Guerrieri, 28, had worked to a 4.61 ERA with a 22.6 percent strikeout rate against a 9.7 percent walk rate through 27 1/3 innings since joining the Mariners on a minor league deal. On the one hand, he’d scaled back his ERA considerably after a rocky start, holding opponents to just four runs in his past 14 1/3 innings. On the other hand, the strong strikeout and walk rates he posted early in Tacoma had swung the other direction; he’d punched out 12 hitters against nine walks and two hit batters in that stretch of 14 1/3 frames.

A former first-round pick of the Rays and longtime top pitching prospect, Guerrieri has faced multiple arm injuries over the course of a decade-long professional career — most notably Tommy John surgery that wiped out the majority of his 2013-14 seasons. He does have 36 MLB frames under his belt, split between the Blue Jays and Rangers, but he’s struggled to a 5.50 ERA with a 27-to-22 K/BB ratio in that time.

The 36-year-old Huff had some strong outings but lacked consistency, logging a 5.25 ERA in 48 innings with Tacoma. He’s never been a big strikeout arm, and that was the case in 2021 as well, punching out just 16.5 percent of his opponents, albeit against an excellent 4.5 percent walk rate.

Huff hasn’t pitched in the big leagues since 2016 but does have 393 1/3 MLB frames under his belt. The best of that work came from 2011-14, when he posted a 4.03 ERA in 174 innings split among three clubs (Indians, Yankees, Giants). Huff struggled in a short stint with the 2016 Halos but went on to carve out a nice career overseas, spending two years in the Korea Baseball Organization and another two in Nippon Professional Baseball in Japan. He returned to the U.S. and spent the 2020 season pitching independent ball.

Dull, 31, was a standout reliever with the A’s back in 2016 but has never managed to replicate anything close to the 2.42 ERA he logged through 74 1/3 innings that year. He’s posted a 6.08 mark in 80 MLB innings since that time and had been scuffling again in Triple-A this year, as evidenced by a 6.06 ERA in 35 2/3 innings. Dull started his time in Tacoma with five shutout innings and a 6-to-1 K/BB ratio, but he’s since been tagged for 26 runs (24 earned) in 30 2/3 innings.

Now 28 years old, Guerreri once ranked as one of baseball’s premier pitching prospects. The Rays selected him with the No. 24 overall pick back in 2011, and he was considered to be among the game’s 100 best prospects for the next three years.

As is the case so often with promising young hurlers, however, Guerrieri’s development was halted by Tommy John surgery. Guerrieri underwent that operation midway through the 2013 season and missed all of 2014 as a result. He’s battled other arm troubles since that time and, to this point in his career, has only topped 100 innings in a season on one occasion. He was healthy for the 2019 season, splitting the year between the Majors and Triple-A in a relief role with the Rangers.

Guerrieri tossed 28 1/3 innings with Texas that year and another 9 2/3 with the Blue Jays a year prior, but his results at the MLB level haven’t been impressive so far. In 36 frames, he’s been tagged for a 5.50 ERA with nearly as many walks (22) as strikeouts (27). However, Guerrieri was quite good with the Rangers’ Nashville affiliate in 2019, and he’s displayed elite spin on his curveball in limited big league action.

Chargois, 30, was a second-round pick by the Twins back in 2012 and at one point looked like he could be a future closer in Minnesota. He posted dominant minor league numbers with sizable strikeout rates and an upper-90s heater, but Chargois hasn’t yet found his footing in the big leagues. The Rice University product has just a 4.58 ERA in 76 2/3 MLB frames, though his 3.40 SIERA, 26.3 percent strikeout rate and 9.9 percent walk rate are a bit more encouraging. Chargois pitched with Japan’s Rakuten Eagles last year and struggled to a 5.81 ERA in 26 1/3 innings of work in that tiny sample, but he has a lengthy minor league track record of success — including a 1.90 ERA in 85 1/3 Triple-A frames.

Pelham, 24, boasts a blistering fastball that averaged better than 96 mph in his 2018 MLB debut, but the former 33rd-round pick struggled through a poor season in the upper minors in 2019. Pelham allowed 43 runs in 32 1/3 innings between Double-A and Triple-A this season and walked more batters (40) than he struck out (37).

The waiver claim is likely about the appealing nature of Pelham’s raw pitch arsenal, but there’s clearly an enormous amount of work to be done in order to refine the lefty. Still, with a pair of open spots on the 40-man roster, there’s little harm in placing a claim — and the Cubs could always try to pass Pelham through waivers themselves in order to keep him in the organization without committing a 40-man spot.

As for Guerrieri, he once ranked as one of the game’s premier pitching prospects in his days with the Tampa Bay organization, but injuries have largely derailed much of the promise he once showed. The 26-year-old (27 next week) posted a 5.68 ERA in 26 1/3 innings at the MLB level in 2019, although his 3.47 ERA, 9.7 K/9, 3.8 BB/9 and 55.7 percent grounder rate in Triple-A offer more encouragement.

Guerrieri entered the pro ranks as a first-rounder of the Rays in 2011, and he remained a high-end prospect for a little while after that. However, Guerrieri – also a former Blue Jay – could now be on his way to his fourth organization at the age of 26. While Guerrieri did pitch to a 3.47 ERA/3.33 FIP with 9.66 K/9 and 3.72 BB/9 in 36 1/3 innings as a member of the Rangers’ Triple-A affiliate in 2019, he logged a bloated 5.81 ERA/5.38 FIP and 9.23 K/9 against 7.52 BB/9 across 26 1/3 frames at the MLB level.

Pelham, 24, first joined the Rangers as a 33rd-round pick in 2015. He made a brief debut in the majors in 2018, though he threw all 32 1/3 of his innings between Double-A and Triple-A ball this year. The hard-throwing Pelham recorded an unsightly 11.97 ERA with more walks (40) than strikeouts (37) during that span.

As Evan Grant of the Dallas Morning News relays (via Twitter), Calhoun was rather blindsided by the move. “I’m speechless,” Calhoun said after learning of his demotion. “I’ve helped the team win. If me playing every day at Nashville helps team win, then I guess I have to play every day in Nashville.”

Calhoun has indeed been a generally productive bat with Texas, hitting .277/.313/.489 with five big flies in 99 plate appearances. At the same time, he’s struggled mightily to get on base in his latest stint with the team. Since being summoned from Nashville on June 17, Calhoun has homered three times and smacked four doubles in 75 PAs, but he’s also batted just .225/.267/.408 on the whole. He’s walked more than he’s punched out so far in Nashville in 2019, so perhaps a quick trip back down to the minors can help him to bring some of that approach to the MLB level.

That said, Calhoun also seems like a casualty of a roster that simply has too many outfielders at the moment. Delino DeShields Jr. is hitting .326/.377/.442 since his own recall from Triple-A. Joey Gallo (.266/.406/.626) has been sensational all season long. Pence (.294/.363/.608) and fellow veteran Shin-Soo Choo (.291/.389/.508) are both highly productive veterans. Nomar Mazara may not have lived up to his considerable prospect billing yet, but he’s outhit Calhoun over the past couple of months nonetheless (.276/.327/.454 in his past 40 games).

Calhoun seems likely to return in the event of an injury or trade elsewhere in the outfield, and it’s at least possible that the organization takes this demotion as an opportunity to continue getting him some work in the infield. Texas has reportedly been working Calhoun out at second base and even third base of late, and if that experiment continues into game settings in the minors, it’d only enhance his versatility at the MLB level. Calhoun does have extensive experience as a second baseman in the minors, but he was moved to the outfield due to defensive concerns.

As for Guerrieri, the former first-round pick (Rays, 2011) and top prospect will get his first shot with the Rangers after notching a 3.47 ERA, 9.7 K/9 and 3.7 BB/9 in 36 1/3 innings with the team’s Nashville affiliate. He did throw 9 2/3 frames with the Blue Jays in his first big league action last year, allowing five runs on nine hits and four walks with eight strikeouts.

• The Rangers culled their number of players in camp to 60. Pitchers Taylor Guerrieri, Michael Tonkin, Miguel Del Pozo and Brady Feigl were all assigned to minor league camp, per the Rangers’ executive VP of communications John Blake (via Twitter). Guerrieri, 26, joined the Rangers after making his major league debut last season with the Blue Jays. A former first round pick of the Rays, he was a starter in the minor leagues until missing most of the 2017 season due to injury. Toronto claimed him off waivers before last season, where started 7 games in Triple-A before appearing 9 times out of the Blue Jays pen, pitching to a 5.02 FIP in a small-sample 9 2/3 big league innings. Tonkin, 29, appeared in parts of five seasons for the Twins from 2013 to 2017 with a 4.57 FIP across 141 games. Del Pozo, 26, reached as far as Double-A in the Marlins system before joining the Rangers as a non-roster invitee. While Feigl, 28, is back in the Rangers system where he has pitched for the past two seasons.
• The Cubs made a number of roster moves today, with promising righties Adbert Alzolay and Jen-Ho Tseng being optioned to Triple-A, while Justin Steele and Oscar De La Cruz were sent to Double-A, per the Athletic’s Patrick Mooney (Twitter links). Also on the move, Duncan Robinson, Ian Clarkin, Colin Rea, Ian Rice, Charcer Burks and Jacob Hannemann are being moved to minor league camp (Twitter link). Mark Gonzales of the Chicago Tribune (via Twitter) adds Craig Brooks, Alberto Baldonado and Evan Marzilli to the list of players headed to minor league camp. The Cubs spring roster has now been cut to 54.
• Rob Scahill, meanwhile, was released outright by the Cubs, per Mooney (via Twitter). Scahill has pitched at the big league level for parts of seven seasons running, topping out at 31 appearances in 2016 spread between Milwaukee and Pittsburgh. In total, the 32-year-old boasts a career 3.95 ERA (4.67 FIP) in 124 games for Rockies, Pirates, Brewers and White Sox.

3:55pm: The Rangers are in agreement on a one-year, Major League contract with veteran right-handed reliever Zach McAllister, tweets Bob Nightengale of USA Today. The Excel Sports client will earn a $1MM salary in 2019, and Fancred’s Jon Heyman tweets that he can boost his earnings via an incentives package.

McAllister, 31, struggled through an awful 2018 campaign with the Indians and Tigers, posting a combined 6.20 ERA in 45 innings of relief between the two clubs. He did turn in a quality 39-to-10 K/BB ratio in that time, though, and McAllister’s 95.3 mph average fastball velocity was as strong as ever. Additionally, he actually made some gains in swinging-strike rate and particularly on his opponents’ chase rate on out-of-zone pitches.

It’s also worth noting that McAllister was a quality reliever for Cleveland from 2015-17, during which time he turned in a 2.99 ERA with 10.0 K/9 against 3.3 BB/9 through 183 1/3 innings of work. Texas has plenty of open spots in its relief corps behind closer Jose Leclerc and the re-signed Jesse Chavez, so it’s not all that surprising to see the organization add an affordable veteran arm. If McAllister can successfully rebound to his 2015-17 form, he’d presumably become a trade asset for the Rangers this summer.

The Rangers organization has yet to announce the move, but Texas did announce a trio of minor league signees today — right-handers Taylor Guerrieri and Michael Tonkin, as well as catcher Tony Sanchez. Each will be invited to Major League Spring Training. Tonkin’s addition was already covered here at MLBTR earlier this month.

Guerrieri, 26, made his MLB with the Blue Jays this past season but only appeared in nine games, totaling 9 2/3 innings with a 4.66 ERA (five runs allowed). A former first-round pick and top prospect with the Rays, Guerrieri’s career has been slowed by injury — most notably including Tommy John surgery in 2013. He’s also served a 50-game suspension in the minor leagues (for a “drug of abuse” as opposed to a performance-enhancing substance). Guerrieri has pitched to a 3.31 ERA in parts of two Double-A seasons (182 innings) but has not yet found much in the way of success in Triple-A or the Majors.

Sanchez, now 30 years of age, was a first-rounder himself back in ’09 but has appeared in just 52 big league games with a .257/.301/.375 slash to his name through 156 plate appearances. He’s a career .253/.340/.403 hitter in nearly 2000 Triple-A plate appearances, though, and he’ll give Texas some depth behind 40-man options that include Isiah Kiner-Falefa, Jeff Mathis and Jose Trevino. Jett Bandy, too, will be in camp with the Rangers as a non-roster invitee.

Shafer, 26, made his big league debut in ’18 but allowed three runs in 8 1/3 innings while issuing a troubling seven walks in that time. He struggled as a starter in the low minors but has posted solid ERA marks as a reliever in Double-A (2.75, 75 1/3 innings) and Triple-A (1.49 ERA, 42 1/3 innings). Shafer has still averaged under eight punchouts per nine innings and walked nearly four per nine innings in the upper minors, though.

Cruz, 32, has bounced around the league on minor league deals since he was a top pick in the 2011 Rule 5 Draft. He posted an ERA north of 6.00 in his rookie season with the Astros following that selection and has never found his footing in the big leagues, as he owns a 5.20 ERA in 79 2/3 frames.

Guerrieri was one of the top prospects in baseball with the Rays before arm injuries tanked his status. He posted video game numbers between Class-A Advanced and Double-A as a 22-year-old in 2015 but has yet to find success in the upper minors (4.86 ERA in 66 2/3 Triple-A innings) since making it back to the mound. He threw 9 2/3 innings with the Blue Jays this year and allowed five runs on nine hits and four walks with eight strikeouts.

Petricka has the most experience of the names in question here, and he posted a 4.53 ERA with a respectable 8.1 K/9 against 3.2 BB/9 in 45 2/3 frames out of the Toronto ’pen in 2018. The longtime White Sox reliever has a lifetime 3.98 ERA in 223 2/3 MLB frames but would’ve been arbitration-eligible this winter. The Blue Jays, rather than pay him a raise on 2018’s $1.3MM base salary, opted to cut him loose early and give him a jump start on finding a new club in free agency.

Arm troubles have persistently slowed the career of Guerrieri, a former first-round pick (No. 24 overall, 2011) that from 2012-14 was a consensus top 100 prospect in all of baseball. Guerrieri had Tommy John surgery back in 2013, which limited him to 9 1/3 frames the following season. He slowly built back up over the next two seasons, topping out at a career-high 146 1/3 innings at the Double-A level in 2016. However, further elbow complications limited Guerrieri to that exact same mark of 9 1/3 innings once again in 2017, though he didn’t require surgery this time around. Marc Topkin of the Tampa Bay Times tweets that Guerrieri is believed to be healthy and ready for Spring Training 2018.

Santos (27 in February) and Campos (30) made a handful of appearances each in Toronto this past season, totaling 31 1/3 innings between the two of them. While Santos posted a solid-looking 2.70 ERA in his 16 2/3 frames, he also walked four and served up four home runs in that time. He turned in a 4.07 ERA in 108 1/3 Triple-A innings, mostly as a starter. Campos, meanwhile, showed promising strikeout numbers but shakier control both in the Majors and minors — a common trend throughout his career.

Cole, 28, saw more limited action yet, missing most of the minor league season with an injury before going on a 12 2/3-inning scoreless streak and earning a late look in the Majors. He was hit hard in his lone MLB appearance and suffered a fractured toe after one inning, which cut short his chances of further auditioning.

Lopez, meanwhile, had a great season in Triple-A, hitting .293/.368/.551 in 223 plate appearances. The 30-year-old saw just 63 PAs with the Blue Jays late in the season, though, and has never established himself in the Majors to this point in his career (nor has he demonstrated the level of offensive prowess he did at Buffalo this season).

In brief: players drafted/signed at 18 years of age or younger must be added to the 40-man roster within five years of signing or be exposed to the Rule 5 Draft. Players drafted/signed at 19 or older must be added within four years. Those interested in all of the specifics can refer to articles from MLB.com’s Jonathan Mayo and J.J. Cooper of Baseball America. Perhaps of greater interest is that Mayo lists all of the prospects from MLB.com’s Top 100 list and from their organizational Top 30 lists that much be protected in advance of tonight’s deadline, while Cooper provides brief write-ups on each player that has been protected (and will continue to do so as additions are made).

Here are today’s additions to the 40-man roster. You can check out Baseball America’s coverage to learn more about the individual players listed below …

• The last team to report is the Giants, who have added a host of names to their 40-man: pitchers Ty Blach, Clayton Blackburn, Kyle Crick, Ian Gardeck, Adalberto Mejia, Steven Okert, Jake Smith, and Chris Stratton. With the roster filled up with that many pre-MLB arms, it’s fair to wonder whether the team anticipates trading from among that group.
• In their second set of 40-man promotions today, the Astros have selected the contracts of outfielder Andrew Aplin and infielder Nolan Fontana.
• Moving onto the Marlins 40-man are lefty Jarlin Garcia and a trio of righties: Jacob Esch, Austin Brice, and Nick Wittgren.
• The Cubs have placed backstop Willson Contreras, righty Pierce Johnson, third baseman Jeimer Candelario, and first baseman Dan Vogelbach onto their 40-man, the team announced.
• The Phillies added outfielder Roman Quinn and righties Jimmy Cordero and Edubray Ramos.
• Joining the Royals’ 40-man are pitchers Matthew Strahm, Alec Mills, and Kyle Zimmer, infielder Ramon Torres, and outfielders Brett Eibner and Bubba Starling, the club announced.
• The Rockies have selected the contracts of righties Carlos Estevez and Antonio Senzatela, infielder Trevor Story, and outfielder Raimel Tapia.
• The Rays will add righties Jacob Faria, Taylor Guerrieri, and German Marquez to the 40-man roster along with infielder/outfielder Taylor Motter and rising lefty prospect Blake Snell.
• The Pirates have added top prospects Tyler Glasnow and Josh Bell to the club’s 40-man, along with fellow youngsters Harold Ramirez (an outfielder) and Max Moroff (a middle infielder).
• Righty Victor Alcantara has been placed on the Angels’ 40-man, the club announced. As MLB.com’s Alden Gonzalez notes on Twitter, Alcantara is probably now the team’s single best prospect.

Earlier Updates

• Joining the big league side of the roster for the Yankees are righties Johnny Barbato and Rookie Davis along with outfielder Ben Gamel, the team announced.
• The Reds announced the additions of right-handers Robert Stephenson, Sal Romano, and Stephen Johnson to the 40-man roster to keep them from Rule 5 eligibility.
• Going onto the Rangers’ 40-man roster are outfielder Nomar Mazara, lefty Yohander Mendez, and righties Jose Leclerc and Connor Sadzeck.
• The Dodgers brought righties Jharel Cotton and Ross Stripling onto their 40-man, per a team announcement.
• Infielder Marco Hernandez, righty Pat Light, and lefty Williams Jerez are the newest members of the Red Sox 40-man, the club announced.
• The White Sox have protected righties Brandon Brennan and J.B. Wendelken from the Rule 5 by giving them roster spots.
• The Orioles have added a trio of pitchers, per an announcement. Parker Bridwell and Andrew Triggs throw from the right side, while Chris Lee is a southpaw.
• Moving onto the 40-man for the Indians are righties Mike Clevinger, Shawn Morimando and Dylan Baker, as well as outfielders Tyler Naquin and James Ramsey, per the club.
• The Mets announced the additions of outfielder Brandon Nimmo and righties Seth Lugo, Jeff Walters, and Robert Gsellman to the club’s major league roster.
• Second baseman Joey Wendle and left-hander Jose Torres were added to the Athletics 40-man roster, per the club.
• The Mariners announced that they have purchased the contracts of infielder Patrick Kivlehan and outfielder Boog Powell, thereby adding them to the 40-man roster and protecting them from the Rule 5 Draft.
• The Astros announced the additions of catcher Alfredo Gonzalez and right-handers Jandel Gustave, Juan Minaya, Joe Musgrove and David Paulino to the 40-man roster. Notably, Gustave was a Rule 5 pick last year and found himself with both the Padres and Royals before ultimately being returned to Houston.
• The Tigers announced that they’ve added right-handers Michael Fulmer and Montreal Robertson as well as left-hander Jairo Labourt to the 40-man. Fulmer was the main piece picked up in Detroit’s trade of Yoenis Cespedes, while Labourt was one of three lefties acquired from Toronto in the David Price trade.

By parting with Arencibia, the club appears to have chosen to keep Rene Rivera around behind the dish, as Marc Topkin of the Tampa Bay Times tweets. The 29-year-old Arencibia still benefited from his time in Tampa Bay, though, as he put on a power show in his 73 plate appearances and figures to have boosted his free agent stock. Nava, soon to turn 33, never really got going last year and will probably be left looking for an opportunity on a minor league deal this winter.

On the pitching side of the ledger, the 31-year-old Gomes has seen his share of action in the Rays’ pen over the last five years, throwing a total of 167 innings of 4.20 ERA ball. He could land an MLB deal with a team looking for reliever depth. As for Yates, the 28-year-old righty was hit hard last year, but will enter the market with 10.1 K/9 vs. 3.5 BB/9 on his ledger over 56 1/3 career MLB innings.

Notably, also, the move will save Tampa Bay some money. MLBTR projected Arencibia ($1.4MM), Nava ($1.9MM), and Gomes ($900K) to command salaries that are not insignificant for a team with Tampa Bay’s tight payroll.

• The Athletics could exercise Brett Anderson's $8MM option for 2014 and then trade him to one of a few teams who are interested, with the Blue Jays being specifically cited, Susan Slusser of the San Francisco Chronicle writes.  Toronto scouted Anderson late last season and have been interested in the southpaw for the last two years.  Anderson has appeared in just 54 games over the last four seasons due to several injuries, most notably Tommy John surgery, so it would be a risky move for the injury-plagued Jays to acquire another pitcher with a poor health history.
• Rajai Davis is looking forward to his first free agent experience, the outfielder tells MLB.com's Gregor Chisholm.  Davis is looking for an everyday job and has historically struggled against right-handed pitching, which Chisholm notes makes it unlikely that the Blue Jays will re-sign him.
• Both Major League Baseball and Alex Rodriguez's camp have admitted to paying to obtain documents from the Biogenesis clinic, sources familiar to the Rodriguez appeal hearing tell Ken Davidoff of the New York Post.
• Rays right-hander Taylor Guerrieri has been suspended for 50 games for a PED violation, the league announced Friday.  Guerrieri twice tested positive for a "drug of abuse" that is believed to be marijuana, according to Marc Topkin of the Tampa Bay Times.  Guerrieri was the 24th overall pick of the 2011 draft and was considered one of the top prospects in baseball by MLB.com (44th-best), ESPN's Keith Law (#47) and Baseball America (#64) in preseason rankings.  The 20-year-old won't miss any game action due to the suspension since he was already slated to miss most of the 2014 season while recovering from Tommy John surgery.
• In AL East news from earlier today, the Yankees are reportedly planning to spend $300MM on new contracts this offseason while the Red Sox have agreed to sign Cuban right-hander Dalier Hinojosa to a minor league deal.

• Rays pitching prospect Taylor Guerrieri underwent Tommy John surgery today, Marc Topkin of the Tampa Bay Times reports. Drafted 24th overall by the Rays in 2011, Guerrieri is ranked as the 64th prospect in baseball by Baseball America. ESPN.com's Keith Law ranks him 47th, while Jonathan Mayo of MLB.com has him at No. 44. In 67 innings this year for the Rays' Class A affiliate, the right-hander had compiled a 2.01 ERA with 6.9 K/9 and 1.6 BB/9.
• Red Sox CEO Larry Lucchino says his team has an obligation to be active at the trade deadline, but that doesn't mean a deal is a certainty, Brian MacPherson of the Providence Journal tweets. While the Sox have been a popular name in trade speculation and have been connected with arms such as the White Sox's Jake Peavy and the Royals' Luke Hochevar, the executive cautions that the team isn't "just building for one year." "There's going to have to be a pretty good deal to extract some of these high-quality prospects we have," Lucchino said (link).
• The Orioles are getting lots of interest in Chris Dickerson and we can expect to see him in the majors somewhere in the next few days, tweets Britt Ghiroli of MLB.com.  The O's designated the outfielder for assignment last week.
