Diamondbacks Outright Luken Baker
The D-Backs sent first baseman Luken Baker outright to Triple-A Reno, according to the MLB.com transaction log. Arizona had designated him for assignment when they welcomed Lourdes Gurriel Jr. back from the injured list on Saturday. This is Baker’s second career outright, meaning he has the right to elect free agency.
Baker was on the major league roster for a little less than two weeks. He was called up on April 7 as a bench bat once the Snakes lost Carlos Santana to an adductor strain. The D-Backs only gave him one start over his 11 days on the active roster. Baker went 1-5 while striking out three times over three games overall.
That marked the fourth straight season with some MLB action for the former second-round draftee. It’s his first MLB work outside of St. Louis. The former Cardinals draftee had spent his career in that organization until he was claimed off waivers by the Dodgers last August. Baker didn’t appear in an MLB game with Los Angeles, who outrighted him off the 40-man roster within a week of claiming him. He joined Arizona on an offseason minor league deal.
The righty hitter owns a .206/.314/.333 batting line across 194 plate appearances at the big league level. Baker mashed a combined 65 home runs in Triple-A between 2023-24. His minor league production backed up last year, as he slashed a league average .223/.335/.441 through 95 games across the two systems.
Baker is out of minor league options, so the D-Backs needed to run him through waivers to take him off the MLB roster. It’d make sense for him to remain in the organization given their lack of established first basemen. Santana is joined by Pavin Smith and Tyler Locklear on the injured list. Utilityman Ildemaro Vargas and rookie infielder Jose Fernandez are splitting the first base work.
Edwin Uceta Diagnosed With Subscapularis Strain
Rays reliever Edwin Uceta has been diagnosed with a subscapularis strain in his throwing shoulder, manager Kevin Cash told reporters on Monday afternoon (link via Adam Berry of MLB.com). The righty will be shut down completely for another 2-3 weeks.
Uceta was already down with a shoulder impingement. This is a different injury that arose during his rehab assignment. Uceta had made four minor league appearances and would likely have been activated this week if not for the new injury.
There’s now a decent chance he’ll end up on the 60-day injured list once the team needs a 40-man roster spot. The Rays could backdate any IL transfer to Opening Day even though it’s a different injury. Uceta won’t resume throwing until the first half of May at this point, so it’s difficult to imagine he’ll be ready for MLB action by the beginning of June.
It’s a tough hit to the Tampa Bay bullpen. Uceta has been one of their better relievers over the past two seasons and was slated for a high-leverage role. He turned in a 1.51 ERA across 41 2/3 innings two years ago. Last season’s 3.79 mark wasn’t as impressive, but he struck out almost a third of opposing hitters while tying Garrett Cleavinger for the team lead with 21 holds.
Cleavinger has also been down for the past three weeks with calf tightness. He’s on a rehab assignment and should be back within the next couple days. Tampa Bay placed Mason Englert on the 15-day IL this afternoon. They’ll be without Manuel Rodríguez for the majority of the season and are without middle reliever Steven Wilson for a couple months.
It’s not a coincidence that the relief corps has been a weakness for the first couple weeks of the season. Kevin Kelly, Griffin Jax, Bryan Baker and Hunter Bigge have taken on most of the significant innings. Bigge has the best ERA but with ugly strikeout and walk marks. Jax has similarly bleak underlying numbers and has not gotten good results. Baker has been around average, while Kelly has pitched well outside of one six-run drubbing at the hands of the Twins.
The Rays entered played Monday with a 5.38 bullpen ERA that ranks 26th in MLB. They’re 25th in strikeout/walk rate differential with the league’s third-highest home run rate.
Astros Outright J.P. France
The Astros announced that right-hander J.P. France has been outrighted to Triple-A Sugar Land. That indicates he cleared waivers after being designated for assignment last week. France has the right to elect free agency but the club announcement didn’t say whether or not he would do so.
A player has the right to reject an outright assignment in favor of free agency if he has at least three years of service time or a previous career outright. Houston outrighted France in February, an assignment he had to accept since it was his first. A number of injuries led them to select him back to the roster earlier this month. Now that this is his second outright, he could look for opportunities elsewhere.
If he did head for the open market, he would likely be limited to minor league offers. Every club just passed on the chance to give him a 40-man spot, even though he is still optionable and could have been stashed in the minors. Perhaps he will simply stay with the only organization he has ever known, but he can roam if he wants to.
France’s best season was back in 2023, when he debuted and tossed 136 1/3 innings, allowing 3.83 earned runs per nine. There were some asterisks there, as his 17.4% strikeout rate was subpar and his 76.7% strand rate was high, which is why ERA estimators like his 4.66 FIP and 4.96 SIERA were a bit more bearish.
He hasn’t been able to pitch much in the majors since then. Shoulder problems nagged at him in 2024 and ultimately required surgery. He made seven big league appearances over those two seasons, with a 6.75 ERA. As mentioned, he cleared waivers coming into this season and was briefly back on the roster.
If he sticks around, the Astros may need him again in the near future. Their injured list features starters Hunter Brown, Cristian Javier, Tatsuya Imai, Cody Bolton, Ronel Blanco, Hayden Wesneski and Brandon Walter. Their big league rotation currently features Mike Burrows, Spencer Arrighetti, Ryan Weiss, Peter Lambert and Lance McCullers Jr., with Colton Gordon also on the roster and capable of eating some innings. Apart from Burrows and McCullers, those guys only just entered the mix recently due to the injuries, so they probably don’t have firm grips on their current roles.
Miguel Ullola and Jason Alexander are also on the 40-man roster. Brandon Bielak and Miguel Yajure have recently been added via minor league deals. If France accepts his outright assignment, he would join Bielak and Yajure in the non-roster depth category.

6 Potential Breakout Arms To Watch In 2026
The early stages of any major league season are rife with unexpected performances -- be they unexpectedly good or unexpectedly bad -- that leave many fans and onlookers wondering whether an April change in production is the beginning of a trend or simply some small-sample noise that'll even out over a larger slate of plate appearances or innings pitched. Sifting through what's real and what's likelier to be smoke and mirrors is both one of the most exciting and also most frustrating elements of the season's first couple months.
This, as with most everything in baseball, is an inexact science. Teams spend millions to build out data and analytics departments that can develop predictive models in an effort to more accurately quantify these things. Sites like FanGraphs, Baseball Prospectus, PitcherList, Baseball America and countless others offer heaps of publicly available data that allow those of us on the outside looking in to throw our own hats into the ring as we attempt to decipher whose ostensible breakouts are going to hold up ... and who'll come back down to Earth.
MLBTR's Darragh McDonald took a look last week at Jose Soriano's in-progress breakout in Anaheim -- a huge development for the Halos that could have a broad range of implications. Readers are encouraged to check that out in full, but here are six more arms (plus a couple "honorable mentions," of sorts) whose 2026 strides have piqued my interest. Obviously, this isn't a comprehensive list of every possible breakout arm in the sport, but the arrows here are pointing up. (Players are listed alphabetically, not ranked.)

Mariners Place Brendan Donovan On IL, Select Will Wilson
8:33pm: Emerson is battling wrist soreness in Triple-A, manager Dan Wilson told reporters (including Adam Jude of The Seattle Times). There’s no indication the team is concerned about the issue, but that played a role in their decision not to promote him yet. The M’s also don’t anticipate Donovan missing much time, so it made more sense to tab Will Wilson if they’re only looking for a short-term utility stopgap.
4:25pm: The Mariners announced that they have selected the contract of infielder Will Wilson. He will take the active roster spot of infielder/outfielder Brendan Donovan, who has been placed on the 10-day injured list with a left groin muscle strain, retroactive to April 18th. To open a 40-man spot, infielder/outfielder Miles Mastrobuoni has been transferred to the 60-day injured list.
Donovan was removed from Friday’s game due to a left hip issue. He didn’t play on Saturday or Sunday. He had previously dealt with a right groin issue earlier in the season. Per Daniel Kramer of MLB.com, Donovan believed it was possible that his earlier groin discomfort may have been related to the sports hernia surgery he underwent back in October.
That surgery didn’t prevent Donovan from being one of the hottest trade chips of the winter. Several clubs were interested and Seattle eventually landed him in a three-team trade that saw them send out infielder Ben Williamson, prospects Jurrangelo Cijntje and Tai Peete, as well as a competitive balance round B pick.
Donovan was a particularly good fit for the Mariners roster because of his defensive versatility. Coming into this year, it wasn’t clear what would happen at second or third base, with Cole Young and Colt Emerson possible solutions at those positions. Young has taken over at second and has been playing well so far. Emerson, despite signing a long contract extension, has been in the minors. That has left Donovan to cover third and he has a strong .304/.437/.518 line when he has been able to take the field.
It’s not clear how long the Mariners expect Donovan to be out but they’ll have to proceed without him for more than a week, at least. They could have called up Emerson but have decided not to, at least for now. He is playing well for Tacoma but is still only 20 years old and only has 24 games at Triple-A under his belt, so it seems they have decided to keep him there.
Leo Rivas has picked up the past two starts at third base with Donovan out. He has a rough .143/.295/.184 line on the year but a better .217/.348/.278 slash for his career. A switch-hitter, he has been far better against righties, with a .221/.372/.305 line in that split compared to a .210/.304/.235 line versus lefties.
Wilson, 27, is a right-handed bat but hasn’t had strong splits throughout his career. In much of his minor league career, he’s actually been better against righties, so he’s not an ideal platoon bat for Rivas. He might just be more of a general depth infielder off the bench. He has plenty of minor league experience at the three infield positions to the left of first base, and some limited outfield experience as well.
His major league track record is still fairly small. He got into 31 games with the Guardians last year and slashed .192/.267/.244. His upper level minor league work hasn’t been much better, though his Triple-A line of .250/.333/.430 since the start of 2025 isn’t bad. He has options and could be sent back down to Tacoma once Donovan and/or Patrick Wisdom come off the IL.
As for Mastrobuoni, he started the season on the 10-day IL with a right calf strain. He began a minor league rehab assignment on April 8th and played as recently as the 18th. His current status is unclear but he must have suffered some sort of setback, since he’s now ineligible for reinstatement until late May.

Red Sox To Place Sonny Gray On Injured List
The Red Sox will place Sonny Gray on the 15-day injured list tomorrow, reports Chris Cotillo of MassLive. The veteran righty left this morning’s start with right hamstring tightness and is slated for an MRI on Tuesday. Rookie southpaw Tyler Samaniego will be recalled as the corresponding move to give Boston an extra reliever for the next few games.
Although the Sox won’t know the severity of Gray’s injury until tomorrow, they’ve expressed optimism. The pitcher and skipper Alex Cora each said they don’t believe it’s a serious injury. Gray missed time with strains of the same hamstring in 2022 and ’24. That history adds some confidence to his feel that this isn’t a major issue but also incentivizes the Sox to be cautious. He’ll be eligible to return on May 6.
Gray’s first season in Boston has been a mixed bag. He owns a 4.30 earned run average with a much diminished 13% strikeout rate over 23 innings. Gray struggled in his team debut against Cincinnati, rebounded with consecutive quality starts against San Diego and Milwaukee, then was knocked around for five runs over four innings in Minnesota last week. He had allowed one run over 2 2/3 innings in today’s start.
The early exit forced the Sox to lean heavily on their bullpen. They used seven relievers to hang onto an eventual 8-6 win over Detroit. Long man Jack Anderson, who threw three innings and 41 pitches yesterday, was the only reliever who didn’t get into today’s game. Boston has divisional series against the Yankees, Orioles and Blue Jays before their next off day on April 30. Samaniego hasn’t pitched since Friday, so he should be available for a couple innings tomorrow. He was just optioned back to Triple-A last week but can be recalled to replace an injured pitcher.
Boston’s schedule will require them to turn to a fifth starter this weekend unless they want to run a bullpen game. Top prospect Payton Tolle seems the logical candidate after making a late-season debut in 2025. The big lefty has recorded 19 strikeouts while allowing eight runs (five earned) through 15 Triple-A frames this year.
Tolle hasn’t pitched since April 12. Cotillo notes that the Sox scratched Tolle from his Triple-A start over the weekend in case he was needed at the MLB level with uncertainty about potential weather postponements and doubleheaders. Connelly Early, Ranger Suárez and Brayan Bello are lined up for the series against the Yankees. Boston hasn’t announced a probable starter for Friday’s opener with Baltimore, but Garrett Crochet would be on regular rest for that outing. Gray’s next turn would have come on Saturday.
Royals Place Jonathan India On IL With Shoulder Subluxation
The Royals announced that infielder Jonathan India has been placed on the 10-day injured list, retroactive to April 19th, due to a left shoulder subluxation. Infielder/outfielder Nick Loftin has been recalled as the corresponding move.
Per Anne Rogers of MLB.com, this is the same shoulder injury that India has battled in the past. On June 13th of 2025, he dove for a ground ball and clearly hurt himself, as seen in this clip from MLB.com. He suffered a subluxation at that time. He didn’t go on the IL for that shoulder but did occasionally miss time for the rest of the year.
India had a subpar season, though it doesn’t seem as though the shoulder injury explains the whole thing. He had a .249/.332/.336 line and 89 wRC+ through that June 13th game, followed by a .219/.315/.355 line and 89 wRC+ after it. He did have an IL stint in that latter section, but it was due to a left wrist sprain. He is out to a rough .167/.310/.313 start so far in 2026.
Whether it’s due to the injuries or not, the Royals surely hoped for more when they acquired India from the Reds ahead of the 2025 season. He slashed .253/.352/.412 with Cincinnati from 2021 to 2024, production which translated to a wRC+ of 108. After his rough 2025, he became a speculative non-tender candidate, but the Royals brought him back by signing him to an $8MM deal for this year.
So far, that investment hasn’t paid off. Ideally, India can get healthy and get back on track, though the next steps are unclear at this point. Per Rogers, India received an injection and will be seeing another doctor this week.
With India out of commission, the Royals will likely use some combination of Michael Massey and Loftin to cover second base. Massey started the season on the IL due to a calf strain and has hit .174/.208/.261 since coming back. That’s in a tiny sample of 24 plate appearances but he also hit .244/.268/.313 for a 57 wRC+ last year, so he hasn’t been in good form for quite a while. Loftin has 438 career plate appearances with a .220/.296/.323 line and 73 wRC+.
The Royals are out to a 7-15 start, tied with the Mets for the worst record in baseball. The team has a combined .218/.296/.339 batting line and 79 wRC+, which places them ahead of only the Reds among big league clubs. Though India has been struggling, it doesn’t appear that subtracting him from the lineup is likely to help matters.

Edwin Díaz To Undergo Surgery For Loose Bodies In Elbow
The Dodgers announced that right-hander Edwin Díaz has been placed on the 15-day injured list with right elbow loose bodies. A subsequent announcement said that he will have surgery to address the issue and is expected to return in the second half of the season. Reportedly, he’ll miss about three months, which will put him in line for a return sometime around the All-Star break. Left-hander Jake Eder has been recalled to take Díaz’s spot on the active roster.
The status of Díaz has been a bit of a mystery for a while now, as he has struggled for the Dodgers while pitching with diminished velocity. His fastball has averaged 95.7 miles per hour so far this year, a notable drop from his 97.2 mph average last year. His results were fine through five outings but his sixth, on April 10th, was rough. He entered a 7-4 game in the ninth and surrendered three runs, allowing the Rangers to tie it up.
The Dodgers were able to walk that game off in the bottom of the ninth but Díaz became a question mark. He didn’t pitch in official game action for over a week after that, even though the Dodgers had some save situations. He was finally back on the mound last night but the results were again poor. He entered in the bottom of the eighth at Coors Field, with the Dodgers down 6-4. He faced four batters, allowing three hits and a walk, then was removed without recording an out.
On the one hand, it’s nice to have a diagnosis that explains his struggles, but any elbow issue for a pitcher is going to be worrisome. Losing him for three months is going to be a blow. He has been one of the best closers in recent history and was just signed to a huge contract in the offseason. The Dodgers gave him a three-year, $69MM deal to scoop him away from the Mets.
The Dodgers have won the past two World Series but their 2025 title came despite a shaky bullpen. Manager Dave Roberts relied more and more on his starters as the postseason went along and the Dodgers just barely held on, as they almost lost to the Jays on a few occasions, going into extra innings in Game Seven.
The Díaz signing was supposed to patch over one of the club’s few weak spots as they look for a three-peat. Though Díaz isn’t quite as ridiculously dominant as he was a few years ago, he still had a great 2025 season, tossing 66 1/3 innings with a 1.63 earned run average 38% strikeout rate, 8% walk rate and 48.4% ground ball rate.
The Dodgers generally approach injuries with a long view. Their team is strong enough that they can feel quite good about their chances of making the postseason. They can have their players, particularly the pitchers, take their time to ensure they are healthy for the postseason. Given the three-month timeline, they can take that approach with Díaz. Ideally, he will be back in time to shake off some rust down the stretch and be in peak form for October.
Time will tell how that goes. If Díaz experiences any kind of setback or struggles to get in form once he is healthy, it could potentially impact how the Dodgers approach the trade deadline, which is on August 3rd this year.
For now, they will have to proceed without their big offseason bullpen investment. Tanner Scott, Alex Vesia and Blake Treinen could be candidates for picking up some save opportunities now. Scott is back in good form so far this year after a rough 2025. Vesia has picked up a few scattered saves over the years and has started 2026 with ten scoreless appearances. Treinen has past closing experience but isn’t out to a great start this year, with a 4.05 ERA thus far.
Alden González of ESPN reported that he would undergo surgery and be out about three months. Fabian Ardaya of The Athletic first reported that some kind of procedure would take place. Jack Harris of the California Post first reported that the Dodgers would expect him to be back from that procedure during this season. Photo courtesy of Jayne Kamin-Oncea, Imagn Images
Tyler Wade Granted Release By Rangers
Veteran infielder/outfielder Tyler Wade has been granted his release by the Rangers, reports Evan Grant of the Dallas Morning News. He’d signed a minor league pact with Texas over the winter and opened the season with their Triple-A club in Round Rock. Wade is now free to sign with any team.
The 31-year-old Wade is a versatile but light-hitting utility player who posted a .212/.296/.245 batting line in 283 plate appearances with the Padres over the past two seasons and carries a career .216/.294/.284 batting line (65 wRC+) in 992 turns at the plate in the majors. He’s gotten out to a slow start this year with Round Rock, slashing just .226/.315/.242 in 16 games/73 plate appearances. He’s suited up at five different positions: shortstop, second base, third base, left field and center field.
Wade has drawn solid marks for his big league glovework at second base and third base but has garnered shakier ratings at shortstop and across the outfield. He’s an above-average runner but doesn’t get on base frequently enough to make great use of that speed. In parts of seven Triple-A seasons, Wade is a .279/.359/.399 hitter.
Rays Select Trevor Martin
The Rays announced that they have selected the contract of right-hander Trevor Martin. He’ll take the active roster spot of fellow righty Mason Englert, who has been placed on the 15-day injured list due to right forearm tightness. To open a 40-man spot, righty Michael Grove has been transferred to the 60-day injured list.
Martin, 25, was a third-round pick of the Rays in 2022. Tampa used him as a starter in his first professional seasons but converted him to a reliever last year. From the start of 2025 to the present, he has thrown 62 2/3 innings, split between Double-A and Triple-A, having allowed 2.73 earned runs per nine. His 9.5% walk rate is a bit high but his 25.2% strikeout rate is a few ticks above average. He averages about 95 miles per hour on his fastball, per Statcast, while also featuring a cutter, splitter, slider and changeup.
That stat line includes 9 1/3 scoreless innings to start this year. He has worked around a 14.6% walk rate in the early going but putting up zeroes has seemingly attracted the attention of the front office. Martin gets the call for the first time and will make his major league debut as soon as he gets into a game.
Though Martin has done his part, the injury situation has played a role as well. Tampa lost Edwin Uceta and Steven Wilson to injuries in spring training. Since then, Garrett Cleavinger and now Englert have hit the IL as well. Manuel Rodríguez is still recovering from last year’s Tommy John surgery. Marc Topkin of The Tampa Bay Times relays that Englert and manager Kevin Cash don’t consider his injury to be serious, so perhaps he will be back relatively quickly. Martin has a full slate of options and could be shuffled between Triple-A and the majors as those guys get healthy or when fresh arms are needed.
As for Grove, he underwent shoulder surgery while with the Dodgers last year and missed the entire campaign. He was bumped off the roster at the end of the season and became a free agent. The Rays signed him last week and immediately placed him on the 15-day IL. His exact timeline isn’t clear but this transfer suggests the Rays don’t expect him to be back in the majors soon. He won’t be eligible for reinstatement until June.
