Albert Suárez Has Opt-Out In Deal With Orioles
Right-hander Albert Suárez is in camp with the Orioles on a minor league deal. He can opt out of that pact at the end of spring training if not added to the roster, reports Andy Kostka of The Baltimore Banner. Kostka adds that teams are keeping tabs on Suárez and his status as that opt-out decision approaches.
Suárez, 36, spent 2019 to 2023 putting up good numbers in Japan and Korea. He returned to Major League Baseball in 2024 by signing with the Orioles and went on to have his best big league season to date. He gave the O’s 133 2/3 innings in a swing role, making 24 starts and eight relief appearances. He allowed 3.70 earned runs per nine with a 19.1% strikeout rate and 7.6% walk rate.
He wasn’t able to repeat that performance last year. He was beset by a subscapularis strain and a mild flexor strain, only making five appearances on the year. He was non-tendered at season’s end and re-signed to a minor league deal. He has a 7.59 ERA in a small sample of four appearances in Grapefruit League play this spring.
It doesn’t appear as though he has a great path to a roster spot with the Orioles right now. They currently have a rotation consisting of Trevor Rogers, Kyle Bradish, Shane Baz, Chris Bassitt, Zach Eflin and Dean Kremer. They could option Kremer but it feels a bit unlikely since he’s been in the rotation for most of the past five years.
Assuming those six guys are on the roster, that leaves rooms for seven more pitchers, given the roster limit of 13 arms. Ryan Helsley, Keegan Akin, Dietrich Enns and Rico Garcia can’t be optioned. Yennier Cano and Tyler Wells have optioned but Kostka describes them as locks for the roster. Kostka also suggests Grant Wolfram is likely to get a spot as well.
That would be seven and would result in Jackson Kowar, who is out of options, getting squeezed out. Kowar has big velocity but hasn’t translated that into strong results yet. He has an 8.21 ERA in 91 big league innings.
It’s possible one spot could be opened if Eflin requires a stint on the injured list, though he seems to be trending towards avoiding the IL. If one spot does open up, Kostka suggests that it could go to Kowar or Suárez, though he also lists José Espada and Yaramil Hiraldo as possibilities. Those latter two guys have options and pretty limited big league experience. If the O’s want to maintain some depth, they could option them while using a spot to either select Suárez or keep Kowar.
With less than a week left in camp, decisions will need to be made soon, unless Eflin’s progress slows down or someone else gets hurt. Depending on how things play out in the coming days, it’s possible both Suárez and Kowar end up available to other clubs, Suárez via his opt-out and Kowar via waivers.

Orioles Acquire Jackson Kowar
The Orioles have acquired right-hander Jackson Kowar from the Twins in exchange for cash considerations, according to Roch Kubatko of MASN. The team placed fellow right-hander Colin Selby on the 60-day injured list with right shoulder inflammation in a corresponding move. Both teams have announced the move.
Kowar was designated for assignment by the Twins on Thursday. Prior to that, he had only recently been claimed off waivers from the Mariners. Kowar spent most of 2025 shuttling back and forth from Triple-A, though he did make 15 appearances (17 innings) at the big-league level. He had a 4.24 ERA in that sample, along with a 21.1% strikeout rate and a 9.9% walk rate. Kowar’s expected stats were more pessimistic, with his 5.15 xERA and 5.84 FIP suggesting he benefited from good luck.
Since his debut in 2021, Kowar has thrown 91 innings over 54 appearances (eight starts) between the Royals and Mariners. Unfortunately, he owns an unsightly 8.21 ERA in that time, with his expected numbers putting him in the upper-5.00s. His 20.3% strikeout rate is serviceable, but the righty has struggled with control to the tune of a 13.1% career walk rate. He also struggles to keep the ball in the yard, having allowed 19 home runs throughout his career (1.88 HR/9). Injuries certainly haven’t helped his performance. In March 2024, he suffered a torn ulnar collateral ligament and underwent Tommy John surgery while with the Mariners. Though he returned in May 2025, he missed the last month and a half of the season with a right shoulder impingement.
Kowar makes for an interesting low-cost flier for the Orioles’ bullpen mix. Statcast graded his fastball velocity in the 90th percentile and valued the pitch at two runs above average in 2025. Unsurprisingly, Kowar leaned on the pitch 57.7% of the time. The key for him will be improving his location and avoiding hard contact, as hitters slugged .476 against the pitch in 2025. His mid-80s slider was his second most-used pitch could be a plus pitch going forward. While it had a -1 run value this year, Kowar struck out 39.1% of hitters on that pitch. He has less than three years of service time and is out of options, so the club would need to pass him through waivers if he doesn’t make the roster.
Recent reports indicated that Selby was dealing with shoulder inflammation. He’ll now open the season on the injured list and will stay there until at least late May. Selby was acquired from the Royals in a July 2024 cash trade. He has thrown 18 big-league innings for Baltimore since then, 14 of them coming in 2025. In that small sample, he impressed with a 3.21 ERA and a microscopic 3.3% walk rate (which was admittedly an outlier from his career numbers). Selby’s sinker, slider, and knuckle curve all graded slightly above average in terms of run value. He has less than a year of service time and is also out of options, so he’ll need to perform well upon his return or else risk being placed on outright waivers.

Dodgers Trade Anthony Banda To Twins
1:17pm: The Twins sent $500K of pool space to the Dodgers in the deal, per Francys Romero of BeisbolFR.com. (International pool space must be traded in $250K increments.) For clarity’s sake, no actual money exchanged hands; rather, the Twins shrunk their league-allotted spending limit by $500K, while the Dodgers’ limit correspondingly increases by $500K.
12:27pm: The Twins have acquired veteran left-hander Anthony Banda from the Dodgers, per announcements from both clubs. Minnesota is sending international bonus space back to L.A. in return. Banda had been designated for assignment by the Dodgers last week. Righty Jackson Kowar has been designated for assignment to open a 40-man spot for Banda.
The Dodgers originally acquired Banda, now 32, in a cash deal early in the 2024 season. He quickly emerged as a quality bullpen option for them and spent the next season-plus as a frequently used southpaw for manager Dave Roberts. From 2024-25 in L.A., Banda logged a tidy 3.14 ERA with a 23.3% strikeout rate, 10.9% walk rate and 41.6% ground-ball rate. He averaged 96 mph on both his four-seamer and sinker while recording a 13.2% swinging-strike rate that suggests he could have a few more punchouts in the tank. Banda tallied 19 holds and two saves in 114 2/3 innings as a Dodger.
Banda’s 2025 season, however, wasn’t as sharp as his 2024 campaign. He lost a percentage point off his strikeout rate while his walk rate climbed by four points, from 8.6% to 12.7%. He still notched a 3.18 ERA in a career-high 65 innings, but his rate stats understandably gave the Dodgers some cause for concern.
The discrepancy between the bullpens in Los Angeles and Minnesota is underscored by the fact that this trade came together. The Dodgers deemed Banda expendable and jettisoned him and his $1.625MM salary. The Twins, meanwhile, traded some actual value to acquire him and will now count him among the most reliable arms in a bullpen that was torn all the way down at last year’s trade deadline. Minnesota traded five relievers — Jhoan Duran, Griffin Jax, Louis Varland, Brock Stewart and Danny Coulombe — dismantling what had been one of the league’s top relief units in order to scale back payroll and bring in some more controllable and affordable young talent in the process.
Where Banda was near the bottom of the pecking order in the L.A. bullpen, he now figures to be an option in high-leverage spots. That’s all the more true given his familiarity with new Twins skipper Derek Shelton, who managed Banda as a member of the Pirates back in 2021-22.
If Banda pans out in Minnesota, he can provide value to the Twins for multiple seasons. He currently has 4.135 years of MLB service, meaning he’ll be controllable through the 2027 season. He’ll be eligible for a raise in arbitration next winter, but his modest $1.625MM salary for the 2026 season means he won’t break the bank regardless of how well he pitches in what’ll be his debut campaign for Minnesota.
Banda joins the re-signed Taylor Rogers, Justin Topa and Cole Sands as the only members of the Twins’ bullpen with even three years of major league experience. The Twins also picked up righty Eric Orze in a small trade with the Rays early in the winter, and they got good work out of southpaw Kody Funderburk following that July fire sale in the bullpen (0.75 ERA, 28-to-10 K/BB ratio in 24 innings).
Veterans Liam Hendriks and Julian Merryweather joined up on minor league deals just yesterday and could factor into the group, as could any young starters who don’t crack a relatively crowded rotation picture. Pablo Lopez, Joe Ryan, Bailey Ober and out-of-options Simeon Woods Richardson all seem like rotation locks, health permitting. Former top prospects Taj Bradley, David Festa, Zebby Matthews and Mick Abel are among the candidates who’ll vie for the fifth spot (and possibly the fourth, if Woods Richardson is outpitched and heads to the bullpen himself).
Twins general manager Jeremy Zoll has been on the lookout for bullpen help throughout camp, and it wouldn’t be a surprise to see him further add to a perilously thin group of relievers in the days or weeks to come.
Kowar, 29, was claimed off waivers from the Mariners just eight days ago. The former first-round pick and top prospect has been derailed by injuries in his career but sits in the upper 90s with his four-seamer and sinker. He’s shown the ability to miss bats at times but struggles with sub-par command and too much hard contact allowed.
In parts of four MLB seasons (91 innings) between the Royals (his original club) and Mariners, the former Florida Gators star has been rocked for an 8.21 ERA. He posted a more palatable 4.24 ERA in 17 innings with Seattle last year, however, and notched a sharp 2.81 ERA in an additional 16 innings of Triple-A ball.
Kowar is out of minor league options. The Twins will hope to pass him through waivers and retain him as bullpen depth who’d be invited to big league camp and potentially stashed in the upper minors. If another club claims him, Kowar would need to stick on that team’s 40-man roster or else once again be exposed to waivers. The Twins can trade Kowar or place him on waivers at any point in the next five days. Waivers are a 48-hour process, so within a week’s time, we’ll know the outcome of Kowar’s DFA.
Dan Hayes of The Athletic first reported the trade and the Kowar DFA.
Twins Claim Jackson Kowar
The Twins have claimed right-hander Jackson Kowar off waivers from the Mariners, according to announcements from both clubs. Seattle had designated him for assignment a week ago when they acquired catcher Jhonny Pereda from the Twins. Minnesota had an open 40-man roster spot for Kowar thanks to trading Edouard Julien to the Rockies last week.
There’s a little bit of musical chairs happening here. The Twins recently signed catcher Victor Caratini and lefty Taylor Rogers, meaning they needed to open two roster spots. They designated Pereda and righty Pierson Ohl for assignment. They traded Pereda to Seattle, which nudged Kowar into DFA limbo. The Twins then traded both Ohl and Julien to the Rockies, getting a minor leaguer and cash while dropping their 40-man count to 39. They have now used that open roster spot to claim Kowar.
The 29-year-old Kowar has big velocity, averaging in the upper 90s with his four-seamer and sinker, but hasn’t yet translated that into major league success. He has 91 big league innings under his belt, split between the Royals and Mariners, allowing 8.21 earned runs per nine. He has walked 13.1% of batters faced, somewhat normal for guys with big heat, but has only punched out 20.3% of opponents. He hasn’t had much success in Triple-A either, with a 4.92 ERA at that level.
Seattle burned Kowar’s final option in 2025, so he is now out of options. Since he hasn’t been able to put up good numbers in the majors or the minors, he got nudged off the roster. For the Twins, they had a roster spot open and they also have huge bullpen questions. As part of their deadline fire sale last year, they traded away Jhoan Duran, Griffin Jax, Louis Varland, Danny Coulombe and Brock Stewart.
They are planning to return to contention in 2026 but haven’t done much to reload the relief corps. Apart from signing the 35-year-old Rogers, their biggest move has been to acquire Eric Orze, who has just 35 big league appearances.
Kowar is a wild card but the big velo is a nice starting point, even if he hasn’t harnessed it yet. He has landed with a club that should have lots of opportunities available. But given his out-of-options status and poor numbers, it’s possible the Twins try to pass him through waivers in the future. He doesn’t have a previous career outright nor three years of big league service time, so he wouldn’t have the right to reject an outright assignment.

Mariners Designate Jackson Kowar For Assignment
The Mariners announced they’ve designated reliever Jackson Kowar for assignment. That opens a 40-man roster spot for catcher Jhonny Pereda, whom they acquired from the Twins in exchange for cash considerations. Minnesota had designated Pereda for assignment last week when they signed free agent catcher Victor Caratini to a two-year contract.
Kowar, 29, is a former supplemental first-round pick of the Royals. He allowed 79 runs in 74 innings over parts of three seasons with Kansas City. They swapped him to the Braves for injured starter Kyle Wright over the 2023-24 offseason. Kowar’s time with the organization lasted less than a month, as the Braves flipped him to Seattle as part of the multi-player deal that sent Jarred Kelenic to Atlanta.
It was a change-of-scenery sequence involving a number of former high draft picks, but none of the players involved performed as hoped. Kowar blew out during his first Spring Training as a member of the Mariners. He underwent Tommy John surgery and was out of action until May ’25. He was on and off the active roster for the next few months until suffering a season-ending shoulder impingement in August.
Kowar has ultimately made just 15 appearances in a Seattle uniform. He allowed eight runs over 17 innings, walking seven while recording 15 strikeouts. The Florida product gave up nine runs (five earned) across 16 Triple-A innings. He has an 8.21 earned run average with a 20.3% strikeout rate and elevated 13.1% walk percentage across 91 MLB innings.
Primarily a fastball-changeup pitcher earlier in his career, Kowar cut back on the change while ramping up his slider usage last season. It resulted in a few more whiffs in his Triple-A time, though his control remains an issue. He sits around 97 MPH with the fastball and could intrigue teams based on the arm speed and his draft pedigree despite the grisly MLB numbers. He’s out of options, so he’d need to break camp or again be designated for assignment if another team is willing to give him an offseason 40-man spot.
Pereda is a well-traveled depth catcher who has divided his 48 major league games between three teams. He debuted with 20 appearances for the Marlins two seasons ago and combined for 28 games between the A’s and Minnesota last year. The 29-year-old (30 in April) has hit .241 without a home run in 118 major league plate appearances. He has a strong upper minors track record, batting .296/.392/.419 in just shy of 1000 career Triple-A plate appearances.
The Venezuelan-born Pereda has a good arm and a generally solid defensive reputation. He also has a minor league option, so the M’s can send him back to Triple-A for the 2026 season. They signed Andrew Knizner to a $1MM free agent deal to work behind Cal Raleigh. Trading Harry Ford had left them without any other catchers on the 40-man roster. Pereda has a leg up on non-roster invitee Nick Raposo as the top depth option in case either of their MLB catchers suffer an injury. Knizner is a career .211/.281/.316 hitter, so it’s not out of the question that Pereda outplays him for the backup job during the season.
Mariners Select Sauryn Lao
The Mariners announced a series of roster moves today, including the previously-reported reinstatement of Bryce Miller from the 15-day injured list. They also selected the contract of fellow righty Sauryn Lao. To open active roster spots for those two, righties Jackson Kowar and Casey Legumina were both optioned to Triple-A Tacoma. To open a 40-man spot for Lao, righty Trent Thornton has been transferred to the 60-day injured list.
Last night, Seattle starter Logan Gilbert had a surprisingly rough start. He lasted only two innings against the Phillies but not before allowing six runs. To get through the rest of the game, the M’s got three innings from Carlos Vargas, two from Legumina and one from Kowar. Legumina tossed 38 pitches and Kowar 30.
Miller is starting tonight and it’s unclear how much length he can give. He has been on the IL for over two months due to elbow inflammation. He got to 5 2/3 innings and 76 pitches in his most recent rehab start. It’s possible he could give the M’s something like that tonight but there’s also some natural uncertainty. To freshen up the bullpen behind Miller, the M’s have sent out Kowar and Legumina to bring in Lao.
Lao was selected to the roster in April. He got to make his major league debut on April 22nd, tossing one and two thirds scoreless innings. He was optioned to the minors the next day and designated for assignment a week later. He cleared outright waivers, allowing the Mariners to bring him back in a non-roster capacity.
Interestingly, the M’s have been stretching him out in Triple-A, even though he’s primarily been a reliever throughout his career. He has thrown 66 innings over 21 appearances this year with a flat earned run average of 3.00. He has struck out 26.3% of batters faced while limiting walks to a 6.7% clip. That should allow him to provide the M’s with multiple innings of relief, if needed.
As for Thornton, it was reported a couple of weeks ago that he is done for the season due to a torn left Achilles tendon. He will be spending the rest of the year on the IL. He is making $2MM in 2025 and could be retained for 2026 via arbitration. However, given his health uncertainty, it’s entirely possible the Mariners decide to non-tender him.

Mariners Reinstate Jackson Kowar, Option Logan Evans
The Mariners announced that right-hander Jackson Kowar has been reinstated from the 60-day injured list. The 40-man roster had a vacancy due to right-hander Jesse Hahn being designated for assignment last week but is now full. To open an active roster spot, righty Logan Evans has been optioned to Triple-A Tacoma.
Kowar, 28, has been with the Mariners for over a year but will be making his team debut whenever he gets into a game. He was acquired from Atlanta in December of 2023 but required Tommy John surgery in March of 2024. He spent all of last year and the first few months of this year on the IL.
Prior to going under the knife, he had shown promise with a recent change in role. A starter for most of his career, he showed a velocity bump while moving to a relief role in 2023. He had averaged around 95.7 miles per hour with his fastball as a starter but got that up to 97 mph out of the bullpen. The results didn’t immediately click, as he had a 6.43 earned run average that year, as well as subpar strikeout and walk rates of 21.2% and 14.6%.
Still, the M’s clearly feel there are good ingredients to work with. After the Royals flipped Kowar to Atlanta as part of the Kyle Wright deal, the M’s grabbed him as part of the Jarred Kelenic deal. They kept him on the roster throughout the winter, when there’s no IL, so they’re surely hoping their patience will pay off now that he’s healthy.
Evans got called up about a month ago, making his major league debut as the M’s dealt with various rotation injuries. He generally performed well, with a 2.83 ERA over six starts. Looking under the hood, there are some less impressive numbers, such as a 17.4% strikeout rate. But as far as injury replacements go, the M’s have to be thrilled with what Evans gave them.
The rotation has been getting healthier of late. George Kirby is now off the IL. It seems like Bryce Miller and Logan Gilbert are nearing returns as well. The M’s could therefore have their ideal quintet shortly, with Luis Castillo and Bryan Woo the other two pieces. Evans has been bumped into a depth role for now, while Emerson Hancock could be next.

Mariners Claim Seth Martinez
The Mariners announced that right-hander Seth Martinez was claimed off waivers from the Marlins. Righty Jackson Kowar was placed on the 60-day injured list in Seattle’s corresponding roster move.
Miami designated Martinez for assignment earlier this week, and today’s move makes it four different organizations in a little under four months’ time for the 30-year-old reliever. After spending his first four MLB seasons with the Astros, Martinez was designated for assignment in early November and claimed by the Diamondbacks. He then went to the Marlins on another waiver claim on February 20 before being DFA’ed again a week later, and now Martinez finds himself back in the AL West.
Martinez is out of minor league options, which somewhat explains his carousel of an offseason. With teams prizing flexibility within their bullpens, Martinez’s status makes him something of the proverbial 26th man, while also still having enough value that several teams are interested in having him on their rosters.
Over 111 appearances and 137 1/3 innings with Houston, Martinez often worked as a multi-inning reliever, so the Mariners would deploy him in that same capacity if he ends up on the Opening Day roster. Martinez has a career 3.93 ERA, though his strikeout rate fell rather sharply from 23.1% in 2023 to just 16.2% last season. Between that dropoff and other uninspiring Statcast metrics, the Astros felt comfortable in exposing Martinez to DFA waivers, leading to his busy winter of changing teams.
An innings-eating reliever always carries some usefulness, even on a Mariners team with an unusually durable starting rotation. A good Spring Training performance might help Martinez break camp with the team, or he might find himself on the waiver wire yet again before Opening Day.
Kowar underwent a Tommy John surgery almost exactly one year ago, so he was expected to miss some time at the start of the 2025 season as he finishes up his rehab. The 60-day IL placement means that Kowar won’t make his 2025 debut until late May at the earliest.
Players Who Could Move To The 60-Day IL Once Spring Training Begins
Most of the clubs in the league currently have a full 40-man roster, which means that just about every transaction requires a corresponding move these days. Some extra roster flexibility is on the way, however. The 60-day injured list goes away five days after the World Series but comes back when pitchers and catchers report to spring training.
Per R.J. Anderson of CBS Sports, most clubs have a report date of February 12th or 13th. The Cubs and Dodgers are a bit earlier than most, on the 9th and 11th, respectively. That’s due to the fact that those clubs are heading to Tokyo, with exhibition games in mid-March, followed by regular season games against each other on March 18th and 19th. All the other teams have Opening Day scheduled for March 27th.
It’s worth pointing out that the 60 days don’t start being counted until Opening Day. Although a team can transfer a player to the 60-day IL quite soon, they will likely only do so if they aren’t expecting the player back until end of May or later. A team also must have a full 40-man roster in order to move a player to the 60-day IL.
There are still plenty of free agents still out there, including big names like Alex Bregman and Pete Alonso, as well as Nick Pivetta, Andrew Heaney, David Robertson, Randal Grichuk, Kenley Jansen, Harrison Bader, Lance Lynn, Jose Quintana and many more. Perhaps the extra roster flexibility will spur some deals to come together in the next week or so. It could also increase the ability of some clubs to make waiver claims or small trades for players who have been designated for assignment.
Here are some players who are expected to miss some significant time and could find themselves transferred soon.
Angels: Robert Stephenson
Stephenson underwent a hybrid Tommy John surgery with internal brace in late April. Given the 14-plus months required to recovery from such a procedure, he’s not likely to be ready in the early parts of the 2025 season.
Astros: Cristian Javier, J.P. France, Bennett Sousa
Javier underwent Tommy John surgery in June and is targeting a return in the second half of 2025. France is recovering from shoulder surgery and hoping to return in July. Sousa’s timeline is less clear but he underwent surgery for thoracic outlet syndrome in April. Other possibilities include Luis Garcia and Lance McCullers Jr., who are expected to start the season on the IL but returning in April or May still seems possible.
Athletics: Luis Medina, Ken Waldichuk
Medina underwent Tommy John surgery in August and Waldichuk in May. Medina might miss the entire season while Waldichuk is likely to miss a few months at least.
Blue Jays: Angel Bastardo, Alek Manoah
The Jays grabbed Bastardo from the Red Sox in the Rule 5 draft in December, even though he had Tommy John surgery in June. Manoah also had Tommy John around that time and is hoping to be back by August.
Braves: Joe Jiménez
Jimenez had knee surgery in November with a timeline of eight to twelve months, so he might miss the entire season. Spencer Strider and Ronald Acuña Jr. are also possibilities, though those will be more borderline. Strider had internal brace surgery in April, so returning in May is somewhat possible. Acuña is recovering from a torn ACL last year and it’s possible he’ll miss the first month or so of the season. Given how important both of those players are, Atlanta probably won’t put them on the 60-day IL unless it’s 100% certain that they can’t come back in the first 60 days of the season.
Brewers: Robert Gasser
Gasser had Tommy John surgery in June and will be looking at a late 2025 return even in a best-case scenario.
Diamondbacks: Kyle Nelson
Nelson’s timeline is unclear, but he underwent surgery for thoracic outlet syndrome in May and missed the remainder of the 2024 season.
Dodgers: Gavin Stone, Brusdar Graterol, River Ryan, Kyle Hurt, Emmet Sheehan
Stone underwent shoulder surgery in October that will cause him to miss the entire year. Graterol also underwent shoulder surgery and isn’t expected back until the second half of 2025. Each of Ryan, Hurt and Sheehan required Tommy John surgery in 2024: Ryan in August, Hurt in July and Sheehan in May.
Guardians: Sam Hentges, David Fry, Shane Bieber, Trevor Stephan
Hentges required shoulder surgery in September, with an expected recovery timeline of 12 to 14 months. Fry underwent UCL surgery in November with a more fluid timeline. He won’t be able to throw at all in 2025 but could be cleared for designated hitter action six to eight months from that surgery. Bieber is perhaps a borderline case, as he underwent Tommy John surgery in April. Given his importance, the Guards may not transfer him to the 60-day IL until it’s assured that he won’t be back in the first 60 days of the season. Stephan underwent Tommy John surgery in March and perhaps has a chance to avoid the 60-day IL, depending on his progression.
Mariners: Matt Brash, Jackson Kowar
Brash underwent Tommy John surgery in May. Given the typical 14-month recovery timeline from that procedure, he would be looking at a midsummer return. However, it was reported in November that he’s ahead of schedule and could be back by the end of April. That’s an optimistic timeline but the Mariners will probably hold off moving him to the 60-day IL until the door is closed to an early return. Kowar underwent Tommy John in March, so an early return in 2025 is possible for him, depending on how his recovery is going.
Marlins: Braxton Garrett, Eury Pérez
Garrett just underwent UCL surgery last month and is going to miss the entire 2025 season. Pérez underwent Tommy John surgery in April of last year and will miss at least part of the beginning of the 2025 campaign.
Mets: Christian Scott
Scott required a Tommy John surgery and internal brace hybrid procedure in September and will likely miss the entire 2025 season.
Nationals: Josiah Gray, Mason Thompson
Gray required a Tommy John surgery and internal brace hybrid procedure in July, meaning he’ll miss most or perhaps all of the 2025 season. Thompson required Tommy John surgery in March, so he has a better chance to make an early-season return if his recovery is going well.
Orioles: Kyle Bradish, Tyler Wells
Bradish and Wells each required UCL surgery in June, so they’re both slated to miss the first half of the upcoming campaign.
Padres: Joe Musgrove
Musgrove had Tommy John surgery in October and will therefore miss the entire 2025 season. However, the Padres only have 36 guys on their 40-man roster at the moment, so they’ll need to fill those spots before moving Musgrove to the 60-day IL.
Pirates: Dauri Moreta
Moreta required UCL surgery in March, so an early-season return is possible if his rehab is going well, though he could end up on the 60-day if the club goes easy with his ramp-up or he suffers any kind of setback.
Rangers: Josh Sborz
Sborz underwent shoulder surgery in November and is expected to miss the first two to three months of the upcoming season.
Rays: Nate Lavender, Ha-Seong Kim
The Rays took Lavender from the Mets in the Rule 5 draft, even though he had Tommy John in May and will miss the start of the season. Kim’s status is more up in the air after he had shoulder surgery in October. Various reports have suggested he could return anywhere from April to July. The Rays made a sizable investment in Kim, their largest ever for a position player, so they probably won’t shelve him until they get more clarity on his status.
Red Sox: Patrick Sandoval, Garrett Whitlock, Chris Murphy
Sandoval had internal brace surgery in June of last year and should miss the first half of the season. Whitlock had the same surgery in May, so he could have a bit of a better chance to return in the first 60 days of the season. Murphy underwent a fully Tommy John surgery in April and will certainly miss the beginning of the upcoming season. Another possibility is Lucas Giolito, who had internal brace surgery in March, though he expects to be ready by Opening Day.
Reds: Julian Aguiar, Brandon Williamson
Aguiar underwent Tommy John surgery in October and Williamson in September, so both are likely slated to miss the entire 2025 season.
Tigers: Sawyer Gipson-Long
Gipson-Long underwent internal brace surgery in April. On top of that, he underwent left hip labral repair surgery in July, with the club hoping to address both issues at the same time. It seems likely that he’ll miss some of the early 2025 schedule, but his IL placement will depend on how he’s been progressing.
White Sox: Jesse Scholtens
Scholtens underwent Tommy John surgery in early March. Whether he goes on the 60-day IL or not will depend on how he’s progressed since then and when the White Sox expect him back.
Yankees: Jonathan Loáisiga
Loáisiga underwent internal brace surgery in April, so he could potentially be back on the mound early in the 2025 season. It was reported in December that the Yankees are expecting him to be in the bullpen by late April or early May, so he’ll only end up on the 60-day IL if he suffers a bit of a setback.
Mariners’ Jackson Kowar To Undergo Tommy John Surgery
The Mariners announced that right-hander Jackson Kowar has been placed on the 60-day injured list due to a tear in his right UCL. General manager Justin Hollander told reporters (including Ryan Divish of the Seattle Times) that Kowar will undergo Tommy John surgery next week, so the righty will now be out of action until around the midpoint of the 2025 season. The 60-day IL placement for Kowar creates a 40-man roster spot for Ryne Stanek, whose signing is now official.
It’s a brutal setback for Kowar, who went into 2024 looking for a fresh start. The Royals selected Kowar 33rd overall in the 2018 draft, and viewed the righty as one of several young arms that would help spur the organization’s next contention window. Unfortunately, Kowar (and basically all of Kansas City’s pitchers to date) has yet to show much in the big leagues, with only a 9.12 ERA to show for 74 innings over the last three seasons.
Kowar made eight starts in his 2021 debut season but has since worked only as a reliever in the majors. The move to the bullpen upped his fastball velocity but not much else, as batters have continued to tee off on Kowar’s offerings. Shaky control has also been detrimental to Kowar’s cause, with a 13.7% walk rate and a modest 20.1% strikeout rate.
The Royals opted to move on from Kowar in November when he was traded to the Braves for Kyle Wright, and Kowar’s stay in Atlanta lasted just a couple of weeks, as he was flipped to the Mariners as part of the five-player trade that brought Jarred Kelenic to Atlanta. From Seattle’s perspective, the trade moved a good deal of salary off the books at the cost of Kelenic, and the M’s got to pick up a couple of younger arms in Kowar and Cole Phillips, a second-round pick for the 2022 draft. Unfortunately, Phillips was already recovering from a TJ surgery and recently had to undergo a second procedure, while Kowar has now also been sidelined with the same surgery.
News surfaced earlier this week about a possible arm injury for Kowar, adding to a list of reliever injuries Seattle has already had to address this spring. Gregory Santos has been dealing with soreness is his teres major area but is back throwing bullpen sessions, while Hollander also said that Matt Brash is upping his games of catch to throws of 90 feet. Brash was recently given the green light to start throwing again after a bout of elbow inflammation, as it appeared as though he dodged what initially appeared to be a much more serious injury. Given all these health concerns, it isn’t surprising the Mariners felt the need to spend $4MM on Stanek to reinforce the relief corps.
