kuhl seems to be the favorite to replace Cade Cavalli in the rotation, with the latter set to miss the whole season due to Tommy John surgery. Colomé makes sense for the club given they have few settled options in their bullpen. Opening up two spots should be straightforward since Cavalli and Tanner Rainey are both candidates for the 60-day IL due to Tommy John surgery.

As for Doolittle, he recently spoke about taking it slow in his rehab from last year’s elbow sprain and brace procedure. He isn’t likely to be ready for Opening Day but seems happy with his rehab process and would therefore likely forgo his first opt-out opportunity.

Padres: IF Rougned Odor and RHP Craig Stammen

Odor, 29, has long been a one-dimensional hitter, providing power and little else. With the Orioles last year, he hit 13 home runs but slashed .207/.275/.357 for a wRC+ of 80. He’ll be trying to force his way into a bench role in San Diego. One spot will go to a backup catcher, leaving three spots for Odor, Adam Engel, José Azocar, Brandon Dixon, Matthew Batten, Tim Lopes and David Dahl. The club doesn’t have an obvious candidate for the 60-day IL, which could work against non-roster players like Odor, Lopes and Dahl.

As for Stammen, 39, he recently revealed that he suffered a torn capsule in his right shoulder and strained sub scapula and likely won’t pitch ever again.

Pirates: C Kevin Plawecki

Plawecki, 32, is a career .235/.313/.341 hitter, leading to a wRC+ of 80. That’s bit below average, even for a catcher, but he has good grades for his defense and framing and is considered a strong clubhouse leader. When he was designated by assignment by the Red Sox last year, some players, including current Pirate Rich Hill, spoke publicly about how much they didn’t like Plawecki’s departure. The Rangers added him for the final games of the season even though they weren’t in contention, seemingly valuing those same intangibles.

The Bucs will have Austin Hedges as their primary catcher but seem likely to select Plawecki to be the backup. Hedges is one of only two backstops currently on the 40-man. The other is prospect Endy Rodríguez, who was optioned to Triple-A last week. If Plawecki in indeed added, it’s possible that Jarlín García is headed for the 60-day IL, as he’s been shut down for the next four to five weeks with a nerve injury in his biceps area and won’t be able to return until May at the earliest.

Rangers: C Sandy León, LHP Danny Duffy and RHP Ian Kennedy

León, 34, is generally regarded as a glove-first option behind the plate. Last year, he split his time between the Guardians and Twins, hitting .169/.298/.211. For his career, he’s racked up 34 Defensive Runs Saved and has positive framing numbers from FanGraphs.

The Rangers have three catchers on their 40-man roster in Jonah Heim, Mitch Garver and Sam Huff. León might have a better path to playing time elsewhere, as multiple clubs around the league are dealing with injuries to their catching corps. Carson Kelly of the Diamondbacks was recently diagnosed with a forearm fracture, leaving them with youngsters Gabriel Moreno and José Herrera as their top two. The Athletics only have two catchers on their roster right now and one of them, Manny Piña, will open the season on the injured list.

Duffy, 34, spent years as an effective starter for the Royals, currently sporting a 3.95 career ERA in 234 games. However, he hasn’t pitched July of 2021, when a flexor strain in his forearm sent him to the IL. The Dodgers acquired him from the Royals, hoping for a return to health in the second half, but he suffered a setback. He then underwent surgery but the Dodgers took a chance on him again, signing him to a $3MM deal with a club option for 2023 and hoping for a return late in 2022. He never made it back to the mound and the Dodgers declined his option at season’s end. General manager Chris Young listed Duffy as a closer candidate in January, but he’s yet to appear in a game this spring.

Kennedy, 38, had an effective half season of relief with the Rangers in 2021, posting a 2.51 ERA before getting flipped to the Phillies. He had a 4.13 ERA after the deal and then slumped to a 5.36 mark with the Diamondbacks last year. The club doesn’t currently have an obvious candidate to put on the 60-day IL, which could work against Kennedy’s chances of cracking the roster.

Rays: IF/OF Charlie Culberson and OF Ben Gamel

Culberson, 34 next month, is a veteran journeyman who brings much defensive versatility to the table. He’s played every position except catcher and center field in his career. With the Rangers last year, he hit .252/.283/.357 for a wRC+ of 81.

Gamel, 31 in May, was with the Pirates last year and hit .232/.324/.369 for a wRC+ of 97. He’s had modest platoon splits for his career but they were exaggerated last year. The left-handed hitter slashed .252/.342/.409 against righties for a wRC+ of 112 but just .175/.273/.258 against southpaws for a wRC+ of 56.

The Rays have a tight roster and spent most of the winter making cuts from it, which could make it tough for either of these players to make it. But if either played is deemed worthy, Shane Baz is destined for the 60-day IL soon due to his Tommy John rehab, making it easy to open a spot for someone.

Reds: OF Chad Pinder, RHP Chase Anderson and RHP Hunter Strickland

Pinder, 31 next week, has spent his entire career with the Athletics until reaching free agency this winter. He’s a super utility guy, able to play anywhere on the field but catcher. He’s didn’t have his best season last year, walking just 3.7% of the time and striking out at a 31.1% clip, but his career batting line is a serviceable .242/.294/.417 for a wRC+ of 96.

Anderson, 35, had some good years on his track record but hasn’t been able to post an ERA under 6.00 since 2019. He got into nine games for the Reds last year with a 6.38 ERA. He was recently transferred from minor league camp to major league camp, suggesting he has a legitimate chance at earning a job.

Strickland, 34, had some good years with the Giants but has gone into journeyman mode recently. He made 66 appearances with the Reds last year, finishing with a 4.91 ERA while walking 11.6% of batters faced.

The Reds should be able to open a roster spot by transferring Justin Dunn to the 60-day IL, as he’s going to be out for a few months with a shoulder issue.

Rockies: IF Mike Moustakas

Moustakas, 34, had many good years with the Royals and Brewers but his four-year deal with the Reds didn’t go very well. He was fine in the shortened 2020 season but largely injured and ineffective for the past two years. He got into 78 contests last year but hit just .214/.295/.345.

Moving his home to Coors Field could give him a boost if he’s healthy. The Rockies could use help at third base after second baseman Brendan Rodgers suffered a potentially season-ending injury. The club’s plan is to move Ryan McMahon from third to second, freeing up the hot corner for someone like Moustakas.

Opening up a spot should be straightforward, with Rodgers and Sean Bouchard both set to miss extensive time and easy calls to be placed on the 60-day IL.

Royals: OF Jackie Bradley Jr. and IF Matt Duffy

Bradley, 33 next month, has long been an excellent defender with an okay bat, but his offense has been awful for the past two seasons. Last year, splitting his time between the Red Sox and Blue Jays, he hit .203/.255/.311 for a wRC+ of 56.

Duffy, 32, is a versatile utility player who can cover any infield position and has some limited corner outfield experience. He’s not coming off a great year at the plate, as he hit .250/.308/.311 with the Angels for a wRC+ of 78, but he’s had better results in the past.

The Royals optioned a few notable position players earlier today, potentially open the door for these two and Franmil Reyes to make the Opening Day squad. They can open up one 40-man roster spot by moving Jake Brentz to the 60-day IL, as he’ll be rehabbing from Tommy John surgery, but finding two more spots will require alternative solutions.

Tigers: IF César Hernández and RHP Trevor Rosenthal

Hernández, 33 in May, is primarily a second baseman who is coming off a bizarre power surge and then a blackout. He had never hit more than 15 home runs in a season until he hit 21 in 2021, but then he had just a single homer last year. His final batting line with the Nats last year was .248/.311/.318, wRC+ of 79. Assuming Nick Maton is taking the third base job in Detroit, Hernández is competing for a bench spot along with players like Zack Short, Andre Lipcius and Andy Ibañez.

Rosenthal, 33 in May, has occasionally been one of the best relievers on the planet, including his 2020 campaign. He posted a 1.90 ERA over 23 appearances, striking out 41.8% of batters he faced. However, various injuries have prevented him from pitching at all in the past two seasons. He recently spoke about how he may not be ready for Opening Day but is happy with his rehab process with the Tigers. It’s possible he forgoes his opt out in order to continue his work with the training staff.

The club doesn’t have an obvious 60-day IL candidate and they might also want to add non-roster invitees like Chasen Shreve or Trey Wingenter, creating a bit of a roster squeeze.

Twins: RHP Aaron Sanchez

Sanchez, 30, had an excellent season back in 2016, posting an ERA of 3.00 over 30 starts with the Blue Jays. Unfortunately, injuries have diminished his workload and results in recent years. He had a 6.60 ERA in 15 appearances for the Nationals and Twins last year.

He twice accepted outright assignments with the Twins last year and then re-signed on a minor league deal in the winter. He doesn’t seem to have a path to a roster spot at the moment but seems to be comfortable with the organization. He’ll soon have a chance to return to the open market but the relationship is good enough for him to stick around.

White Sox: IF Hanser Alberto and OF Billy Hamilton

Alberto, 30, is a light-hitting utility option. He spent last year with the Dodgers, spending time at all four infield positions in addition to some corner outfield work. He hit .244/.258/.365 for a wRC+ of 73. He was signed to bolster Chicago’s uncertain second base position, but that was before they solidified it by adding Elvis Andrus.

Hamilton, 32, has long been one of the game’s best defenders in the outfield and speediest baserunners. However, hit bat has always lagged behind. He got into 37 games between the Marlins and Twins last year but hit .050/.136/.050. His career batting line is .239/.292/.326 for a wRC+ of 66. The club came into spring with a question mark in right field but it seems like prospect Oscar Colás is trending towards taking that job.

Song, 25, is an interesting case, given he’s spent the past three years in the navy after being drafted by the Red Sox in the fourth round of the 2019 draft. He’s also not been fully discharged, only placed in active reserve, which means he’ll be able to play baseball. It does mean he’ll still have navy commitments though, with an earlier report stating he’s effectively on part-time duty, which still requires one weekend per month and two full weeks each year. It’s not clear how that would’ve played out over the season.

In any case, Song was looking to get back up to speed quickly after three years out. As a Rule 5 draftee, the Phillies would have to keep him on the active roster for the entire season, or place him on waivers and send him back to the Red Sox if he clears. The injury does change things somewhat, as should Song open the season on the injured list the Phillies can still send him on a rehab stint to the minors for up to 30 days. He still can’t be optioned to the minors, but the Phillies would just need to ensure he spends at minimum 90 days on the active roster this season.

Here’s some other injury notes from around the game:

• Evan Woodbery of MLive relays that Tyler Nevin’s MRI on his oblique showed a Grade 1 strain. The Tigers said yesterday that Nevin’s strain was “mild”, but offered no other details on when he might be available. As Woodbery says, MLB’s Health and Injury Tracking System says hitters typically take 27 days to recover from a Grade 1 strain. That’s not a concrete number, but it would appear to put Nevin in doubt for Opening Day. Nevin, acquired from the Orioles this winter, was competing for a bench spot on the Tigers roster this year. The 25-year-old hit .197/.299/.261 with two home runs across 184 plate appearances for Baltimore last year.
• Sticking with the Tigers, and right-hander Trevor Rosenthal threw a bullpen yesterday and felt great, Woodbery reports. He’ll throw a live bullpen on Tuesday, with the hope being that he’ll be ready to step into a live game after that. Rosenthal, signed to a minor league deal by the Tigers this winter, hasn’t appeared in the big leagues for the past two seasons due to a range of injuries, including thoracic outlet syndrome, hip labrum surgery and a recurring hamstring injury. While it wouldn’t be a surprise to see Rosenthal need a little longer than Opening Day to be ready, the former All Star looks a good chance to get some opportunities in Detroit’s bullpen this year.
• The Mariners won’t have right-hander Casey Sadler up to speed by Opening Day, but he is making progress in his return from rotator cuff and labrum surgery, as Ryan Divish of the Seattle Times reports. Sadler missed the entire 2022 season, but faced hitters for the first time yesterday in a live batting practice session at Seattle’s spring training complex. Sadler, who was designated for assignment this winter but re-signed with the team on a minor league deal, put in easily his best season in 2021, working to a 0.67 ERA over 40 1/3 innings. It’s unclear what’s next for the former 25th round pick, but he’ll continue to work his way back with a view to regaining his spot in Seattle’s bullpen sometime this season.

MARCH 8: The Tigers have a couple of injury situations to monitor, as relayed by Evan Petzold of the Detroit Free Press. Infielder Tyler Nevin removed himself from batting practice yesterday and reported feeling soreness in his oblique. Meanwhile, fellow infielder Andy Ibáñez sprained the fourth finger on his left hand while preparing for the World Baseball Classic.

In Nevin’s case, the severity of the issue isn’t yet known, but oblique issues are notoriously tricky to deal with. As Petzold points out, even a mild oblique strain can potentially lead to a month-long absence. Manager A.J. Hinch says that Nevin is headed for an MRI, which will determine the next steps. In the case of Ibáñez, the issue seems less concerning. Though his finger is swollen, it’s not broken. Ibáñez plans to sit out of WBC action for a few days and seems confident he’ll be recovered after that.

These two injuries could potentially have implications for the club’s plans, as both players are part of a competition for the open third base job. The club non-tendered Jeimer Candelario in the winter and has various players jockeying for the role of his replacement. At this point, it seems the most likely scenario involves the left-handed hitting Nick Maton taking the strong side of a platoon. Maton actually has reverse splits in his career so far, but in a small sample of 216 plate appearances.

Both Nevin and Ibáñez hit from the right side and could potentially take the small side of a platoon with Maton, though the injuries could delay that plan. If those two players have to miss any time, it perhaps increases the chances of Andre Lipcius, Ryan Kreidler, Zack Short or César Hernández seizing some playing time. Hernández is a switch-hitter with the other three all hitting right-handed.

“I like the way he swings the bat, and he’s increasing his versatility, which is the point of camp for him,” Hinch said about Lipcius. “He’s doing what he’s always done.” Lipcius has primarily played third base in the minors, but has also seen some decent time at second and a very brief stint at first. He hit .277/.391/.435 between Double-A and Triple-A last year for a wRC+ of 128. He’s yet to make his major league debut but was added to the 40-man roster in November.

Elsewhere in Tigers’ camp, Trevor Rosenthal will be attempting to get back to the big leagues after signing a minor league deal with the club. He wasn’t able to appear in either of the past two seasons due to various setbacks, including thoracic outlet surgery, hip labrum surgery and a recurring hamstring injury. Though Rosenthal will be hoping for better health this year, it seems there’s still some work to do and his return isn’t imminent.

“There’s no need to have a sense for a timeline,” Hinch tells Petzold. “It does not matter when he’s ready as long as he’s healthy. We’re not going to push it. There is no artificial date. Opening Day is not something that’s feasible. We’re going to be very strict and diligent with our work with him.”

Rosenthal says the injuries are behind him now, but he’s on board with the plan the club has laid out for him. “I want to be intentional about taking the right steps and making sure I am ready, and really utilizing the time that’s left in camp,” Rosenthal says. “I think, in these three weeks, I’ll be able to get to where I want to be, but if not, I think they’re going to do a good job of taking care of me in that regard.”

He hasn’t been healthy much in the past few years, but he was very good earlier in his career and dominant for a brief spell in 2020. He made 23 appearances that year with a 1.90 ERA and struck out an incredible 41.8% of batters faced. However, the two years on either side of that season were were essentially lost due to the aforementioned injuries.

MARCH 4: The Tigers have added veteran reliever Trevor Rosenthal on a minor league deal, the team announced. The deal includes an invite to big league spring training. It’s the second stint in Detroit for Rosenthal, who made ten appearances for the team in 2019.

Injuries have kept Rosenthal out of the past two MLB seasons, with the former All Star last appearing in 2020 for the Royals and Padres. That year, Rosenthal worked to a 1.90 ERA across 23 2/3 innings for both teams. Thoracic outlet syndrome kept him out of the 2021 season when he was on the books of the Athletics taking home an $11MM salary. The Giants signed him in 2022, but he was flipped to the Brewers for Tristan Peters while he was still rehabbing. He tossed two innings of relief on a rehab assignment for the Brewers before sustaining a lat injury that ended his 2022 season.

Originally drafted in the 21st round of the 2009 draft by the Cardinals, Rosenthal worked as a starter coming up through the minors. Yet he never made a start for St Louis, and instead quickly established himself as one of the most dominant relievers in the game after making his debut in 2012. Between 2012-15, Rosenthal amassed 96 saves and worked to a 2.66 ERA over 237 innings.

While he was still punching out batters at an elite rate in 2016, a jump in his walk rate ultimately led to a decline in numbers, and between 2016-17 Rosenthal worked to a 3.89 ERA and ultimately lost the closer role. Tommy John surgery ruled him out of the entire 2018 season, and he struggled mightily in his return pitching to a 13.50 ERA over 15 1/3 innings for the Nationals and Tigers.

That was followed by a quality sample of work in 2020, before the aforementioned injuries saw him miss the next two seasons. With that in mind, it makes it quite hard to work out exactly what the Tigers are getting in Rosenthal this year. The key thing is there does seem to be a fair bit of upside here, and if Rosenthal can work his way back into anything resembling his 2020 form, the Tigers could have a nice trade chip on their hands by the summer deadline.

Rosenthal wasn’t signed during the 2021-22 offseason, but a midseason throwing showcase led to a guaranteed contract with the Giants worth a prorated $4.5MM.  At the time of the signing, Rosenthal was recovering from a hamstring strain, and was still sidelined when the Brewers landed Rosenthal (and his contract) at the trade deadline in a swap with San Francisco.  While Rosenthal was making good progress in working his way back in rehab, Brewers president of baseball ops David Stearns said that the lat problem is “a completely new injury” that only just surfaced.

“He’s been working exceptionally hard to get back here.  He was close, the ball was coming out really good, and now we have a setback,” Stearns said.

The trade with the Giants now looks like a backfired risk for the Brewers, and yet another strange detail in what has been a bizarre five-year stretch for Rosenthal.  Tommy John surgery kept off the mound for the entire 2018 season, and he pitched only 15 1/3 innings in 2019 and then 23 2/3 innings in 2020, appearing for four different teams during that two-season span.  While his 2019 numbers were poor, Rosenthal looked quite good in 2020, leading to a one-year, $11MM free agent deal with the Athletics that resulted in Rosenthal never making an actual appearance for the A’s, due to thoracic outlet syndrome.

The $4.5MM deal was already something of a surprising total for a pitcher with Rosenthal’s recent injury track record, notwithstanding his strong career numbers.  Since it now looks like he’ll go more than two years without throwing a Major League pitch, the right-hander will probably have to settle for a minor league deal this winter.  Some questions might have to be asked about whether or not Rosenthal will continue his career in the face of all these health problems, but he is still only 32 years old.

As for Milwaukee, the team gave up minor league outfield prospect Tristan Peters to the Giants, and the lack of return on Rosenthal will surely bring some fresh criticism of the team’s deadline moves.  Between dealing All-Star closer Josh Hader to the Padres for a trade package that included Taylor Rogers, as well as the swap that brought Matt Bush from the Rangers, it was a bullpen-heavy set of transactions that (with almost four weeks of hindsight) looks to have not been enough.  Milwaukee has struggled to an 8-14 record in August, falling six games back of the Cardinals in the NL Central race and 2.5 games behind in the wild card race.

• Deadline acquisition Trevor Rosenthal left his latest appearance in Triple-A with lat soreness, per MLB.com’s Adam McCalvy (via Twitter). Picking up Rosenthal was certainly a bit of a lottery ticket for the Brewers, given that Rosenthal hasn’t pitched since 2020. Rosenthal had begun to show shades of his former self, posting a 1.90 ERA over 23 2/3 innings with the Royals and Padres. The hits keep coming for Rosenthal, who suffered a hamstring strain before the lat injury, which all came while recovering from thoracic outlet surgery.
• The Cubs will be looking to add power this offseason, writes Paul Sullivan of the Chicago Tribune. That certainly tracks for a team with a middle infield consisting of Nico Hoerner and Nick Madrigal, both of whom boast contact-first profiles at the dish. Hoerner has stepped up this season, both on the field and from a leadership perspective, making himself a key part of the Cubs’ future. Madrigal has had a less memorable campaign, but he may yet establish himself as the second baseman of the future. The power will have to come from somewhere, however, especially with Willson Contreras slated for free agency. Contreras’ 20 home runs rank second on the team behind Patrick Wisdom’s 22, and the long-time catcher is the team leader in isolated power with a .222 ISO.

In another piece from Heyman in recent days, he hedges that a bit, saying that it’s “unconfirmed” whether the Brew Crew need to reach the NLCS or the World Series. Of course, the reason that all this is so newsworthy is that the Mets have been trying to pluck the New York native from Milwaukee for essentially the past year. The Brewers denied their request to interview him this winter, given the two years that were then remaining on his contract. The Mets eventually hired Billy Eppler to serve as general manager, but could theoretically still hire Stearns in the future as well, perhaps with the president of baseball operations title he currently holds in Milwaukee. Stearns would no doubt be intrigued by moving to New York, not just because he’s from there. The Mets also have significantly higher spending power, running out a $264MM Opening Day payroll this year, doubling the $132MM number of the Brewers.

Of course, those budgetary concerns were the primary motivator of the recent Josh Hader trade. As noted in the above report from Heyman, the club then tried to compensate for Hader’s loss by boosting the lineup. They apparently tried to acquire Brandon Drury and Josh Bell, losing the bidding to the Padres in both cases. They also targeted Joc Pederson, though the Giants decided against a major selloff and didn’t end up trading him. Joey Gallo was also considered, though he ended up going to the Dodgers instead. Perhaps due to the their lackluster deadline or perhaps coincidentally, the club has gone 4-7 this month, letting the NL Central lead slip to the Cardinals, with the Brewers now 1 1/2 games back.

As for the club’s Hader-less bullpen, Stearns acquired other pitchers to try and make up that loss, with one of those being Trevor Rosenthal. The righty has previously been one of the best relievers in the sport, but injuries have limited him to less than 40 total innings since the end of the 2018 campaign. He was signed by the Giants a couple of weeks before the deadline this year and immediately placed on the injured list due to a hamstring issue. The Brewers picked him up at the deadline in a high-risk move that would potentially have a high reward if Rosenthal could return to his previous form. We are on the verge of finding out whether it pays off or not, as Rosenthal told reporters, including Todd Rosiak of the Milwaukee Journal Sentinel, that he’s going on a rehab assignment this week. He also added that he recently touched 98 mph in a workout. His most recent action was in the shortened 2020 season, when he threw 23 2/3 innings with a 1.90 ERA along with an incredible 41.8% strikeout rate. If he can get anywhere close to that level here this year, he’ll give the Brewers a much-needed boost down the stretch.

4:53PM: Minor league outfielder Tristan Peters is being dealt to the Giants in exchange for Rosenthal, MLB.com’s Adam McCalvy reports (Twitter link).

4:13PM: The Brewers have acquired right-hander Trevor Rosenthal from the Giants, Jon Heyman of The New York Post reports (Twitter link).  It makes for a very short stint for Rosenthal in San Francisco, as the Giants only just signed the veteran to a one-year, $4.5MM deal back on July 21.

It remains to be seen when Rosenthal will actually be able to take the mound for Milwaukee, as he hasn’t pitched since the end of the 2020 season due to a groin strain, thoracic outlet syndrome surgery, and then a hamstring strain that only surfaced within the last couple of weeks.  Rosenthal wasn’t expected to be ready to pitch for at least a few more weeks, so early September could be the best-case scenario for his Brewers debut.

When healthy, Rosenthal will be another arm in a Brewers bullpen that has been rather unexpectedly reshaped over the last two days.  Taylor Rogers and Matt Bush were added, while All-Star closer Josh Hader was dealt to San Diego in the blockbuster deal that brought Rogers into the fold.  Devin Williams now projects as Milwaukee’s closer, with Rogers, Bush, and incumbent setup men Trevor Gott, Brad Boxberger, Hoby Milner, and Brent Suter providing additional support in high-leverage innings.

How Rosenthal will look when he is able to pitch is another question, given the long layoff.  After missing all of 2018 due to Tommy John surgery, Rosenthal had a 13.50 ERA over 15 1/3 innings in 2019, but then rebounded for a 1.90 ERA in 23 2/3 frames with the Royals and Padres last season.  This glimmer of his old All-Star form was enough to intrigue the A’s into signing Rosenthal a one-year, $11MM deal prior to the 2021 campaign that unfortunately backfired completely on Oakland, as Rosenthal never threw so much as a pitch for the organization.

The Giants’ return in the deal isn’t yet known, though the trade reflects the team’s sudden change of direction just within the last few days.  Flipping Rosenthal probably wasn’t on the Giants’ mind on July 21, but that was also the day the team began a seven-game losing streak.  With San Francisco now under the .500 mark, the focus has now turned to selling, with Rosenthal joining Darin Ruf, Curt Casali, Matthew Boyd heading out of town, though many of the Giants’ bigger-name trade chips remain.

Rosenthal currently has a strained hamstring and is rehabbing in Arizona, per Pavlovic. He has been placed on the IL already and won’t require an active roster spot, per Susan Slusser of the San Francisco Chronicle, who adds that the corresponding move to get Rosenthal on the 40-man roster is that Mauricio Llovera has been transferred to the 60-day injured list.

Rosenthal was one of the better relievers in baseball for many seasons but has been on a rollercoaster for the past few years. From 2012 to 2017, he appeared in 328 games with a 2.99 ERA, 31.2% strikeout rate and 10.3% walk rate. He racked up 121 saves and 46 holds in that time

Unfortunately, Tommy John surgery put a halt to that and wiped out his entire 2018 season. He returned in 2019 but walked a whopping 30.6% of batters faced over a stretch of 15 1/3 innings. After that disastrous return, he had to settle for a minor league deal with the Royals for 2020. He got the train back on the tracks so well that the Royals were able to flip him to the Padres at the deadline for Edward Olivares. Rosenthal finished the shortened season with a 1.90 ERA in 23 2/3 innings, with an incredible 41.8% strikeout rate.

Based on that comeback, Oakland signed him to a one-year, $11MM deal for the 2021 season. However, a groin strain kept him on the shelf at the beginning of the year, and he later required surgery for thoracic outlet syndrome, wiping out yet another entire season.

Rosenthal had a showcase over a month ago to show that he had returned to health. The Giants have evidently been impressed by his progress, based on the fact that they were willing to slap down a significant chunk of change despite Rosenthal currently being injured. On the one hand, Rosenthal is capable of being an elite reliever, but on the other hand, he’s thrown less than 40 total innings over the past five seasons.

The Giants have run into some bullpen issues this year, making it fairly understandable that they’re willing to look outside the box for answers. Most notably, Jake McGee, who saved 31 games for them last year, ran up a 7.17 ERA this year and got released last week. Overall, the club’s relievers have a 4.19 ERA, placing the club 23rd in the majors. If Rosenthal can get healthy, he can provide a boost for them down the stretch.

As for Llovera, he was just placed on the IL a few days ago due to a flexor strain. Based on today’s transfer, it seems the club doesn’t expect him to be able to return until mid-September at the earliest.

8:45am: Free-agent right-hander Trevor Rosenthal is holding a showcase for Major League clubs at St. Thomas University in Miami Gardens today, tweets Jon Heyman of the New York Post. It stands to reason that scouts from the majority of teams will be in attendance to gauge the former All-Star’s readiness to return to a big league mound.

A healthy Rosenthal can be one of the game’s most effective relievers, as he’s shown at multiple times in the past. Unfortunately, good health has eluded him in recent years. Rosenthal underwent Tommy John surgery partway through the 2017 season, which wiped out the entirety of his 2018 campaign. He returned with the Nats and Tigers in 2019 and had lost all semblance of control over the strike zone, walking 26 of the 85 hitters he faced that season (30.6%) and plunking another four.

On the heels of that alarming season, Rosenthal settled for a minor league deal with the Royals heading into the 2020 season and quickly reestablished himself as a dominant late-inning powerhouse. He pitched just 23 2/3 innings due to the shortened 60-game schedule, but Rosenthal overwhelmed opponents with a 1.90 ERA, an elite 41.8% strikeout rate and a strong 8.3% walk rate — all while averaging 98.1 mph on his heater.

Despite that dominant showing, Rosenthal didn’t find the weighty multi-year deal he sought early in free agency, and he eventually took a one-year, $11MM from a surprise suitor: the A’s. Unfortunately for Oakland and for Rosenthal, injuries again derailed his 2021 season. A groin strain slowed Rosenthal early in Spring Training, and shoulder troubles shelved him to begin the season. Eventually, it was revealed that Rosenthal required surgery to alleviate thoracic outlet syndrome. Over the summer, while working toward what he hoped would be a late-season return, a torn labrum in his hip required yet another surgery.

Rosenthal’s career numbers — 3.36 ERA, 132 saves, 31.2% strikeout rate, 11.3% walk rate, 44.3% grounder rate, 98.1 mph average fastball — all speak to the sheer talent in his right arm. (It’s a 2.91 ERA and 10.1% walk rate if you toss out the anomalous 2019 season.) However, he’s now pitched just 39 innings since undergoing Tommy John surgery way back in Aug. 2017.

Bullpen help is always in demand, and virtually every contending team (and likely several non-contenders) will want to get a look at Rosenthal in hopes of bolstering their relief corps for the season’s second half. Given the lengthy injury layoff, he’s unlikely to command a multi-year pact, so signing Rosenthal figures to be — at worst — a short-term risk with plenty of upside. It’s not clear just yet when Rosenthal would be ready to step onto a big league mound. He’ll presumably require a minor league tune-up to reacclimate to game settings and build additional arm strength, but if he’s ready to audition for MLB clubs, he and agent Scott Boras can’t feel he’s too far off.
