Tigers Sign Four Pitchers To Minor League Deals

By Anthony Franco | December 19, 2025 at 9:35am CDT

December 19th: Guenther will make $787K if he cracks the roster, per Petzold.

December 18th: The Tigers have made a handful of depth additions in the past few days. Relievers Jack Little and Sean Guenther return on minor league contracts after being non-tendered, according to the MLB.com transaction tracker. They’re adding left-hander Enmanuel De Jesus on a minor league deal that’d pay him at a $1.3MM rate if he makes the big league roster, reports Evan Petzold of The Detroit Free-Press. Righty reliever Cole Waites will also be in camp as a non-roster invitee after signing a minor league deal last week, as first reported by Ari Alexander of 7 News Boston.

Guenther is the only of the four pitchers who has appeared in a game for the Tigers. The left-hander has pitched 31 1/3 innings of 2.30 ERA ball over the past two seasons. He didn’t miss enough bats to support the excellent run prevention mark and has been an up-and-down middle reliever. Guenther missed the final three months of the ’25 season working back from hip surgery. Detroit used the non-tender deadline to drop him from the 40-man roster with an eye towards bringing him back on a minor league contract.

They did the same thing with Little, whom they’d claimed off waivers from Pittsburgh a couple weeks earlier. The 27-year-old righty (28 in January) debuted with two appearances for the Dodgers this year. He spent the rest of the season in Triple-A, where he turned in a 4.06 ERA with a modest 20.2% strikeout percentage over 62 innings.

De Jesus, 29, returns to affiliated ball after two seasons in Korea. He spent a year apiece with the Kiwoom Heroes and the KT Wiz. De Jesus worked out of the rotation and posted a sub-4.00 ERA while starting 30 games in both seasons. He struck out 24% of opponents with a 3.81 earned run average in 335 combined frames. The Venezuela native pitched in two MLB games for the Marlins in 2023.

Waites also most recently appeared in the big leagues two years ago. He allowed seven runs in eight innings for the Giants between 2022-23. He underwent elbow surgery late in the ’23 season and has missed most of the past two seasons. The 27-year-old Waites owns a 4.46 ERA in 43 career appearances at the Triple-A level.

American League Non-Tenders: 11/21/25

By Anthony Franco | November 21, 2025 at 4:22pm CDT

Every American League team has officially announced their non-tender decisions. It was a quiet evening in terms of subtractions, with only the Rangers parting with any marquee players. All players who were non-tendered are free agents without going on waivers. A few teams dropped pre-arbitration players from the back of the 40-man roster. It’s possible they preferred not to expose them to waivers and are hopeful of re-signing them to non-roster deals.

Here’s a full list of today’s activity in the AL, while the National League moves are available here. All projected salaries are courtesy of MLBTR contributor Matt Swartz.

  • The Angels announced they’ve non-tendered outfielder Gustavo Campero and catcher Sebastian Rivero. Campero is a depth outfielder who has hit .202/.272/.346 over the past two seasons. Rivero operated as the club’s third catcher for most of the season but spent the final few weeks on the active roster. Neither player had been eligible for arbitration. All their arb-eligible players were easy calls to retain.
  • The Astros technically made one non-tender, dropping infielder Ramón Urías after he was designated for assignment earlier in the week. He’d been projected at $4.4MM.
  • The Athletics officially non-tendered outfielder JJ Bleday, the club announced. He’d been designated for assignment on Tuesday, so this was inevitable unless they found a trade partner. Bleday had been projected at $2.2MM.
  • The only non-tenders for the Red Sox were first baseman Nathaniel Lowe and reliever Josh Winckowski, each of whom had been designated for assignment on Tuesday. Lowe was projected at $13.5MM, while Winckowski was at $800K.
  • The Guardians non-tendered outfielder Will Brennan and relievers Sam Hentges and Nic Enright. The latter had been designated for assignment on Tuesday. Hentges hasn’t pitched since undergoing shoulder surgery in September 2024. He underwent a right knee procedure a few months ago and will be delayed this offseason. Brennan only appeared in six MLB games this year and underwent Tommy John surgery while in the minors in June. He’d been projected at $900K.
  • The Mariners non-tendered reliever Gregory Santos, reports Francys Romero. He’d only been projected at $800K, narrowly above the MLB minimum, so the move was about dropping him from the 40-man roster. Seattle acquired the 26-year-old righty from the White Sox over the 2023-24 offseason. He has only made 16 MLB appearances with a 5.02 earned run average over the past two years because of lat and knee injuries. Seattle also non-tendered relievers Trent Thornton and Tayler Saucedo (the latter of whom was designated for assignment on Tuesday). Thornton had been projected at $2.5MM and is coming off a 4.68 ERA through 33 appearances. He suffered a season-ending Achilles tear in August.
  • The Orioles non-tendered swingman Albert Suárez, the team announced. Everyone else in their arbitration class was offered a contract, surprisingly including first baseman Ryan Mountcastle (as first reported by ESPN’s Jeff Passan). Suárez, 36, was a solid depth starter in 2024. He was limited to five MLB appearances this past season by a flexor strain but is not expected to require surgery.
  • The Rangers non-tendered each of Adolis García, Jonah Heim, Josh Sborz and Jacob Webb. MLBTR covered those moves in greater detail.
  • The Rays only non-tendered outfielders Christopher Morel and Jake Fraley, each of whom had been designated for assignment earlier in the week. Marc Topkin of The Tampa Bay Times reported last night that the Rays were open to bringing back Fraley at a lower price than his $3.6MM arbitration projection.
  • The Royals non-tendered outfielder MJ Melendez and reliever Taylor Clarke, per a club announcement. Melendez, who’d been projected at $2.65MM, was an obvious decision. The former top prospect never developed as hoped and is a career .215/.297/.388 hitter over parts of four seasons. Clarke isn’t as big a name but comes as the more surprising cut. He’d been projected at just $1.9MM and is coming off a 3.25 ERA with a 21.4% strikeout rate over 55 1/3 innings out of the bullpen.
  • The Tigers are non-tendering utility player Andy Ibáñez, according to Romero. He’d been projected at $1.8MM. The righty-hitting Ibáñez had been a solid short-side platoon bat for Detroit between 2023-24. His production against southpaws dropped this year (.258/.311/.403), limiting his value. The Tigers optioned the 32-year-old to Triple-A in early June and kept him in the minors until shortly before the trade deadline. Detroit also dropped the six pitchers they’d designated for assignment earlier in the week: Tanner Rainey, Dugan Darnell, Tyler Mattison, Jason Foley, Jack Little and Sean Guenther.
  • The only Twins non-tender was outfielder DaShawn Keirsey Jr., who’d been designated for assignment this morning to make room for the Alex Jackson trade. Everyone in the arbitration class was brought back.
  • The White Sox non-tendered outfielder Mike Tauchman, as first reported by Bruce Levine of 670 The Score. The lefty hitter turned in a solid .263/.356/.400 line in 93 games this past season. Tauchman has gotten on base at plus rates in three straight years but was also non-tendered by the Cubs a year ago. The 34-year-old (35 next month) had been projected for a $3.4MM salary. The Sox also announced they’ve dropped lefty reliever Cam Booser and first baseman Tim Elko. Neither had been eligible for arbitration. The former posted a 5.52 ERA in 39 appearances after being acquired from the Red Sox last winter, while the latter hit .134 in his first 23 MLB games despite a 26-homer season in Triple-A.
  • The Yankees announced five non-tenders. Relievers Mark Leiter Jr., Scott Effross, Jake Cousins and Ian Hamilton were all cut loose, as was pre-arbitration righty Michael Arias. Leiter, who’d been projected at $3MM, never clicked in the Bronx after being acquired at the 2024 deadline. He posted a 4.89 ERA in 70 innings as a Yankee. Hamilton, Effross and Cousins were all projected just above the MLB minimum but are cut to clear roster space. Hamilton was on and off the active roster and posted a 4.28 ERA in 40 big league frames this year. Effross was limited to 11 appearances and has been plagued by various injuries for the past three and a half years, while Cousins is working back from Tommy John surgery. Arias has never pitched in the big leagues and could be brought back on a minor league deal.

The Blue Jays tendered contracts to all unsigned players on the 40-man roster.

Tigers Designate Six Relievers For Assignment

By Anthony Franco | November 18, 2025 at 5:09pm CDT

The Tigers designated six relief pitchers for assignment: Dugan Darnell, Jack Little, Sean Guenther, Jason Foley, Tanner Rainey and Tyler Mattison. They added five prospects to the roster to keep them out of the Rule 5 draft: Hao-Yu Lee, Thayron Liranzo, Trei Cruz, Eduardo Valencia and Jake Miller. The sixth roster spot is filled by Gleyber Torres, who officially accepted the qualifying offer.

Liranzo, 22, isn’t too far removed from being one of the better catching prospects in the game. The Tigers landed him alongside Trey Sweeney in the 2024 deadline deal that sent Jack Flaherty to Los Angeles. He’d posted a .378 on-base percentage that season but dropped to a .206/.308/.351 slash line in 88 games with Double-A Erie this year. The Tigers weren’t going to jump ship after one bad year, but he may need to repeat Double-A.

Lee, a 22-year-old infielder out of Taiwan, came over from Philadelphia in the 2023 Michael Lorenzen deadline trade. He spent the entire season at Triple-A Toledo, where he hit .243/.342/.406 across 579 trips to the dish. He walked at a strong 11.2% clip while striking out 21% of the time. Lee can’t play shortstop and isn’t going to have a path to second base playing time behind Torres. His best chance of carving out MLB playing time in 2026 comes at third base.

Cruz gets a 40-man spot for the first time going into his age-27 season. The Tigers had left the former third-round pick unprotected in the past two offseasons. The switch-hitting infielder, the son of former big league outfielder José Cruz, earned his way onto the roster with a breakout year in the upper minors. Cruz hit .279/.411/.456 while leading all minor league hitters with 102 walks between the top two levels. The Rice product can play both left side infield positions and has the athleticism to play some center field.

Valencia is a 25-year-old catcher/first baseman who posted a monster .311/.382/.559 slash line between Erie and Toledo. He blasted 24 home runs while keeping his strikeout rate around 20%. The Venezuela native has never been viewed as much of a prospect, but the offensive performance in the high minors was too much to ignore.

Miller, a 24-year-old lefty, ranked 16th in the Detroit system at MLB Pipeline. An eighth-round pick in 2022 out of Valparaiso, he has shown an intriguing three-pitch mix with enough command and deception to project as a starter. Miller was limited to six starts between High-A and Double-A this year by a back injury, but Detroit likes him enough to keep him as a developmental play. He should begin next season in Erie.

Getting all those players onto the roster required cutting most of their depth relievers. Little and Darnell were just claimed off waivers. Detroit knew they’d be likely non-tenders but could try to bring them back on minor league deals. That’s also the case for Mattison, whom they kept out of the Rule 5 draft last winter but who had a middling year in the minors. Guenther has been up and down for the past couple seasons and missed the second half of 2025 recovering from hip surgery.

Rainey is a journeyman righty who cracked Detroit’s big league bullpen in the final week of the season. He’s narrowly shy of six years of service and therefore could have been retained via arbitration. MLBTR contributor Matt Swartz projected a modest $1.2MM salary, but Rainey is looking at minor league deals as a free agent.

Foley was probably the toughest cut. He’d been a valuable late-innings arm between 2021-24, a run which he capped off by saving 28 games last year. Foley missed all of ’25 recovering from shoulder surgery, and he would have been set to match this year’s $3.15MM salary if they tendered him a contract. They opted not to do so and are likely to cut him loose on Friday, though they have the next few days to see if there’s any trade interest.

Evan Petzold of The Detroit Free-Press first reported the Cruz, Valencia and Miller additions.

Tigers Select PJ Poulin

By Nick Deeds | July 6, 2025 at 11:03am CDT

The Tigers announced a pair of roster moves this morning. They’ve selected the contract of left-hander PJ Poulin to the 40-man roster and optioned him to Triple-A Toledo. Left-hander Sean Guenther was recalled from Triple-A and placed on the 60-day injured list to make room for Poulin on the 40-man roster. According to Evan Woodbery of MLive, Poulin had an upward mobility clause in his contract and the Tigers opted to add him to their 40-man roster in order to keep him in their organization.

Poulin, 29 later this month, was an 11th-round pick by the Rockies back in 2018. A two-way player in college, Poulin committed to pitching upon his move to affiliated ball. He looked quite good in the lower minors as a reliever in his first two years as a professional, but the canceled minor league season in 2020 lost him a year of development and he generally struggled with his effectiveness in the upper minors during his time with the Rockies organization.

He was dealt to the Tigers prior to the 2024 season and has looked quite good since then, as he posted a 2.10 ERA in 60 innings between Double- and Triple-A last year before posting a 3.72 ERA in 36 1/3 frames at Triple-A this season. That solid but unspectacular ERA comes with a much more impressive 33.8% strikeout rate, and that kind of strikeout stuff from the left side makes it easy to see why the Tigers decided it was worth it to add the lefty to their 40-man roster rather than risk losing him to another organization.

Making room for Poulin on the 40-man roster is Guenther, who has a 2.30 ERA and 2.73 FIP across 31 1/3 innings of work with the Tigers over the past two seasons. Guenther was on the shelf in the minors after undergoing hip surgery last week, meaning that the move to place him on the 60-day IL is largely a procedural one. With that being said, it does come with the side effect of allowing him to collect a big league salary and earn MLB service time until he’s activated and optioned back to the minor leagues.

Tigers Option Jace Jung

By Nick Deeds | March 17, 2025 at 8:02am CDT

In their latest round of Spring Training roster moves ahead of Opening Day, the Tigers announced this morning that they’ve optioned infielder Jace Jung and left-hander Sean Guenther. Neither player will break camp with the club.

Jung, 24, was the club’s first-round pick in the 2022 draft and is a former top-100 prospect. The youngster made his big league debut last year and hit a decent .241/.362/.304 (102 wRC+) in 94 trips to the plate for the Tigers, though that league average production is inflated by good fortune. While Jung walked at an excellent 16% clip during his time in the majors last year, the combination of a massive 30.9% strikeout rate and minimal power (just five extra-base hits, all of which were doubles) left him to rely on an unsustainable .380 BABIP to get his slash line to league average overall.

Even so, Jung entered camp as the likely favorite for an Opening Day job at third base for the Tigers. While the club made a serious push to add Alex Bregman to the mix in free agency this winter, they ultimately came up short and entered camp with only their internal options available to them. That put Jung in strong position to potentially earn the nod, but Jung has struggled badly in Spring Training this year as he’s gone just 4-for-33 at the plate with four walks against ten strikeouts. Spring Training numbers only count for so much, of course, but between his questionable cup of coffee last year and the Tigers’ over reliance on left-handed bats in the lineup the club clearly felt most comfortable sending Jung to Triple-A Toledo to begin the season.

With Jung now out of the mix for the Opening Day roster, third base seems likely to be manned by a platoon of the lefty-swinging utility man Zach McKinstry and righty bat Andy Ibanez. Ibanez was already expected to platoon with Jung entering camp, though McKinstry seemed ticketed for a bench role to start the spring. McKinstry hit just .215/.277/.337 (75 wRC+) in 325 trips to the plate for the Tigers last year but posted a slightly more robust .225/.284/.356 (82 wRC+) line against right-handed pitching last year. Ibanez, meanwhile, crushes left-handed pitching to the tune of a .292/.357/.445 slash line. McKinstry isn’t the only option to share time at third base with Ibanez, though none of Ryan Kreidler, Javier Baez, or non-roster invitee Jahmai Jones are necessarily surefire improvements over the utility man’s expected offensive production.

With Jung off the roster, that opens up a spot in the position player mix for one of the other players vying for a spot in camp. Cutting Jones makes shortstop Trey Sweeney very likely to break camp with the club, and the soon-to-be 25-year-old shortstop figures to platoon with Baez at short to open the year. At least one roster spot appears likely to go to either Spencer Torkelson or Justyn-Henry Malloy to offer the Tigers an additional right-handed bat in the outfield and DH mix while Matt Vierling is on the injured list, and the club’s final available spot on the bench figures to come down to one of Kreidler, Jones, and whichever of Torkelson and Malloy isn’t already on the roster.

As for Guenther, the cut isn’t exactly a surprise. The southpaw excelled in limited work last year with the Tigers, posting a 0.86 ERA and 2.60 FIP in 21 innings, but Tyler Holton and Brant Hurter both entered camp with a leg up on Guenther for an Opening Day roster job and the club signed veteran southpaw Andrew Chafin as a non-roster invitee during camp, which likely extinguished any hope of Guenther making the roster as a third southpaw in the bullpen.

Tigers Select Brant Hurter

By Nick Deeds | August 4, 2024 at 10:03am CDT

TODAY: The Tigers have officially announced the selection of Hurter’s contract. Left-hander Sean Guenther was optioned to Triple-A to make room for Hurter on the active roster.

AUGUST 3: The Tigers are planning to select left-hander Brant Hurter to pitch in tomorrow’s game against the Royals, AJ Hinch told reporters (including The Athletic’s Cody Stavenhagen) earlier this afternoon. Hurter is not yet on the 40-man roster, but the Tigers still have a space open after shipping Mark Canha, Jack Flaherty, and Andrew Chafin out on the day of the trade deadline so a corresponding move will only be necessary to add the southpaw to the club’s active roster.

Hurter, 26 in September, was a seventh-round pick by the Tigers in the 2021 draft out of Georgia Tech. Hurter reached the Double-A level in his first professional season back in 2022 and went on to dominate the level in 2023, with a 3.28 ERA in 118 innings of work across 26 starts. He struck out an impressive 26.7% of batters faced while walking just 6.6%, but the lefty has not been able to carry that success in Double-A over to his first taste of Triple-A action this year. In 19 appearances (18 starts) at the highest level of the minors in 2024, Hurter has been lit up to the tune of a 5.80 ERA in 71 1/3 innings of work. His strikeout rate has dropped to 21.7% while his walk rate has crept up slightly to 7.1%. Perhaps more notably, Hurter has struggled to keep the ball in the park as often as he did last year, allowing more home runs already this year than he did last year despite a nearly 50-inning gap in terms of volume.

As he prepares for his MLB debut tomorrow, Stavenhagen notes that Hinch made clear that he will not be starting the game and will instead act as a bulk arm following an opener. While Hurter has generally been used as a typical starter in the minors to this point in his career, he did have some success as a bulk pitcher earlier this year, when he threw six scoreless innings at Triple-A against the Reds’ Louisville affiliate after coming in as a reliever in the third inning.

With a rotation mix that currently features only four pitchers (Tarik Skubal, Kenta Maeda, Bryan Sammons, and Keider Montero), it would hardly be a surprise if a strong showing from Hurter tomorrow earned him a more extended look in the majors as the club tries to piece together a rotation, whether that be in a proper starting role going forward or simply as a bulk arm. The club’s rotation depth took a massive hit in recent weeks between the deal that shipped Flaherty to L.A. and recent injuries to Reese Olson, Casey Mize, and Matt Manning. There was some suggestion prior to the All-Star break that right-hander Beau Brieske could be considered for a rotation role in the second half, though that has not yet come to pass as he’s remained in a multi-inning relief role out of the bullpen.

Tigers Select Brenan Hanifee, Sean Guenther

By Darragh McDonald | August 1, 2024 at 2:45pm CDT

The Tigers announced they have selected the contracts of right-hander Brenan Hanifee and left-hander Sean Guenther. They also reinstated shortstop Javier Báez from the medical emergency/bereavement list. They will take the open roster spots of Jack Flaherty, Mark Canha and Andrew Chafin, who were all traded away on deadline day. Evan Woodbery of MLive Media Group relayed the news about Hanifee on X prior to the official announcement. Chris McCosky of the Detroit News relayed Guenther’s selected earlier on X.

Hanifee, 26, got a brief look in the majors last year. The Tigers selected his contract in September and he tossed five innings over three appearances, allowing three earned runs. He was non-tendered at the end of the season but then re-signed with the club on a minor league deal.

This year, he has tossed 47 innings over 34 Triple-A appearances. He has allowed 5.17 earned runs per nine innings but he has likely deserved much better. His 26% strikeout rate, 6.9% walk rate and 56.1% ground ball this year are all strong marks. If it weren’t for a .315 batting average on balls in play and 61.6% strand rate, which are both on the unlucky side, fewer runs would have crossed the plate. His 3.86 FIP is more than a run better than his ERA and perhaps a better reflection of his performance this year.

With the trades of Flaherty and Chafin, as well as recent injuries to Reese Olson, Casey Mize and Matt Manning, the Tigers could have some rope for Hanifee, especially since he’s been averaging more than an inning per appearance in Triple-A this year. He still has a full slate of options and just a few days of service time, so he could stick around on their roster for a while if the Tigers so choose.

Guenther, 28, made 14 appearances for the Marlins in 2021 with a 9.30 ERA. He underwent Tommy John surgery in April of 2022 and spent that entire season on the injured list before being claimed off waivers by the Tigers in November. He was outrighted off the roster shortly thereafter and has been with the Tigers in a non-roster capacity for almost two years now.

He has thrown 95 minor league innings in that time with a 3.69 ERA, 26.9% strikeout rate, 6.5% walk rate. He had a 47.1% ground ball rate at Triple-A last year and has a 55.5% rate at that level this year. Like Hanifee, he has a full slate of options but his service time clock is over the one-year mark, due to spending all of 2022 on the IL.

Tigers Announce Several Roster Moves

By Darragh McDonald and Steve Adams | November 15, 2022 at 5:10pm CDT

The Tigers announced several roster moves in advance of tonight’s Rule 5 protection deadline. Five players have been added to the 40-man roster: right-handers Reese Olson and Brendan White, infielders Andre Lipcius and Wenceel Perez, as well as outfielder Parker Meadows. In corresponding moves, they designated righties Miguel Diaz and Kyle Funkhouser, catcher Michael Papierski and outfielder Brendon Davis for assignment. Lefty Sean Guenther cleared waivers and has been outrighted to Triple-A Toledo.

Funkhouser, 29 in March, showed some promise in 2021 with a 3.42 ERA over 68 1/3 innings for the Tigers. Unfortunately, a shoulder strain kept him from pitching at any point in 2022. The right-hander was the No. 35 pick by the Dodgers back in 2015 but, as a player who slid after initially being a projected as top-ten or even top-five talent, returned to Louisville for his senior season. A poor year caused him to slide to the Tigers in the fourth round, and he’s now seen his pro career slowed by multiple shoulder injuries. In 85 2/3 career innings, he has a 4.20 ERA and a 12.9% walk rate.

Diaz, 28 later this month, had some success with the Padres in 2021 and pitched 3 2/3 innings of one-run ball with the Tigers in 2022. The bulk of his ’22 campaign, however, was spent in Triple-A Toledo, where he logged a 4.29 ERA with a 24.2% strikeout rate and 10.5% walk rate. Diaz throws fairly hard, averaging just shy of 96 mph on his heater, but his ability to miss bats has been inconsistent in the Majors, whereas his sub-par command has been a steady component of his game.

The 26-year-old Papierski has bounced around the league in 2022, spending time with the Astros, Giants, Reds and Tigers so far this calendar year. He hit .143/.228/.187 in 103 plate appearances this season, his Major League debut, and carries a .241/.361/.371 batting line in 160 games at the Triple-A level.

Davis, whom the Tigers claimed off waivers from the Angels back in May, made his big league debut in 2022 and went 2-for-10 with a walk in 11 plate appearances. The 25-year-old is a career .253/.352/.465 hitter in 721 plate appearances at the Triple-A level and has experience at shortstop, second base, third base and in both outfield corners.

Tigers Claim Sean Guenther From Marlins

By Darragh McDonald | November 2, 2022 at 1:45pm CDT

The Tigers announced that they have claimed left-hander Sean Guenther off waivers from the Marlins. He was on the 60-day injured list and remains there for now. Additionally, the Marlins have outrighted right-hander Paul Campbell and lefty Jake Fishman, per Jordan McPherson of the Miami Herald.

At this time of year, many teams are facing roster crunches with no injured list between the World Series and Spring Training. Players on the 60-day IL, like Guenther, don’t count against a team’s 40-man count but will soon need to retake spots. Furthermore, the deadline for adding players to the roster in order to protect them from being selected in the Rule 5 draft is November 15. Given those pressures, some teams are trying to proactively clear some space in anticipation of those upcoming choke points. It seems that the Marlins placed these three hurlers on waivers in recent days, losing one of them to Detroit.

Guenther, 27 in December, missed the entire 2022 season after undergoing Tommy John surgery in April. Given the general 12-18 month recovery time for TJS, he’ll miss at least part of the 2023 season as well but could return for a portion of it. He made his MLB debut in 2021 and put up an unfortunate 9.30 ERA in 20 1/3 innings. He was much better in the minors, however, as he tossed 40 1/3 innings with a 3.12 ERA, 34% strikeout rate, 4.4% walk rate and 47.2% ground ball rate.

Those are certainly intriguing numbers, even if he has yet to translate them to the big leagues. It makes sense for the Tigers to be interested, especially since he’s not currently costing them a roster spot. However, as mentioned, the IL will be going away in a few days. Given the large number of injuries suffered by Tigers this year, Roster Resource currently counts 48 guys on the 40-man roster, with that number factoring in free agency departures. It’s possible that Guenther ends up back on waivers again in a few days, alongside several other Tigers. If he were to pass through unclaimed at that point, the Tigers would be able to keep him around as depth without him taking up a roster spot.

Campbell, 27, was drafted by the Rays but went to the Marlins in the 2020 Rule 5 draft. In 2021, he missed time after being given an 80-game PED suspension, with Campbell issuing a statement refuting the results of the test. He eventually returned and finished the season with a 6.41 ERA over 26 2/3 innings. In 2022, he was placed on the IL in April due to an elbow strain and never returned. He can stick around the Marlins’ organization as a depth arm without occupying a roster spot.

Fishman, 28 in February, was on and off the Marlins roster this year. He was selected to the roster on three separate occasions, with the first two both resulting in a DFA after a few days, followed by clearing waivers and being outrighted. He managed to throw 11 MLB innings with a 4.09 ERA, while also tossing 56 frames in Triple-A with a 2.25 ERA, 23.1% strikeout rate, 8.5% walk rate and 54.2% ground ball rate. Due to the fact that he’s been previously outrighted in his career, he has the right to reject this assignment and elect free agency, though it’s unclear whether he’s chosen to do so or not.

Marlins’ Sean Guenther Undergoes Tommy John Surgery

By Anthony Franco | April 8, 2022 at 1:54pm CDT

The Marlins informed reporters this afternoon that left-hander Sean Guenther underwent Tommy John surgery yesterday (via Jordan McPherson of the Miami Herald). That’ll obviously keep him out for the entire season, and it seems likely he’ll miss a good portion of the 2023 campaign.

It’s a difficult blow for Guenther, albeit not all that unexpected. It was reported last week the southpaw was dealing with an arm issue which may require surgery. Miami had already placed him on the 60-day injured list, so there won’t be any forthcoming transaction now that he’s gone under the knife.

Guenther, 26, reached the big leagues for the first time last season. He made 14 appearances and worked 20 1/3 innings, struggling to a 9.30 ERA. Guenther didn’t miss many bats in the majors, but he induced grounders at a decent 47.2% clip. He also posted some excellent strikeout and walk numbers with Triple-A Jacksonville, where he punched out 30.1% of batters faced and only walked 4.3% of opponents.

While he won’t pitch in 2022, Guenther will receive major league pay and service time for his time on the IL. The Marlins will have to add him back to the 40-man roster at the start of next offseason.
