Poll: Who Will Be The Braves’ Fifth Starter?
The Atlanta rotation has had a rough go of it this spring. Spencer Schwellenbach and Hurston Waldrep both hit the injured list before Spring Training games even began, and now they’ve been followed by the loss of lefty Joey Wentz to a season-ending ACL tear. The timelines for Waldrep and Schwellenbach aren’t yet clear, but they figure to miss significant time following surgeries to remove loose bodies from their elbows. (Schwellenbach is already on the 60-day IL.) That leaves the Braves with a lot of uncertainty in the rotation. Grant Holmes and Reynaldo Lopez are coming off injury-marred 2025 seasons, but they’ll be relied on for mid-rotation innings behind Chris Sale and Spencer Strider.
There’s still one rotation spot open. Wentz was in position to make a play for that spot and had a decent spring showing: two runs, three hits, four walks, one hit batter, six punchouts in 5 2/3 innings (3.18 ERA). His injury opens the competition up to a larger group.
The on-paper favorite is likely to be right-hander Bryce Elder, who made 28 starts for the Braves last year. Elder is still just 27 years old and was an All-Star back in 2023 thanks to a big first half, but in his past 52 starts he’s posted a 5.63 ERA with a below-average 18.4% strikeout rate against an 8.3% walk rate. Metrics like SIERA (4.56) and FIP (4.76) have been a bit better kinder, but Elder is approaching 300 innings with an ERA north of 5.50 over the past two and a half calendar years.
Elder’s status as the presumptive favorite is more about incumbency, being on the 40-man roster and being out of minor league options. He hasn’t made a strong case this spring, turning in a lackluster 6.48 ERA in three starts. That leaves the door wide open for someone else to grab the job.
Left-hander José Suarez is also out of minor league options and on the 40-man roster. He has an uneven big league track record but pitched well between 61 2/3 minor league innings and 19 1/3 major league frames for Atlanta last winter. He’s allowed four runs in 6 2/3 spring innings. Suarez gave the Angels 207 1/3 innings of 3.86 ERA ball in 2021-22 before being tagged for a 6.91 ERA in 86 innings across a pair of injury-marred seasons in 2023-24.
The most prominent non-roster veteran in camp is southpaw Martín Pérez. The lefty has allowed only one run in five spring innings and is coming off a season where he posted decent numbers (3.54 ERA, 4.24 FIP) in 56 innings for the White Sox. Flexor and shoulder injuries shortened his 2025 season, and the days of Pérez’s blip of All-Star-caliber work with the Rangers (2.89 ERA, 3.9 fWAR in 2022) are likely behind him. Still, he has the potential to be an effective back-end starter.
Those aren’t the only options for the role. Veteran Carlos Carrasco is in camp, but after posting a 9.88 ERA in three starts for Atlanta last season and allowing nine runs on 11 hits in 6 1/3 spring innings this year, he seems unlikely to be the top choice. Didier Fuentes made his MLB debut last year and has tossed four scoreless innings this spring, but he won’t celebrate his 21st birthday until June and might be better served with more time in the minors. Top pitching prospect JR Ritchie enjoyed a strong season at Triple-A last year and has looked good so far this spring (3.38 ERA in eight innings). He’s not yet on the 40-man roster.
Another possibility that can’t be entirely ruled out is an external addition. Lucas Giolito remains available and seems like an obvious fit — despite an apparent lack of interest on Atlanta’s part thus far. Other veterans like Tyler Anderson and Patrick Corbin remain unsigned, too. Any of those pitchers could be added to the mix with the intent of them eventually taking over the fifth starter job, but the team would likely need to trade for a player that’s already been pitching for another club in order to add someone who will immediately be ready to join the rotation at the start of the season. A free agent like Giolito would surely need to get work in at extended Spring Training at this point.
How do MLBTR readers think the Braves will round out their rotation? Will they give the job to Elder and hope for better results than last year? Will they go with a young prospect like Fuentes or Ritchie, or perhaps a veteran like Pérez or Carrasco? Perhaps they’ll eschew all those options for an external addition? Vote now in the poll below:
Who will be the Braves' fifth starter this year?
The Opener: World Baseball Classic, Teel, Carroll
Here are three things we’ll be keeping an eye on around the baseball world throughout the day today:
1. World Baseball Classic continues:
After Team Italy’s shocking 8-6 victory over Team USA last night, the World Baseball Classic enters its final day of Pool Play with plenty at stake. At 3pm local time in San Juan, Canada and Cuba will face off to decide who will join Puerto Rico in the quarterfinals. That game will be followed up at 6pm local time in Houston, when Italy and Mexico will face off to determine not only their own fates, but also the fate of Team USA. The United States can be eliminated if Mexico beats Italy while scoring four runs or fewer, as all three teams would finish with 3-1 records and move on to a runs-based tiebreaker. The final game of the evening will occur at 8pm local time in Miami, where the Dominican Republic and Venezuela will face off for seeding purposes after both clubs already clinched their quarterfinal appearance.
Outside of the excitement of the games themselves, this year’s WBC has already brought considerable intrigue and drama off the field. Team USA manager Mark DeRosa conducted an interview pregame where he seemingly did not realize that his club had not already clinched a spot in the quarterfinals, and Chad Jennings of The Athletic notes that MLB.com appears to have taken down the footage of DeRosa’s mistaken comments after Team USA’s loss. Meanwhile, USA Today’s Bob Nightengale was among those to discuss possible discontent in the Mariners’ clubhouse after star catcher Cal Raleigh declined to shake hands with Mariners teammate and WBC opponent Randy Arozarena during the game between the U.S. and Mexico yesterday.
2. Teel exits due to hamstring issue:
In other WBC news, a damper was put on Italy’s victory when catcher Kyle Teel was pulled from the game due to tightness in his right hamstring. As noted by Anthony Castrovince of MLB.com, Teel figures to be replaced on Italy’s roster by bullpen catcher Andres Annunziata. Annunziata is a 20-year-old who plays in Italy’s Serie A league. Perhaps more pertinent than Teel’s WBC status is whether or not he’ll be hampered headed into the regular season for the White Sox. He’ll surely get imaging done on his ailing hamstring to determine the severity of the issue, and the White Sox will be able to formulate a plan for Teel from there. Fortunately for them, Edgar Quero and Korey Lee are available as a capable catching tandem even if Teel misses the start of the season.
3. Carroll returning to the lineup:
Corbin Carroll has missed the bulk of Spring Training so far due to a hamate fracture that ultimately required surgery, but Alex Weiner of the Arizona Republic relayed yesterday that the Diamondbacks’ star outfielder will be back in the lineup today as a DH. With a little over two weeks left to go before Opening Day, Carroll should have just enough time to ramp up before the season begins and avoid starting the year on the injured list. His return to the field begins at 1:10pm local time in Arizona, when Ryne Nelson will be taking the mound opposite Luis Morales and the Athletics.
Poll: Will The Astros Be Able To Add Another Outfielder Before Opening Day?
One of the biggest predicaments of the Astros’ offseason has been their as-of-yet unsuccessful efforts to reshape their outfield mix. After losing Kyle Tucker in a trade to the Cubs last winter, the team not only missed the playoffs for the first time in a decade but struggled to find production in the outfield. Their 88 wRC+ on the grass was the eighth-weakest in the majors, and while strong defense from Jake Meyers in center field helped to raise their ranking in terms of fWAR, the club’s outfield still ranked just 20th in baseball even by that measure.
Things have arguably gotten worse in the outfield for Houston this winter, depending on who you’d take between Jesus Sanchez and Joey Loperfido. As presently constructed, Meyers figures to handle center field with some combination of Loperfido, Cam Smith, Zach Cole, Brice Matthews, and Zach Dezenzo platooning in the corners. Smith is the only one with even 400 plate appearances at the big league level for his career of that group, and he’s a 23-year-old coming off a middling rookie season after getting just 32 games in the minors (and only five above High-A) before making his debut. It’s a very unproven group, and it’s been no secret that even after the calendar flipped to March with Opening Day just weeks away, the Astros are hoping to find a way to add some additional stability to their outfield.
For most of the offseason, the industry consensus was that they were most likely to accomplish that by dealing away Isaac Paredes. Paredes, at least on paper, was blocked all over the diamond after the team acquired Carlos Correa to play third base at last year’s trade deadline. With Correa at third, Christian Walker at first, and Yordan Alvarez at DH, there wasn’t much of anywhere for Paredes to play. Perhaps the team was still holding out hope that the right deal would come through at some point but a recent finger fracture suffered by Jeremy Pena perhaps changes that calculus. If Pena has to miss time, Correa could be thrust back into the role of everyday shortstop, which would leave the hot corner for Paredes to get regular at-bats to open the season.
That means a major trade for someone like Jarren Duran is extremely unlikely at this point. With that being said, though, there are certainly other ways the team could look to improve its outfield even as Opening Day creeps closer. Free agency (Jesse Winker, Jason Heyward) offers a couple of interesting if unexciting options who could likely be brought into camp on a minor league deal.
The best NRI candidates have been picked over by other clubs at this point, but if a player like Michael Conforto (who the Astros reportedly had interest in before he signed with the Cubs) or Mike Tauchman fails to make their current team out of camp, then it’s entirely possible they could opt out of their current deals and find a home in Houston.
It’s even possible that a deal involving a player on another team’s major league roster isn’t completely out of the question. MLBTR’s Anthony Franco explored a handful of little-discussed trade candidates who could make sense for the Astros last month. While there’s no guarantee any of those players are available, it’s fair to think a team like the Twins (who have all of Matt Wallner, Trevor Larnach, Alan Roden, and James Outman vying for just a few spots in their outfield mix) could be willing to part with one of those pieces. That would be especially intriguing for Minnesota if the Astros were open to listening on some of their pitching depth, given that the Twins will be without Pablo Lopez this year and David Festa is also slated to start the year on the injured list.
What do MLBTR readers think of the Astros’ outfield situation? Will they be able to find some external help before the season begins? Or will they enter the year with some combination of their internal players handling the corners? Have your say in the poll below:
Will the Astros add another outfielder before Opening Day?
Nationals Sign Zack Littell
The Nationals have formally added a second veteran starter in free agency, announcing the addition of righty Zack Littell on a one-year deal with a mutual option for the 2027 season. Littell, a client of CAA, will reportedly be guaranteed $7MM with another $2.5MM available to him via innings-based incentives. Left-hander Richard Lovelady was designated for assignment to open roster space, per the team.
Littell’s deal reportedly pays him a $3MM salary but also includes a $4MM buyout on that mutual option. Since mutual options are never exercised, that amounts to little more than an accounting measure; the Nats are kicking $4MM of his $7MM commitment to the 2027 books rather than the 2026 books. The contract is also said to contain $100K bonuses for every tenth inning pitched from 100 through 140. Littell can earn $250K for reaching each of 150 and 160 innings, and the deal has $500K bonuses upon reaching 170, 180 and 190 innings.
Heading into the offseason, we ranked Littell 35th among the offseason’s top 50 free agents, predicting a two-year deal. He’ll have to settle for just a one-year pact, and the righty could be on the move again relatively soon if the rebuilding Nationals move him at the trade deadline.
The 30-year-old Littell is a veteran of eight big league seasons but spent most of that time in a bullpen role. In the first five seasons of his MLB career, Littell posted a 4.08 ERA (104 ERA+) with lackluster peripherals in 169 2/3 innings of work. After the 2022 campaign, Littell rode the DFA and waiver carousel throughout the 2022-23 offseason. He eventually wound up with the Red Sox to start the season, but he made just two appearances in the majors before being once again designated for assignment. That led him to the Rays, with whom he managed to transform himself from a fringe member of the 40-man roster into a solid rotation arm.
Upon arriving in Tampa, Littell moved into a swing role for the remainder of the 2023 campaign. He posted a 3.93 ERA with a nearly matching 3.99 FIP in 87 innings split between 14 starts and 12 relief appearances. Littell’s 19.8% strikeout rate in those outings was hardly exciting, but he made up for it with pinpoint command that allowed him to post a 2.5% walk rate and an 8.2% barrel rate.
That control and command style was enough to earn him a full-time rotation job headed into the Rays’ 2024 season, and he rewarded the team with a career year. In 29 starts for the Rays in 2024, Littell posted a 21.5% strikeout rate against a 4.7% walk rate while pitching to a 3.63 ERA (110 ERA+) with a 3.81 FIP. His 156 2/3 innings of work made him just one of just 71 pitchers to throw more than 150 innings that year, and only 15 of those pitchers surrendered fewer runs than Littell.
Littell remained generally effective in terms of run prevention last year, logging a 3.81 ERA (111 ERA+) in a career-high 186 2/3 innings across 32 starts for the Rays and Reds. The bottom-line results were similar, but Littell’s rate stats took worrying steps in the wrong direction. His strikeout rate plummeted to just 17.1%, while his barrel rate jumped to 9.8% as he allowed the second-most homers in all of baseball last season. Perhaps some of that can be explained by Littell pitching his home games at the hitter-friendly Steinbrenner Field and Great American Ballpark, but a 4.40 SIERA suggested that Littell was more of a back-end starter than his results may have indicated.
The result was a soft free agent market for Littell this offseason. A reunion with the Rays once seemed to be on the table, but Tampa Bay instead brought in Steven Matz and Nick Martinez. KSTP’s Darren Wolfson reports that the Twins at least checked in late in the offseason, but weren’t inclined to match the Nationals’ offer.
The Nationals were the ones to ultimately bring Littell into the fold, with some past connections possibly helped complete the deal. New president of baseball operations Paul Toboni formerly worked in the Red Sox front office, new manager Blake Butera spent years managing in Tampa’s farm system, and new pitching coach Simon Matthews was the Reds’ assistant pitching coach in 2025, so all three have direct familiarity with Littell’s work.
D.C. is unlikely to compete for a playoff spot this year as they reboot their rebuilding efforts under Toboni. As such, the team has pursued just short-term and relatively inexpensive veteran signings like Littell and Miles Mikolas, and made another move for the future in trading MacKenzie Gore to the Rangers. The Gore trade diminished an already questionable Washington rotation, so Littell will reinforce a starting five that seems set to include Mikolas and another new signing in Foster Griffin. The last two spots in the rotation figure to go to some combination of Cade Cavalli, Brad Lord, Josiah Gray, Jake Irvin, and Mitchell Parker.
ESPN.com’s Kiley McDaniel and Jeff Passan were the first to report the agreement between the two sides. The Baltimore Banner’s Andy Kostka (multiple links) had the details about the one-year term and mutual option. The Banner’s Andrew Golden first reported the financial guarantee. Jon Heyman of The New York Post and Spencer Nusbaum of The Athletic added specifics about the breakdown and incentives.

The Opener: World Baseball Classic, Extensions, MLBTR Chat
Here are three things for MLBTR readers to keep an eye on throughout the day:
1. World Baseball Classic continues:
Pool play in the World Baseball Classic continues today, although we already know which two teams will advance from Pool C (Japan, Korea) and Pool D (Venezuela, Dominican Republic). Puerto Rico in Pool A and USA in Pool B both have 3-0 records, with Puerto Rico having already clinched a spot in the quarterfinals. Team USA will need to beat Team Italy in this evening’s game (scheduled for 8pm local time in Houston) in order to clinch their spot; a loss to Italy tonight in conjunction with Italy losing to Mexico tomorrow would then result in a tiebreaker between the three clubs, who would have identical 3-1 records. As for Pool A, Cuba (2-1) is currently in the best position to make the quarterfinals, but Canada (1-1) could make things interesting with a win over Puerto Rico at 7pm ET.
2. More extensions on the way?
Yesterday, the Phillies stunned the baseball world with an out-of-the-blue extension for left-hander Jesus Luzardo. Luzardo landed a five-year, $135MM deal just months before he would have reached free agency. The 28-year-old signed on the heels of a season where he posted a 3.92 ERA in 32 starts with outstanding peripherals (2.90 FIP, 28.5% strikeout rate). Luzardo’s deal serves as a reminder that a lack of rumors surrounding a given player doesn’t necessarily signal a lack of negotiation going on behind the scenes. Luzardo joins Braves southpaw Chris Sale, Dodgers third baseman Max Muncy and A’s shortstop Jacob Wilson among the list of notable players to sign extensions in the past five to six weeks. Cardinals manager Oli Marmol, Brewers skipper Pat Murphy, and Padres president of baseball operations AJ Preller have also signed new contracts this spring.
As for Luzardo, his extension is expected to be formally announced by the team at a press conference today, per the New York Post’s Jon Heyman. That could lead to some comments of note from Phillies president Dave Dombrowski, so fans will want to keep an eye out for that.
3. MLBTR Chat today:
The World Baseball Classic is underway, and MLB clubs are entering the final weeks of Spring Training. Free agency is nearing its conclusion (the as-of-yet unsigned Lucas Giolito notwithstanding), and teams around baseball are gearing up for the 2026 campaign. If you’re wondering where your club stands, how their offseason went, or if there might be any other moves for your club to make before the season begins, you can get MLBTR’s Steve Adams thoughts in a chat that’s scheduled for 1pm CT. You can click here to ask a question in advance, follow along once it goes live, and read the transcript after it’s complete.
The Opener: World Baseball Classic, Littell, Giolito
Here are three things we’ll be keeping an eye on around the baseball world throughout the day today:
1. WBC pool play continues:
Pool play in the World Baseball Classic remains underway, with Samurai Japan (3-0) and Korea (2-2) both having advanced out of the pool stage of the tournament. Those two clubs will be the quarterfinalists from Pool C. In Pool A, the favorites to advance are Puerto Rico and Cuba, both of which have 2-0 records. The same can be said for the Dominican Republic and Venezuela in Pool D given their own 2-0 records. The most interesting pool at the moment is Pool B, where each of the United States, Italy, and Mexico have perfect 2-0 records. The winner of tonight’s game between Team USA and Team Mexico will be an overwhelming favorite to secure a spot in the quarterfinals. The U.S. will send reigning NL Cy Young Award winner Paul Skenes to the mound against former Orioles right-hander Manny Barreda.
2. Littell contract to be finalized:
The Nationals and right-hander Zack Littell have reportedly agreed to one-year contract that includes a mutual option for 2027. That deal was pending a physical, however, and the exact dollar amount of the deal has not yet been reported. Financial details figure to become available at some point in the near future, and the deal should be finalized quickly in the interest of getting the righty into camp with the Nats; there are just over two weeks until the regular season begins. The Nationals will need to make a 40-man roster move to accommodate the addition of Littell, and the club has no obvious 60-day IL candidates after already transferring Trevor Williams and DJ Herz earlier this spring.
3. Giolito stands alone:
Now that Littell has a deal, right-hander Lucas Giolito stands alone as the final member of MLBTR’s top 50 free agents list who has yet to land a deal somewhere. MLBTR’s Steve Adams took a look at a handful of teams that remained plausible candidates to add a starter like Giolito to the mix back in February, and many of those teams still make some sense for his services. Clubs like the Braves and Phillies that look like plausible fits on paper have indicated a lack of interest in the right-hander to this point.
Of course, the nature of pitcher injuries (particularly in Spring Training) is such that any given pitch thrown by a player expected to be in the rotation mix for their team could lead to an injury that creates an opening for Giolito. That’s been all too apparent in Atlanta, where injuries to Spencer Schwellenbach and Hurston Waldrep at the start of camp have more recently been compounded by an injury to Joey Wentz. Wentz was carted off the field with an apparent right knee injury sustained while covering the bag on a grounder to first. Initial reports were that Wentz seemed to have avoided a major injury, but he was still being sent for imaging. If he’s forced to miss some time, perhaps losing a third rotation option would push the Braves to consider some external additions.
Mariners Add Jacob Nottingham To Minor League Coaching Staff
March 9: Nottingham was brought in as a player on a minor league deal but will actually be converting to coaching, according to a report from Ryan Divish of The Seattle Times. It’s unclear what Nottingham’s exact role in the Mariners organization will be. The news presumably ends Nottingham’s playing career, and we at MLB Trade Rumors wish him all the best in his upcoming move to coaching.
March 8: The Mariners have re-signed catcher Jacob Nottingham to a minor league deal, as noted in the transactions tracker on Nottingham’s MLB.com profile page. It’s unclear if the deal includes an invite to big league camp for the 30-year-old.
Nottingham is a veteran of four MLB seasons but hasn’t appeared in the majors since the 2021 season. A one-time top-100 prospect who was initially drafted by the Astros, he was involved in the 2015 Scott Kazmir swap between the Astros and A’s before being flipped to the Brewers in the Khris Davis deal ahead of the 2016 season. Nottingham lost his prospect shine during his time in Milwaukee and served mostly as an up-and-down catcher for the Brewers from the time of his MLB debut in 2018 until 2021, when he was claimed off waivers by the Mariners. He returned to the Brewers via trade shortly thereafter but was eventually DFA’d by Milwaukee and plucked off waivers by Seattle for a second time later in the year.
Then 26 years old, Nottingham ended the 2021 season with a career .184/.277/.421 slash line across 130 plate appearances in 54 MLB games, which remains his career slash line in the big leagues to this day. Since being outrighted off the Mariners’ roster in 2021, he’s bounced between the Mariners’, Giants’ and Nationals’ minor league systems and also enjoyed a 44-game stint in the independent Mexican League back in 2024. In 293 career minor league games, Nottingham owns a .235/.321/.415 slash line line that’s generally solid by the standards of a catcher. Those numbers are somewhat inflated by years spent in the Pacific Coast League, however, and Nottingham’s 2025 campaign left much to be desired. He appeared in just 17 games in Tacoma for the Mariners organization last year, and in those limited opportunities he struggled to the tune of a .193/.277/.298 slash line.
Given Nottingham’s limited playing time last year and struggles when he did take the field, it’s hard to imagine him being a significant part of the backup catcher conversation for Seattle. Cal Raleigh is, of course, the undisputed top catcher in not only the organization but all of baseball. The Mariners are planning on having Andrew Knizner back Raleigh up this year, although Jhonny Pereda is also on the 40-man roster while Mitch Garver, Brian O’Keefe, and Jakson Reetz are all in camp as non-roster invitees. Some of those depth options figure to have opt-outs in their contracts and could look for greener pastures elsewhere in the likely event they don’t make the MLB club. That’s where Nottingham could come into the picture as a depth piece who is familiar with the organization and can serve as a veteran mentor for pitchers at Triple-A.
Rangers Claim Dairon Blanco
The Rangers have claimed outfielder Dairon Blanco off waivers from the Royals, according to Francys Romero of Beisbol FR. Blanco was designated for assignment by the Royals last week to make room for Starling Marte on the club’s 40-man. The Rangers transferred southpaw Jordan Montgomery to the 60-day injured list to make room for Blanco on their own 40-man.
Blanco, 33 next month, played in the Cuban National Series through his age-22 season but didn’t make it to stateside ball until he was 25 years old back in 2018. Then a member of the Athletics, he was traded to the Royals the following year and eventually made his big league debut during the 2022 season with a five game cup of coffee. The following year he got a much larger role with Kansas City, however, and over the next two seasons he slashed a solid .258/.316/.422 in 270 plate appearances across 157 games. That’s slightly above league average production at the plate, though the vast majority of his production comes against left-handed pitching. Blanco sports a 137 wRC+ for his career against southpaws, compared to a 70 wRC+ against right-handers. It’s also worth noting that he gets a lot of value from his work on the base paths, where he went 55-for-67 (82.1%) in stolen base attempts in 2023 and ’24.
That makes Blanco a useful bench or depth option to be sure, but he ultimately found himself squeezed off the Royals’ roster after the team brought in Marte and Isaac Collins during the offseason to shore up an outfield mix that had rated out as among the worst in the majors in recent years. The Royals already had a crowded bench mix, and Blanco has yet to prove he’s capable of handling more than part-time duties at the big league level. That’s unlikely to be as much of a problem with the Rangers, who are relatively thin on outfield depth (especially when looking for players who can play center field capably) and have plenty of lefties in the lineup like Evan Carter, Joc Pederson, and Josh Smith who could benefit from being spelled against fellow southpaws.
Of course, that isn’t to say Blanco is guaranteed a spot on the team’s bench entering the season. He’ll have stiff competition from veteran Andrew McCutchen for a spot as a right-handed bat, while Sam Haggerty, Michael Helman, and Ezequiel Duran all offer more versatility than Blanco. With that being said, Blanco does have options remaining and could simply start the season in the minor leagues before waiting to get an opportunity in the majors at some point this year. At the very least, Blanco’s wheels should give him a strong argument to join the team when rosters expand in September and perhaps into the postseason if Texas manages to make it that far.
Robert Stock Recommended For Thoracic Outlet Syndrome Surgery
Mets right-hander Robert Stock has been recommended for surgery to correct thoracic outlet syndrome, Stock told reporters (including Jon Heyman of the New York Post) this morning. Heyman adds that Stock indicated he’s suffering from the arterial TOS, and that he could potentially pitch before the end of the year. Stock was in camp with the Mets on a non-roster invite but is now facing a lengthy absence.
Stock, 36, has appeared in parts of five MLB seasons to this point in his career. A second-round pick by the Cardinals back in 2009, he made a strong impression with the Padres in 2018, his first season as a big leaguer. He posted a 2.50 ERA in 39 2/3 innings of work that year, but unfortunately he’s struggled at the big league level since then. In just 35 2/3 major league frames since, Stock sports a 7.57 ERA with nearly as many walks (31) as strikeouts (39). Stock did not appear in the majors from 2022-2024, instead bouncing between the KBO, the minor leagues, and independent leagues in both the United States and Mexico. In 2025, he returned to affiliated ball with the Red Sox. While he made just two abbreviated appearance in the majors, he pitched decently at Triple-A Worcester with a 3.92 ERA in 85 innings as a swing man.
That led Stock to sign a minor league deal with the Mets headed into 2026, and he figured to be a versatile depth option for the club’s pitching staff headed into the year. He’s pitched well so far this spring, including a strong three-inning appearance against the Marlins while preparing to pitch for Team Israel in the World Baseball Classic. Unfortunately, that outing ended with him reporting discomfort in his shoulder. That led to the MRI which ultimately revealed he was suffering from TOS. The specific kind of TOS Stock is suffering from is arterial TOS, the rarest form of the disorder. While baseball fans have become increasingly familiar with TOS in recent years, they’re likely to be more familiar with neurogenic TOS (the form of the disorder that players such as Stephen Strasburg and Chris Archer suffered from) and venous TOS, which Phillies star Zack Wheeler is currently working his way back from after being sidelined late last year by the disorder.
Arterial TOS is far less common than the other two versions, and its impacts on baseball players are far less widely understood; a 2024 study published in the American journal of sports medicine (link via NIH.gov) that looked at all 52 players who underwent surgical treatment for TOS between 2010 and 2017 notes that just one of those 52 players was suffering from arterial TOS. An article from Anthony Castrovince of MLB.com last month notes that arterial TOS can cause a feeling of coldness in the hand or even finger gangrene. Castrovince’s article notes that a return to play timeline of between nine and ten months is typical for pitchers who undergo surgery to correct TOS, though that can depend on the severity and form of TOS the player is facing. Stock’s hopes for his timeline are significantly more optimistic than that, as even a September return would be a turnaround of just six months.
Whether Stock is able to make it back to the mound this year or not, the Mets are fairly well equipped to handle losing him as a depth piece. Justin Hagenman, Christian Scott, and Jonathan Pintaro are all depth options for the rotation already on the 40-man roster, and that’s before considering top prospect Jonah Tong. As for the bullpen, the Mets have a deep group of non-roster invitees headlined by Craig Kimbrel, Adbert Alzolay, and Kevin Herget among others.
Poll: Will Munetaka Murakami Or Tatsuya Imai Have The Better Rookie Year?
All around the baseball world, the offseason started with a great deal of hype for the two top talents coming over from Japan to play in MLB: slugger Munetaka Murakami and starter Tatsuya Imai. Both players seemed likely to follow in the footsteps of other recent stars to make the jump from NPB to the majors, including Yoshinobu Yamamoto and Seiya Suzuki, and be among the most coveted free agents on the market. Things did not pan out that way, however, as both players found surprisingly soft markets and wound up taking short-term deals with the hope of returning to the open market after establishing themselves as quality big leaguers.
As they prepare for their respective rookie seasons, Murakami as a member of the White Sox and Imai with the Astros, who is better positioned to do just that? When looking at the contracts the pair got, it’s easy to argue that Imai’s more lucrative deal indicates a greater level of confidence in his ability to succeed. He landed a three-year, $54MM contract with Houston back in January that provides him the opportunity to opt out after either the 2026 or ’27 season. That’s an extra year and $20MM relative to Murakami’s deal in Chicago, not to mention that Murakami doesn’t have an opt-out clause in his deal.
It’s easy to see why teams would’ve had a bit more confidence in Imai than Murakami. Murakami comes with multiple unique questions, including whether his defense will hold up in the majors at either first or third base and whether there’s room for improvement on his extremely low contact rates from his time overseas. Imai doesn’t really come with comparable concerns; his mid-90s velocity and four-pitch mix are strong bets to play in the majors in terms of floor, leaving the Astros less likely to come up completely empty on their investment than the White Sox.
What Murakami lacks in terms of floor, however, it can be argued that he makes up for with exceptional upside. Murakami’s contact rates might be among the lowest in the majors if translated over, but players like Shohei Ohtani, Aaron Judge, Kyle Schwarber, and Nick Kurtz are among the most productive hitters in the entire sport despite high strikeout rates and a proclivity for racking up whiffs. It’s easy to see why Murakami’s sensational exit velocities could allow him to compare to those elite sluggers, particularly given that he only just celebrated his 26th birthday.
It’s fair to wonder if Imai has that sort of elite upside to offer. While his velocity is impressive, scouts have suggested that his fastball lacks the movement necessary to be a high-end pitch. That in conjunction with the control issues he’s flashed at various points in his MLB career might cap his ceiling at something closer to the middle of a big league rotation. Murakami, by contrast, could find himself battling with the likes of Judge and Cal Raleigh at the top of the home run leaderboards if he manages to make enough contact to be productive and continues to grow as a player.
If Murakami breaks out the way some both in Japan and the United States have believed he’s capable of doing, it’s hard to imagine Imai being able to hold a candle to that production no matter how close to his own ceiling he gets. With that said, it could be difficult for either to make much noise in Rookie of the Year conversations. The AL figures to feature a stacked class including players like Kevin McGonigle, Samuel Basallo, Dylan Beavers, Trey Yesavage, and Carter Jensen. Even if Murakami or Imai outproduces those players, their status as foreign professionals already in their mid-20s could still hurt them in Rookie of the Year voting, especially against younger players like McGonigle and Basallo.
