The 32-year-old Rodriguez had two stints with the Red Sox this season, pitching a combined 13 2/3 innings with a 5.93 ERA but more encouraging secondary marks. While Rodriguez’s 18.8% strikeout rate is a few percentage points shy of league-average, he issued walks at a tiny 3.1% clip and kept the ball on the ground at a gaudy 59.2% rate. Metrics like FIP (4.93) and especially SIERA (2.87) are far more bullish on this year’s work.

In 170 2/3 innings in the majors, Rodriguez has pitched to a 4.80 ERA. That pedestrian mark belies more encouraging strikeout and ground-ball numbers (22.5% and 56%, respectively), although Rodriguez’s ability to miss bats and keep the ball out of the air have both been undercut by sub-par command. He’s walked 10% of his career opponents and struggled to strand the runners he does allow (career 64% left-on-base rate).

This year’s 90 mph average sinker is down nearly five miles per hour from Rodriguez’s peak, but he still pitched reasonably well in Triple-A and still managed to pile up grounders in bulk at the big league level. He’ll be a depth option for clubs seeking lefty relief in the season’s final month.

Rodriguez was selected to the 40-man roster himself on Friday, and the Sox used him heavily over the weekend. The 32-year-old southpaw pitched in three straight games from Friday through Sunday, logging 2 2/3 innings and allowing a run on four hits and no walks with one strikeout. Rodriguez was surely unavailable today for what’s effectively a doubleheader — the Sox will finish their suspended game against the Blue Jays and then play a second game versus the Jays this evening — and will be jettisoned from the roster for a fresh arm in Keller.

This weekend’s stretch of three solid appearances from Rodriguez helped to pare down a rough earned run average that now sits at a still-unsightly 5.93 on the season — albeit in just 13 2/3 innings. Rodriguez’s under-the-hood numbers are far, far better. He’s fanned a below-average 18.8% of his opponents but also sports a pristine 3.1% walk rate and a massive 59.2% ground-ball rate in this season’s 14 appearances. Metrics like xFIP (3.07) and SIERA (2.87) are much more bullish on his performance than his ERA.

That’s nothing new for Rodriguez, who sports a roughly average 22.5% strikeout rate in his career, a higher-than-average 10% walk rate and a terrific 56% ground-ball rate. In 170 2/3 innings, he’s posted a 4.80 ERA, but his respectable ability to miss bats and huge ground-ball tendencies have long led ERA alternatives to forecast better bottom-line results. Rodriguez has at times had success in the majors, but his whiffs and grounders have been undercut by persistent struggles with men on base; his career 64% strand rate is about eight percentage points worse than average.

Now that Rodriguez has been designated for assignment, he’ll be placed on waivers and made available to the other 29 clubs. A new team would owe him a prorated $2MM base salary for any time spent on the big league roster or injured list (about $344K for the remainder of the season). If he goes unclaimed, he can reject his outright assignment, become a free agent, and hope to latch on with a new club as a depth option prior to the Aug. 31 postseason eligibility deadline.

Today’s move is a swap of one veteran for another. Keller will rejoin the team after being previously designated for assignment himself, electing free agency, and returning on a minor league deal. He’s appeared in 15 games for Boston this season and pitched 37 2/3 innings of 5.30 ERA ball with a 17.8% strikeout rate, 7.7% walk rate and 49.3% ground-ball rate. He’s been working primarily as a starter in Worcester and is stretched out for long relief if needed. In 30 innings with the WooSox this season, Keller has a 3.00 ERA.

Keller is in his first season with the Red Sox organization but spent six years as a fixture on the Royals’ pitching staff. From 2018-20, he was a regular in the rotation and a steady source of quality innings. His results dipped in 2021, and by 2023 his command had deteriorated to the point where he walked a stunning 45 batters in 45 1/3 innings. Keller eventually hit the injured list and was diagnosed with thoracic outlet syndrome, which required season-ending surgery. He’s yet to rediscover his 2018-20 form (360 1/3 innings, 3.50 ERA, 16.8% strikeout rate, 9.1% walk rate, 52.1% grounder rate), but he’s still relatively young at 29 and has been outstanding in the minors recently. Over his past 22 innings in Triple-A, Keller sports a 0.82 ERA and 15-to-1 K/BB ratio.

Rodríguez, 32, signed a minor league deal with the Red Sox in the offseason. He cracked their Opening Day roster but didn’t post strong results initially. He made 11 appearances for the club with a 6.55 earned run average, the same numbers he had in limited time with them last year.

He was designated for assignment at the end of April and accepted an outright assignment after clearing waivers. He then spent about six weeks on the minor league injured list from the middle of May until late June. That has left him with just 14 1/3 Triple-A innings pitched this year, but with a strong 1.88 ERA. There’s likely a good deal of fortune in there, based on his .175 batting average on balls in play in that small sample. His 20.6% strikeout rate and 12.7% walk rate in that time were subpar, though he did get grounders at a strong 52.6% clip.

Those rate stats aren’t too far off of his major league track record. In 168 innings dating back to his 2016 debut, he has a 4.82 ERA, 22.8% strikeout rate, 10.1% walk rate and 55.7% ground ball rate. He’ll give the club a second lefty in the bullpen alongside Brennan Bernardino. He is out of options but can be retained beyond this season via arbitration if he holds onto his roster spot through the end of the year.

As for Paxton, it’s not a surprise to see him moved to the 60-day IL. He suffered a partially torn right calf muscle last week and manager Alex Cora said it was unlikely that the lefty would be able to return this year. He’s now officially ineligible to be reinstated until the second week of October. Unless the Sox make a deep playoff run and he heals up in the next two months, his season is over.

Rodríguez signed a minor league deal with the Sox over the offseason. Boston carried him on the Opening Day roster to keep him from opting out and retesting free agency. That didn’t work as the team hoped, as he surrendered 12 runs (eight earned) over 11 innings. Rodríguez ran an 11:2 strikeout-to-walk ratio and induced grounders on over 55% of batted balls, but the Red Sox clearly weren’t overly bullish on his chance to get back on track.

It is the second straight season in which Rodríguez struggled over an 11-inning stint for Boston. Oblique, shoulder and hip injuries kept him to just 11 appearances a year ago. Rodríguez also allowed eight earned runs in that season, which came on the heels of a $2MM major league free agent deal. He divided the 2021-22 seasons between the Rangers and the two New York franchises, combining for a 4.56 ERA across 107 appearances.

Rodríguez has the requisite three years of major league service to decline an outright assignment, but he has not crossed the five-year threshold necessary to retain his salary if he does so. If Rodríguez accepts the assignment, he’ll join Lucas Luetge as a veteran non-roster southpaw in Worcester. Boston has Brennan Bernardino and Cam Booser in the big league bullpen. They acquired Bailey Horn from the White Sox earlier this week. He’s on the 40-man but was immediately optioned to Worcester and hasn’t yet pitched in the big leagues.

Uwasawa, 30, signed a minor league split contract with the Rays back in January but was traded to the Red Sox after he activated an assignment clause in his deal that obligated Tampa to deal him to any club willing to offer him a 40-man roster spot. Boston indeed added Uwasawa to their 40-man, though he began the season at Triple-A after not making the club’s Opening Day roster. Since then, the right-hander has made three starts with Worcester with a 4.80 ERA in 15 innings. While those early results have left something to be desired, Uwasawa’s 26.1% strikeout rate in the minors so far is reassuring after the righty punched out a meager 17.8% of batters faced in Japan last year.

While Uwasawa did not strike out many batters during his time in Nippon Professional Baseball, it’s impossible to deny that the right-hander was effective. Across nine seasons with the Hokkaido Nippon-Ham Fighters, Uwasawa posted a strong 3.19 ERA in 1,118 1/3 innings of work. While he struck out less than 20% of batters faced during his time in Japan, Uwasawa posted an ERA below 3.50 in each of the past six seasons. That includes excellent results in 2023, when he posted a 2.96 ERA in 170 innings despite the aforementioned low strikeout rate.

It’s not yet clear what role Uwasawa will occupy with the Red Sox now that he’s been promoted to the big league club. Injuries to Brayan Bello, Garrett Whitlock, and Nick Pivetta have left depth options Josh Winckowski, Cooper Criswell, and Chase Anderson to step into the club’s rotation alongside Tanner Houck and Kutter Crawford. It’s feasible to imagine Uwasawa taking a rotation job and pushing either Anderson or Winckowski back to the bullpen, though its also possible that Uwasawa himself has been called up to be a multi-inning relief option for the club. [UPDATE: Uwasawa will indeed be used as a long reliever, manager Alex Cora told The Athletic’s Jen McCaffrey and other reporters.]

Making room for Uwasawa on the club’s roster is Rodriguez, who has struggled to a 6.55 ERA in 11 innings of work this season with a 5.25 FIP. It’s a very similar line to the one the lefty posted with Boston last year, when he posted an identical 6.55 ERA in 11 frames with a 4.71 FIP. He was limited to just those 11 innings last year by oblique, shoulder, and hip injuries that cost him the majority of the 2023 season, though his repeat performance after re-signing with the club on a minor league deal this past winter seems to have been enough for the Red Sox to decide to move on from the 32-year-old southpaw.

Boston will have seven days to trade Rodriguez or pass attempt to pass him through waivers. Should he make it through waivers unclaimed, the Red Sox will have the opportunity to outright Rodriguez to the minor leagues, at which point Rodriguez would be able to choose between remaining with the organization as non-roster depth or returning to the free agent market in search of greener pastures elsewhere. Even without Rodriguez, the Red Sox bullpen figures to be well-stocked with lefty relief options. Brennan Bernardino and Cam Booser are the two southpaws currently in the club’s bullpen, with non-roster veteran Lucas Luetge and youngster Jorge Benitez among the club’s depth options from the left side.

Rodriguez, 32, was with the Sox in 2023 but pitched just 11 innings due to oblique, shoulder and hip injuries that combined to result in three different stints on the injured list. He posted a 6.55 ERA in his short time on the mound, striking out 27.5% of his opponents against an 11.8% walk rate and 45.2% ground-ball rate. He re-signed with the Sox on a minor league deal and turned in a strong showing this spring, holding opponents to a pair of runs on nine hits and three walks with nine strikeouts in seven innings of relief. He also recorded a massive 61.9% ground-ball rate.

Looking beyond last year’s struggles, Rodriguez has a decent track record in recent years. From 2020-22, Rodriguez pitched 109 1/3 frames between the Rangers, Yankees and Mets, working to a 4.28 ERA with even more encouraging secondary marks. Rodriguez fanned 25.5% of his opponents in that time and induced grounders at a huge 55.7% clip. His 10.3% walk rate was still a couple ticks north of the league average, but the lefty offered an enticing blend of missed bats and grounders while excelling at keeping the ball in the park (0.58 HR/9). Metrics like FIP (3.14) and SIERA (3.51) were rather bullish on his work.

Uwasawa, 30, has a long track record of success in Japan’s Nippon Professional Baseball but inked a minor league pact with the Rays over the winter. He most recently tossed 170 innings with a 2.96 ERA in NPB, though that strong mark was accompanied by a lackluster 17.8% strikeout rate and sub-par velocity. Last September, MLBTR contributor Dai Takegami Podziewski noted that Uwasawa’s fastball velocity was averaging 90.8 mph during the 2023 NPB season. Uwasawa does boast a strong 7.5% walk rate, which dropped as low as 5.9% in 2023, but he’s generally viewed as a soft-tossing finesse pitcher.

It was a rocky spring for Uwasawa, who was torched for seven runs in two innings during his debut with the Rays. He had one more rough outing and a pair of solid appearances, and the Sox got a first-hand look at him as they were his opponent in two of his four official spring outings. Uwasawa finished up his Grapefruit League campaign with a grisly 13.03, thanks largely to that first meltdown, but his track record in Japan and low cost of acquisition make him a reasonable enough flier for a Red Sox club that is thin on pitching depth after trading Chris Sale and seeing Lucas Giolito and the aforementioned Murphy go down with UCL injuries.

MARCH 22: First baseman C.J. Cron and left-hander Joely Rodriguez have both exercised the uniform opt-out provision in their minor league contracts with the Red Sox, reports Alex Speier of the Boston Globe. Both players were Article XX(B) free agents — six-plus years of service time, finished the season on a major league roster or injured list — who signed minor league contracts and were thus granted a trio of mandatory opt-out opportunities: five days prior to Opening Day (today), May 1 and June 1. The Red Sox will now have 48 hours to either put Cron and/or Rodriguez on the 40-man roster. They’ll have to release either player if they decide against carrying him on the Opening Day roster.

Cron, 34, has four seasons of 25-plus homers under his belt and was consistently an above-average hitter from 2014-22. Back and neck injuries tanked his 2023 season, limiting him to 278 plate appearances with a .248/.295/.434 slash, but he has a strong track record of hitting for power — with largely even platoon splits. From 2018-22, Cron piled up 2290 plate appearances and hit .260/.331/.490 with 116 home runs. He’s only had 15 plate appearances this spring, during which he’s 2-for-11 with three walks and two strikeouts. The Red Sox are set at first base and DH with Triston Casas and Masataka Yoshida, but Cron could serve as a right-handed complement/insurance to either or perhaps some right-handed pop off the bench.

Rodriguez, 32, was with the Sox in 2023 but pitched just 11 innings due to oblique, shoulder and hip injuries that combined to result in three different stints on the injured list. He posted a 6.55 ERA in his short time on the mound, striking out 27.5% of his opponents against an 11.8% walk rate and 45.2% ground-ball rate.

It wasn’t a strong year overall for Rodriguez, but the lefty has posted far better numbers over the three preceding seasons in his return from an excellent two-year stint in Japan’s Nippon Professional Baseball. From 2020-22, Rodriguez pitched 109 1/3 frames between the Rangers, Yankees and Mets, working to a 4.28 ERA with even more encouraging secondary marks. Rodriguez fanned 25.5% of his opponents in that time and induced grounders at a huge 55.7% clip. His 10.3% walk rate was still a couple ticks north of the league average, but the lefty offered an enticing blend of missed bats and grounders while excelling at keeping the ball in the park (0.58 HR/9). Metrics like FIP (3.14) and SIERA (3.51) were rather bullish on his work.

Rodriguez has had a strong showing this spring, holding opponents to a pair of runs on nine hits and three walks with nine strikeouts in seven innings of relief. He’s also recorded a massive 61.9% ground-ball rate. He seems like he has a decent shot to make the roster, and even if the Sox don’t add him, the left-hander should command interest elsewhere.

The first uniform opt-out date on this year’s calendar falls Friday at 1pm CT. Any player can trigger his out clause at that point, and the team will subsequently be given a 48-hour window to either add him to the roster or release him. With many clubs around the league 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.

Angels: OF Jake Marisnick, LHP Drew Pomeranz

Marisnick, 33 this month, is a right-handed-hitting fourth outfielder with a plus glove and questionable bat. He can hold his own against right-handed pitching (career .237/.293/.417, 93 wRC+) but is typically overmatched by righties (.223/.274/.365, 74 wRC+). He’s having a huge spring, but the Angels already have Taylor Ward, Mike Trout, Mickey Moniak, Aaron Hicks and Jo Adell on the 40-man roster.

The 35-year-old Pomeranz was a good starter from 2016-17 and a dominant reliever from 2019-21, but he didn’t pitch in 2022-23 due to arm injuries. He’s pitched 6 2/3 innings with the Angels this spring with middling results.

Blue Jays: 3B/2B Eduardo Escobar, 1B Joey Votto

A poor season between the Mets and Angels last year set the stage for the 35-year-old Escobar to take a minor league deal. He’s long been a productive MLB hitter and even topped 30 homers back in 2019, but Escobar’s now in his mid-30s and struggling through an ugly spring while trying to win a spot in a crowded infield mix also featuring Isiah Kiner-Falefa, Santiago Espinal, Cavan Biggio, Ernie Clement and Davis Schneider.

Votto, 40, has been connected the Blue Jays seemingly forever due to his Canadian roots. He finally suited up for the Jays after agreeing to a minor league deal and homered in his first at-bat of camp. He’s had a lackluster showing at the plate in each of the past two MLB seasons, however.

Cubs: 1B/OF Garrett Cooper, RHP Carl Edwards Jr., OF David Peralta

An underrated hitter for years in Miami, Cooper slashed .274/.350/.444 in nearly 1300 plate appearances from 2019-22 before a poorly timed down showing in 2023’s walk year. He’s hitting quite well in spring training, and the Cubs don’t have a proven option at first base — though they’re understandably high on 26-year-old trade acquisition Michael Busch.

Edwards had a nice 2022 season with the Nats and posted a solid ERA in 2023 but did so with dismal K-BB numbers. He’s competing for a spot in an uncharacteristically crowded Cubs bullpen and could be squeezed out. The 32-year-old pitched for the Cubs from 2015-19, so Chicago brass knows him well. From 2022-23 in D.C., he posted a 3.07 ERA but a middling 20% strikeout rate against a 10.5% walk rate.

Peralta, 36, has a trio of hits and a walk in ten plate appearances this spring. He was an above-average hitter with the D-backs every season from 2017-20 but has been less consistent of late. He’s a left-handed hitter who’s long had glaring platoon splits and is limited to the outfield corners.

Diamondbacks: SS Elvis Andrus

Andrus is 35 but can still pick it at shortstop or second base. His once above-average speed has faded to the 30th percentile of MLB players, per Statcast, but his range at short remains excellent. Andrus hit .251/.304/.358 (81 wRC+) for the White Sox in 2023 and only has one year of above-average offense (2022) in the past six seasons.

Guardians: RHP Carlos Carrasco

Old friend Cookie Carrasco is fighting for the fifth spot in the Guardians’ rotation, and news of Gavin Williams’ season-opening stint on the injured list could further open the door for the 36-year-old (37 on Thursday) to make the team. Carrasco was torched for a 6.80 ERA with the 2023 Mets. He allowed 1.80 homers per nine frames through 90 innings, with alarming batted-ball metrics (91.5 mph average exit velocity, 48.2% hard-hit rate, 10.7% barrel rate). He was a solid mid-rotation arm as recently as 2022, when he tossed 152 innings of 3.97 ERA ball with sharp strikeout and walk rates.

Marlins: C Curt Casali

The veteran Casali has batted .201/.311/.315 over the past three big league seasons — a 78 wRC+ in 503 plate appearances. The 35-year-old is off to a rough start in camp and is a long shot to unseat defensive-minded Nick Fortes or Christian Bethancourt, both of whom are already on the 40-man roster.

Mets: 1B/DH Ji Man Choi

From 2017-22, Choi hit .254/.363/.465 (130 wRC+) against right-handed pitching. He walked at a 14.4% clip when holding the platoon advantage and fanned at a higher-than-average but still-manageable 24.1% rate. Lefties have always had Choi’s number, however, and his overall production cratered in 2023 while he dealt with Achilles and ribcage injuries. He’s fighting for a bench spot in New York alongside DJ Stewart and others.

Nationals: RHP Matt Barnes, OF Eddie Rosario, OF Jesse Winker

Barnes was an All-Star closer with the Red Sox in 2021 and briefly one of the game’s most dominant relievers, fanning more than 40% of his opponents for the bulk of that season. He wore down beginning in August and hasn’t been the same since a hip injury. Barnes’ velocity and strikeouts were way down in 2023 before he underwent season-ending surgery. He should have a good chance to win a spot in a Nationals bullpen that has little established talent.

Rosario and Winker are both left-handed-hitting outfielders who are best deployed in left field — with Winker having a particularly shaky defensive reputation. Winker is the younger of the two at 30 years old (to Rosario’s 32). Winker was quietly one of the most productive hitters in baseball against right-handed pitching for much of his time in Cincinnati, but knee and neck surgery in October 2022 look to have taken their toll on him. Rosario was the far more productive hitter in 2023. There may not be room for both veterans on the Washington roster. Winker has been in camp longer and been more productive in their small samples.

Orioles: 2B Kolten Wong

The Orioles seem to bring in a veteran infielder coming off a down season almost every year. It’s Wong’s turn in 2023. The 33-year-old was one of the game’s worst hitters in ’23, slashing just .183/.256/.263 in 250 plate appearances between the Mariners and Dodgers. That was beyond out of character for Wong, who’d been an average or better hitter in five of the past six seasons. If the O’s don’t want to rush Jackson Holliday or Coby Mayo, Wong could win a spot on the roster — but he hasn’t hit that well in camp so far.

Pirates: RHP Chase Anderson

It’s been five years since Anderson’s last solid season in a big league rotation, but the well-liked veteran continues to get work each season. From 2020-23, he’s pitched to a 6.19 ERA in 192 MLB frames — including a 5.42 mark in 86 1/3 innings last year (mostly with the Rockies). Anderson doesn’t miss many bats, but he has good command and is having a nice spring with the Pirates. He’s competing with Luis Ortiz, Jared Jones, Roansy Contreras, Domingo German and others for one of two generally open rotation spots in Pittsburgh.

Rangers: INF Matt Duffy, RHP Shane Greene, RHP Jose Urena

A contact-oriented hitter who can play all over the infield, the 33-year-old Duffy faces an uphill battle with Josh Smith, Ezequiel Duran and Justin Foscue all on the 40-man roster ahead of him. Nathaniel Lowe will open the season on the injured list, but that’ll likely work to Jared Walsh’s benefit more than Duffy.

Greene, 35, is a former All-Star closer/setup man who peaked with the Tigers and Braves from 2017-20. He’s thrown just three innings in each of the past two MLB seasons but also turned in strong numbers with the Cubs in Triple-A last year.

The 32-year-old Urena made five dismal starts for the Rockies early in the 2023 season and five solid ones for the White Sox late in the season. He also pitched well for Chicago’s Triple-A affiliate. A solid arm for the Marlins in 2017-18, Urena has a 5.50 ERA in 350 1/3 MLB frames dating back to 2019. He’s had a nice spring and could be a depth piece for an injury-plagued Rangers rotation.

Rays: RHP Jake Odorizzi

Odorizzi signed last week and will look to get back on track after a shoulder injury cost him the 2023 season. With the exception of an injury-wrecked 2020 season, he’s been a dependable five-inning starter dating back to 2014 (3.98 ERA in 1216 innings). The Rays’ pitching staff is dealing with plenty of injuries, and Odorizzi should be an option for the Rays early in the season.

Red Sox: 1B C.J. Cron, RHP Michael Fulmer, C Roberto Perez, LHP Joely Rodriguez

Cron has four seasons of 25-plus homers under his belt and was consistently an above-average hitter from 2014-22. Injuries tanked his 2023 season, but he has a strong track record of hitting for power — with largely even platoon splits. He’d make a nice right-handed complement to Triston Casas and/or Masataka Yoshida at first base and designated hitter, providing some insurance against an injury to either.

Perez is an all-glove backup who’s never hit much outside the juiced ball season in 2019, when he popped 24 of his 55 career homers. The Sox figure to go with Reese McGuire and Connor Wong behind the plate, making him a long shot to land a roster spot.

Rodriguez signed a big league deal with the Red Sox prior to the 2023 season but only pitched 11 innings due to injury. He’s having a decent spring training — two runs on nine hits and three walks with nine strikeouts in seven innings — and has a good chance to win a spot in a patchwork Red Sox bullpen. If not, his ability to miss bats and pile up grounders would likely draw interest elsewhere.

Fulmer won’t pitch in 2024 after undergoing surgery last summer. His minor league deal is a two-year contract that stretches into 2025. The two sides knew this going into the arrangement and there’s no reason to expect he’ll opt out.

Royals: RHP Tyler Duffey

Duffey was a mainstay in the division-rival Twins’ bullpen and was a high-end setup option at his peak in 2019-21, posting a 2.89 ERA across 144 frames while fanning 29.8% of his opponents. His results slipped in 2022 as he lost some life on his fastball, and he pitched just two MLB frames with the Cubs in 2023. Duffey recently had a procedure to remove a cancerous mole from his shoulder that understandably halted his baseball activity for a bit. He’s hopeful he’ll pitch again this spring, and while the larger takeaway is relief that the melanoma was discovered and quickly treated, his track record could also give him a shot to crack the Royals’ bullpen early in the season.

White Sox: RHP Jesse Chavez, RHP Brad Keller, RHP Dominic Leone, 3B/1B Mike Moustakas, OF Kevin Pillar, RHP Bryan Shaw

Chavez, 40, has been excellent with the Braves in each of the past three seasons but struggled in stints with the Cubs and Angels. He’s having a tough spring with the White Sox but carries a 2.81 ERA in his past 137 2/3 MLB frames, spanning the 2021-23 seasons.

Keller has spent his entire big league career with the Royals but saw his time in Kansas City come to a rough ending. After a three-year run as a solid starter, Keller struggled in three subsequent seasons, culminating in an IL stint for symptoms indicative of thoracic outlet syndrome. He hasn’t pitched in an official spring game for the White Sox.

Leone struggled late in the 2023 season but has a cumulative 3.38 ERA in 157 innings over the past three seasons. He’s having a solid spring training, has late-inning experience, and seems like a decent bet to win a spot in a White Sox bullpen that’s been completely torn down since last summer.

Moustakas has turned in three straight below-average seasons at the plate and is struggling again with the White Sox in camp (.167/.268/.278 in 41 plate appearances). The Sox have Yoan Moncada and Andrew Vaughn at the corners, plus Gavin Sheets as a lefty-swinging first base option (and corner outfielder) off the bench. Moose seems like a long shot to make the club.

Pillar would give the Sox a right-handed complement to lefty-hitting corner outfielders Andrew Benintendi and Dominic Fletcher. He’s 35 and no longer the plus-plus defensive center fielder he once was but could give them some insurance for Luis Robert Jr. in center as well. He hit .228/.248/.416 with nine homers in 206 plate appearances for the Braves last year.

Shaw pitched 45 2/3 innings for the Sox last year and delivered a respectable 4.14 ERA in that time. His production has tailed off substantially since his days as a consistent setup presence in the Cleveland bullpen — evidenced by a 5.07 ERA over his past six seasons. He’s been tagged for a dozen earned runs in 7 1/3 spring frames but does have 10 strikeouts.

Rodriguez, 32, was with the Sox in 2023 but pitched just 11 innings due to oblique, shoulder and hip injuries that combined to result in three different stints on the injured list. He posted a 6.55 ERA in his short time on the mound, striking out 27.5% of his opponents against an 11.8% walk rate and 45.2% ground-ball rate.

It wasn’t a strong year overall for Rodriguez, but the lefty has posted far better numbers over the three preceding seasons in his return from an excellent two-year stint in Japan’s Nippon Professional Baseball. From 2020-22, Rodriguez pitched 109 1/3 frames between the Rangers, Yankees and Mets, working to a 4.28 ERA with even more encouraging secondary marks. Rodriguez fanned 25.5% of his opponents in that time and induced grounders at a huge 55.7% clip. His 10.3% walk rate was still a couple ticks north of the league average, but the lefty offered an enticing blend of missed bats and grounders while excelling at keeping the ball in the park (0.58 HR/9). Metrics like FIP (3.14) and SIERA (3.51) were rather bullish on his work.

The Red Sox have little in the way of established left-handed bullpen options on the 40-man roster. Brennan Bernardino surprised with 50 1/3 innings of 3.20 ERA ball as a 31-year-old rookie last season, but the only other southpaws on the roster are Joe Jacques and minor league starters Brandon Walter and Chris Murphy. Rodriguez joins Lucas Luetge as a veteran southpaw who’ll compete for a job in Alex Cora’s bullpen. With a healthy spring, he ought to have a decent chance at winning a spot in a bullpen that’s seen a fair bit of turnover this offseason in the wake of a front office shakeup.

The decision is hardly a surprising one, even though Rodriguez looked like an interesting pickup for Boston when he was signed to a $2MM guarantee last offseason. At the time of the signing, Rodriguez had spent the prior three seasons with the Rangers, Yankees, and Mets, pitching to a combined 4.28 ERA in 119 games with a sterling 3.14 FIP and a solid 25.5% strikeout rate. While those numbers indicated that the 31-year-old Rodriguez could be at least a solid middle reliever from the left side with perhaps even potential for a higher leverage role, that did not come to pass in 2023.

Instead of reaching the potential he has flashed in the past, Rodriguez suffered through an injury-marred season with the Red Sox this year. After starting the year on the injured list due to an oblique issue, Rodriguez then missed time with a shoulder strain and a recurring hip problem that eventually ended his season. All told, Rodriguez pitched just 11 innings for the Red Sox this year during which he allowed nine runs (eight earned) on 13 hits and six walks while striking out 14.

As Rodriguez returns to the open market, it’s certainly feasible that the lefty could be a quality bullpen arm for a club in 2024 if he manages to get healthy. That being said, between his lost 2023 campaign and past results that trended closer to average than the above-average production his underlying metrics might indicate, it seems likely that Rodriguez will be forced to settle for a minor league deal ahead of his age-32 campaign.

Looking toward the Red Sox, the bullpen in Boston is fairly well set up with Kenley Jansen and Chris Martin both returning for the late innings, not to mention the likes of Garrett Whitlock and Josh Winckowski. That said, with both Rodriguez and Richard Bleier headed to the open market this winter, it’s certainly reasonable to wonder if the club could look for another left-handed relief option to pair with Brennan Bernardino in the bullpen. The free agent market has plenty of options available in the regard, including veteran set-up arms like Matt Moore and Will Smith.

It has been an injury-marred year for Rodriguez, who has tossed only 11 innings in his first season in Boston.  The lefty signed a one-year free agent deal last winter worth $2MM in guaranteed money, yet he suffered a Grade 2 oblique strain during Spring Training that delayed his season debut until May 17.  Rodriguez then missed another month due to shoulder inflammation, returning to action on July 8 and appearing in six games before his latest IL stint.

There was quite a gulf in Rodriguez’s performance in between IL visits, as he had an ugly 18.00 ERA over his five games and four innings prior to his shoulder-related injury absence.  In July, however, Rodriguez was much sharper, with seven scoreless innings and no walks over the six appearances before his hip injury sent him to the sidelines.  It works out to a 6.55 ERA for the season, and Rodriguez might not get a chance to improve on that total if his hip problem does indeed result in a permanent shutdown.

Rodriguez’s contract contains a 2024 club option worth $4.25MM, or the Red Sox can buy out that option for $500K.  Given the string of injuries, it certainly doesn’t seem like Boston will exercise that option, so Rodriguez is likely to be headed back to free agency.  Entering his age-32 season and with an injury-riddled 2023 behind him, Rodriguez may have to settle for a minor league deal or another low-guarantee MLB contract on the open market this winter, even if he can make it back for a few more innings near the end of Boston’s season.

The Sox have been looking for left-handed relief options for much of the year due to Rodriguez’s frequent absences, but it seems as though they have landed on a pair of solid lefties in Brennan Bernardino and Chris Murphy.  The bullpen as a whole got another boost today when Garrett Whitlock was activated from the 15-day IL, and Whitlock threw two scoreless innings and picked up the win in Boston’s 6-3 victory over the Tigers.

It was Whitlock’s first outing since July 3 due to a bout of right elbow inflammation, and the Sox plan to use him as a multi-inning reliever rather than a starter.  Whitlock has been much more effective as a reliever than as a starter over the last three seasons, plus the Red Sox also have Tanner Houck lined up for starting duty when Houck returns from his own IL stint.  Cora told Browne and company that Houck is slated to make one more minor league rehab start before being activated from the IL next week.

Baltimore Orioles

• Mychal Givens: $6MM mutual option ($2MM buyout if team declines, $1MM buyout if player declines)

Givens has bounced around in journeyman fashion over the past few seasons. The middle reliever returned to his original stomping grounds in Baltimore on a $5MM free agent guarantee. He hasn’t had any chance to get into a rhythm yet, however. He opened the season on the injured list with left knee inflammation. He was out until late May and made four appearances, allowing six runs in four innings while working with diminished velocity. The O’s put him back on the IL last week, citing inflammation in his throwing shoulder.

Boston Red Sox

• Corey Kluber: $11MM club option (no buyout)

Kluber signed a $10MM free agent guarantee with Boston over the offseason. He’d been a reliable innings-eating veteran for the Rays last year. Kluber hasn’t been a Cy Young-caliber pitcher for quite some time, but Boston envisioned him as a stabilizing mid-rotation presence in a starting staff full of unproven or injury-riddled options.

It hasn’t worked out that way. Kluber was tagged for a 6.26 ERA through his first nine starts. His strikeout rate dropped to a career-worst 17.7% clip, and he served up home runs at an untenable 2.38 HR/9 pace. The Sox bumped Kluber out of the rotation two weeks ago, pushing him into multi-inning relief. He’s tossed three innings of two-run ball in his first bullpen appearances in a decade.

An injury to Chris Sale could get Kluber another rotation opportunity, but he’ll have to pitch much better than he did in the first two months of the season for the Sox to entertain an $11MM+ option. The option price would escalate by $500K if Kluber makes 20 starts and an additional $750K apiece at 25 and 30 starts (which look unlikely based on the bullpen move).

• Joely Rodríguez: $4.25MM club option ($500K buyout)

The Sox signed Rodríguez to a $2MM free agent deal at the beginning of last offseason. He suffered an oblique strain in Spring Training and was knocked out of commission for six weeks. The 31-year-old has returned to pitch in four games but surrendered nine runs. He went back on the 15-day IL over the weekend with shoulder inflammation. This appears on its way to a buyout.

• Richard Bleier: $3.75MM club option ($250K buyout)

Rodríguez isn’t the only veteran lefty reliever who’s battling injury problems. Bleier landed in Boston via a change-of-scenery bullpen swap that sent Matt Barnes to Miami. While the soft-tossing southpaw is inducing ground balls at a strong 51.5% clip, that’s below the career 61.5% grounder rate he carried into the year. He’s never missed bats. The 36-year-old is a grounder specialist with elite control. He’s been uncharacteristically prone to hard contact in his early stint in Boston, contributing to a 5.85 ERA through 20 innings. The Sox placed Bleier on the 15-day IL due to shoulder inflammation a couple weeks ago. It’s early but trending towards a buyout as well.

New York Yankees

• Josh Donaldson: $16MM mutual option ($6MM buyout if team declines)

Donaldson is playing out the final guaranteed season of the four-year free agent deal he signed with the Twins in 2020. The Yankees took on the contract in the 2022 trade that also brought in Isiah Kiner-Falefa. (That trade converted a ’24 club option into a mutual option.) It’s a move New York would like to have back, with both Kiner-Falefa and Donaldson underwhelming in the Bronx.

Donaldson, the 2015 AL MVP, had his worst offensive showing in a decade last year. He hit .222/.308/.374 over 546 plate appearances while striking out at a career-worst 27.1% rate. Public metrics still loved Donaldson’s defense at the hot corner. Despite some offseason speculation the Yankees could try to offload some of his contract, they didn’t seem to come close to finding a taker and opened this season with Donaldson back at third base. He played only five games before suffering a right hamstring injury that cost him almost two months. The Yankees activated him from the IL over the weekend, and he promptly hit two home runs in his return — followed by an 0-for-4.

With a hefty $6MM buyout, there’s only a $10MM net call on the option. That’s not an outlandish price for a solid everyday player, but Donaldson’s offensive drop-off, age, and recent injury history all raise questions about whether he should be a regular on a team with playoff aspirations. Barring a summer offensive outburst from the three-time All-Star, the team is probably buying this out.

Toronto Blue Jays

• Chad Green: Team has three-year, $27MM option (if declined, Green and team have conditional options)

Green signed a complex free agent deal as he works back from May ’22 Tommy John surgery. He’s making $2.25MM this year. At season’s end, the Jays will have to decide whether to trigger three consecutive $9MM options (essentially a three-year, $27MM contract for 2024-26). If the team declines, the right-hander would get a $6.25MM player option for next year only. If Green passes on that, the Jays would have to make a call on a two-year, $21MM option for 2024-25.

With a year removed from surgery, Green recently progressed to throwing batting practice (via MLB.com injury tracker). A post All-Star Break return to MLB action is on track. While guaranteeing Green $27MM based on a couple good months after Tommy John surgery seems unlikely, the Jays were at least open enough to the possibility to sign him to the contract in the first place. There haven’t been any notable setbacks in the four months since they put pen to paper.

• Whit Merrifield ($18MM mutual option, $500K buyout)

The Jays acquired Merrifield from the Royals last summer. It was a buy-low move while the former American League hits leader was scuffling, and he’s gotten on track north of the border. Merrifield has a .292/.339/.413 batting line as a Blue Jay. That includes a .299/.349/.399 showing in 2023 that has locked him in as Toronto’s starting second baseman.

While Toronto has gotten what they’d wanted from Merrifield, it’s hard to envision them exercising this option. The $17.5MM price point is lofty, particularly when considering the market has tended to devalue contact-oriented second basemen. The Phillies bought out a $17MM option on Jean Segura last winter, for instance; he found a $17MM guarantee spread over two years from the Marlins on the open market. The Brewers did exercise a $10MM option on Kolten Wong but promptly traded him to Seattle in a buy-low flier for Jesse Winker. An $8-12MM per-year salary for Merrifield is more reasonable, particularly when considering that he’ll turn 35 next January.

• Yimi García: $5MM club option ($1MM buyout); option vests at $6MM with 49 appearances or 49 innings pitched in 2023

García signed a two-year guarantee with a club/vesting option over the 2021-22 offseason. The option would vest at $6MM if he combines for 110 innings or 110 outings between 2022-23. García threw 61 innings in as many appearances last season, leaving 49 more to check off.

He’s well on his way to doing so. García has made 26 appearances and tossed 24 2/3 innings entering play Monday. He’s 23 outings or 24 1/3 frames shy of triggering the vesting provision. Unless the veteran righty sustains a notable injury, he should clear that threshold.

Even if García doesn’t vest the option, it’s not out of the question the Jays would bring him back. There’d be a $4MM difference between the club option price and the buyout. García was solid in year one, working to a 3.10 ERA with a 23.5% strikeout rate. A massive .368 average on balls in play has led to a 6.20 ERA thus far in 2023, but García’s peripherals are strong as ever. He’s striking out 26.5% of batters faced while inducing grounders on half the batted balls he allows. He’s averaging 96 mph on his heater. His ball in play results figure to stabilize.

Note: Austin Voth signed an arbitration contract that contained a 2024 club option. He’d remain eligible for arbitration next season even if the option is declined and has accordingly been excluded from this list.

Since Kansas City already seems out of the pennant race, that means Garrett should be able to return well before the trade deadline, and perhaps establish himself as a trade chip for a Royals team that is already open to moving relievers.  Garrett is a free agent this winter, making him even more of an obvious trade candidate as a rental player.  Beyond his current health issue, however, the biggest obstacle in the way of a Garrett deal is his garish 17.7% walk rate, the highest yet for a pitcher who has struggled with control over most of his seven MLB seasons.  While Garrett has only a 3.00 ERA over 21 innings and his strikeout (25%) and grounder (48.1%) rates are both respectable, the walk rate certainly stands out as a red flag for any interesting suitors.

More on other injury situations around baseball…

• Jose Altuve didn’t play today and likely won’t play on Sunday, as Astros manager Dusty Baker told reporters (including Danielle Lerner of the Houston Chronicle) that Altuve is dealing with a minor oblique problems.  The second baseman felt discomfort after a swing in Friday’s game, and while the injury isn’t deemed serious enough to merit an MRI, the Astros are naturally being careful with Altuve given how oblique problems can linger or become easily aggravated.  It’s a day-to-day situation for now, though Houston doesn’t have an off-day on the schedule until June 12.
• The Guardians removed Amed Rosario from today’s game in the fourth inning due to left knee soreness.  Rosario is day-to-day for now, and since Cleveland has an off-day on Monday, it seems very likely that Rosario will be sat for Sunday’s game to give him two full days to rest and recover.  Rosario has struggled badly this season, hitting only .224/.270/.314 over 226 plate appearances, and he has the fourth-lowest fWAR (-0.7) of any qualified player in 2023.  Any of Gabriel Arias, Tyler Freeman, or Brayan Rocchio could get more playing time at shortstop if Rosario has to miss an extended amount of time.
• Joely Rodriguez was warming up in preparation of entering tonight’s Rays/Red Sox game, but Sox manager Alex Cora told reporters (including Julian McWilliams of the Boston Globe) that Rodriguez had to halt his warmup due to soreness in his bicep and shoulder area.  More will be known once some tests are run, but it certainly looks like Rodriguez could be headed back to the IL.  An oblique injury in Spring Training already delayed Rodriguez’s season debut until May 17, and the left-hander has struggled to an 18.00 ERA over his four innings and five appearances.
• The Marlins told reporters (including Daniel Alvarez-Montes of El Extra Base) that Avisail Garcia’s rehab assignment has been temporarily halted, as he will receive examination on his sore back.  Garcia has already been on the IL since April 29 due to lower back tightness, so while the team described the setback as “minor,” it is a little worrisome to see Garcia further delayed.  The outfielder has played in four games with Triple-A Jacksonville during his rehab assignment.

10:12PM: The Red Sox have designated Ryan Brasier for assignment, as the right-hander himself told reporters (including Peter Abraham of the Boston Globe) tonight in the aftermath of a tough outing against the Cardinals.  Brasier allowed three runs over 2 1/3 innings of relief in a 9-1 Red Sox loss.

No corresponding move is yet known, though manager Alex Cora told reporters over the weekend that Joely Rodriguez was going to be activated from the 15-day injured list on Monday, so the Sox could be clearing room for Rodriguez’s return.  Rodriguez suffered a Grade 2 oblique strain in mid-March during Spring Training, and has yet to pitch this season.

Tonight’s performance inflated Brasier’s season ERA to 7.29 over 21 innings of work out of the Boston bullpen.  There is some level of misfortune in that ERA since Brasier’s strand rate (52.8%) and BABIP (.344) are both skewed, and his FIP is a more moderate 4.38.  That said, he has also posted below-average strikeout and walk rates, and Brasier is near the bottom of the league in hard contact.

The advanced metrics were much more favorable to Brasier last year, but the bottom-line results still weren’t there, as the righty had a 5.78 ERA over 62 1/3 innings in 2022.  With the lack of results stretching into a second season, the Sox have opted to part ways with a reliever who has had his share of ups and downs over six years in Boston, but for the most part was a solid hurler prior to the start of the 2022 season.

After pitching with the Hiroshima Toyo Carp in 2017, Brasier returned from Japan to sign a minor league deal with the Red Sox, and ended up unexpectedly emerging as an ace reliever for the eventual World Series champions.  Brasier posted a 1.60 ERA over 33 2/3 regular-season innings and then a 1.04 ERA in 8 1/3 postseason innings to help the Sox win the title.

Brasier’s 2019 season was a lot shakier, but he posted better results in 2020-21, with a 3.16 ERA albeit over only 37 innings.  Brasier’s workload was limited by the shortened 2020 regular season, and then a 2021 campaign that saw him miss most of the year due to a calf strain and then a concussion after he was struck in the head by a line drive during a simulated game.

The 35-year-old is in his final year of arbitration eligibility, and is still owed roughly $1.5MM of his $2MM salary for the 2023 season.  It doesn’t seem all that likely that another team will claim Brasier off DFA waivers, so the Red Sox will likely end up eating the salary if they end up releasing the righty, or they could simply outright him down to Triple-A.  If Brasier is signed by a new team after being released, the new club will only owe the prorated portion of the Major League minimum salary, with Boston covering the remainder of the $1.5MM.

Rodríguez, 31, was signed in the offseason to a one-year, $2MM deal with a club option for 2024. He spent last year with the Mets, posting a 4.47 ERA over 55 appearances. He walked 12% of batters faced but got strikeouts at a 26.4% rate and grounders at a 53.8% clip. It’s possible that he deserved better than that ERA indicates, as his .303 batting average on balls in play and his 63.3% strand rate were both on the unlucky side of average. His 3.23 FIP and 3.54 SIERA suggest he could be better if his luck were to even out.

Unfortunately, he will have to wait a while to test that luck with his new club, as he’s likely going to be out of action for a while. Though Cora wouldn’t provide any specifics on the estimated return timeline, there are some recent examples with more details. The Rays, for instance, gave an estimate of six-to-eight weeks when Tyler Glasnow recently suffered his own Grade 2 oblique strain. Every injury is different and it can’t simply be assumed that Rodriguez is looking at the same timeframe, but that can at least provide a rough guideline for what might be on the table here.

The Sox were set to have two lefties in their Opening Day bullpen, with Richard Bleier being the other. There are no other lefty relievers on the 40-man roster, but this news will perhaps open the door for someone else to make the club. Ryan Sherriff was signed to a minor league deal this offseason and could be an option. He was reassigned to minor league camp last week but this new info could perhaps increase his chances of making the club.

If the Sox are interested in external additions, the free agent market still features guys like Zack Britton and Ross Detwiler. It’s also possible that some new names will join them on the open market as Opening Day approaches and other clubs make their final roster decisions.
