Zack Wheeler On Track For Late April Return
Right-hander Zack Wheeler has been on the mend from thoracic outlet surgery since last September, with an early-season return being the goal for the Phillies. That could happen very soon, as Scott Lauber of The Philadelphia Inquirer reports that Wheeler will make one more rehab start for the Double-A Reading Fightin Phils on Sunday. If all goes well, he could rejoin the major league club next weekend for their series against the Braves.
At the time of the surgery, Wheeler’s recovery was expected to take 6-8 months. A return at the short end of that range would have brought him to the opening week of the season and left no time for a full ramp-up. Given that Wheeler has continued to pitch like an ace into his mid-30s, the Phillies were never going to risk bringing him back too early. That said, his recovery was progressing well overall, and manager Rob Thomson indicated last month that the club expected a return not “too far beyond” Opening Day. Evidently, the 35-year-old has shown enough in his rehab stint to rejoin the big-league rotation by the end of April.
Wheeler made 24 starts last year and was in top form the whole way. He posted a 2.71 ERA in 149 2/3 innings with a career-high 33.3% strikeout rate and just a 5.6% walk rate. That performance was good for 4.0 fWAR, which tied him for 11th among big-league starters despite throwing significantly fewer innings than usual. His dominance was interrupted by an IL stint in August for a right upper extremity blood clot, which led to the discovery of venous TOS and his subsequent season-ending surgery. Venous TOS is the less severe form of the injury, with the Diamondbacks’ Merrill Kelly being the best example of returning to form following surgery.
The Phillies are surely hoping Wheeler can do the same. Their rotation has performed unevenly through their first 19 games to the tune of a 5.55 ERA. While Cristopher Sánchez is dominating as usual and Jesús Luzardo and Andrew Painter are outperforming their surface numbers, Taijuan Walker has struggled badly through four starts. He allowed two earned runs in five innings against Arizona last week but has given up at least four earned runs in his other three starts. Most recently, he allowed seven earned runs on seven hits and three walks in just four innings against the Braves.
Though he’s likely to get one more start, Walker could lose his spot to accommodate Wheeler’s return, according to Lauber. That leaves Walker ticketed for a bullpen role, though he’ll surely get more starts throughout the year in the event of an injury. Walker made 17 relief appearances from 2024-25 with unspectacular results. Given his struggles so far in 2026, he’ll likely be limited to low-leverage spots.

Angels Recall Walbert Ureña, Option Sam Aldegheri
The Angels have announced that they’ve recalled right-hander Walbert Ureña from Triple-A. Lefty Sam Aldegheri is being optioned to Triple-A in a corresponding move.
Ureña returns to the big leagues after making two appearances during the club’s season-opening series against the Astros. That was the 22-year-old’s first big-league experience. Though he didn’t allow an earned run in 1 2/3 innings, he surrendered five hits and six unearned runs while also giving up three unintentional walks. He was optioned to Triple-A on March 29 and has since made two starts with a 6.48 ERA. He spent most of 2025 at the Double-A level, where he posted a 4.39 ERA in 27 starts along with an impressive 58.5% groundball rate.
The right-hander was signed as an amateur free agent out of the Dominican Republic in 2021. He currently ranks as the Halos’ No. 18 prospect according to MLB.com, although his inconsistent command has kept him from becoming a top prospect. Ureña has posted walk rates around 12% in the upper levels of the minors. While his scouting report lauds him for his plus fastball, his secondary pitches haven’t developed to the point where a long-term future as a starter seems possible. Still, he is very young and just debuted this year, so he has plenty of time to prove himself. Whatever his long-term role, Ureña’s success hinges on his ability to keep racking up groundballs while improving his secondary pitches enough to achieve an average strikeout rate.
Aldegheri’s demotion comes after just one appearance for the big-league club this season. He threw 33 pitches in Thursday’s win over the Yankees, striking out two while allowing one run on a solo homer. Since debuting in 2024, the 24-year-old has made a total of eight appearances (five starts) without much success. His 16.2% career strikeout rate puts him right around Ureña’s minor-league numbers, while his 14.2% walk rate is untenable against big-league hitters. Aldegheri had a 3.72 ERA in 23 starts at Double-A last year, but he hasn’t been able to put it together yet at Triple-A or in the majors.
Despite their struggles, both Ureña and Aldegheri should get their share of opportunities with the big-league club this year. The Angels’ bullpen ranks as a bottom-10 unit in the league by fWAR (-0.1) through April 17. The group’s 4.46 ERA ranks 18th in the league, and their 4.72 FIP suggests they’ve been somewhat lucky to achieve that performance. Brent Suter and Sam Bachman have done well, and Ryan Zeferjahn has made up for a subpar 4.82 ERA with stronger peripherals, including a 32.5% strikeout rate. The rest of the arms, including veterans Shaun Anderson and Drew Pomeranz, have struggled. Despite their 11-10 start, the Angels are still in a place where they will prioritize opportunities for young players over immediate contention.

Phillies Place Jhoan Duran On 15-Day Injured List
4:25 pm: Duran felt something in his side on Wednesday and again today when he got on the mound, reports Lochlahn March of The Philadelphia Inquirer. Thomson revealed that imaging showed a “very mild strain,” and the team hopes to have Duran back in the minimum 15 days, according to Todd Zolecki of MLB.com. In the meantime, Keller will get most of the closing opportunities.
1:52 pm: The Phillies announced five roster moves, with the most prominent being Jhoan Duran‘s placement on the 15-day injured list (retroactive to April 15) due to a left oblique strain. Right-hander Seth Johnson and utilityman Felix Reyes were brought up from Triple-A in other moves, with Reyes’ contract selected to the 40-man roster for the first time. Utilityman Otto Kemp was optioned to Triple-A, and outfielder Pedro Leon was released.
Duran hasn’t pitched since last Saturday, but since the Phillies went 1-4 with an off-day during that stretch, the lack of usage was thought to be due to game situations rather than injury. More details on Duran’s injury and the severity of the strain should surface later today once manager Rob Thomson meets with the media, but unless the closer has the very mildest of strains, Duran is likely looking at at least a month on the shelf.
It’s a big loss for a Phillies team that is off to an underwhelming 8-11 start. While the bullpen as a whole has been shaky, Duran has been a stabilizing force at the back end. The closer has a 1.35 ERA, 33.3% strikeout rate, and zero walks over 6 2/3 innings, while recording saves in all five of his opportunities.
There’s no obvious candidate to step into the ninth-inning role, so the Phils might explore a committee situation until Duran is healthy. Jose Alvarado has an ugly 10.50 ERA over six innings, though that number is inflated by a huge .450 BABIP and Alvarado has past closing experience. Brad Keller, Orion Kerkering, or Tanner Banks could also get some save chances depending on the in-game situation.
Kemp has gotten only 22 trips to the plate this season, but just two hits in that small sample size has led to a .282 OPS and a ticket back to Lehigh Valley. Taking Kemp’s spot as a multi-positional bench player is Reyes, who will be making his MLB debut as soon as he enters a game.
Reyes was an international signing for the Phillies in 2020, and he isn’t considered a top-30 Philadelphia prospect in the eyes of either Baseball America or MLB Pipeline. The 25-year-old didn’t even make his Triple-A debut until he played six games with Lehigh Valley in 2025, but he has burst out of the gates this season by hitting .333/.345/.654 with six home runs over 84 PA. This production comes on the heels of an impressive Double-A season in 2025 that saw Reyes named Eastern League MVP for his work (.335/.365/.572 with 15 homers and 13 steals over 395 PA) in Reading.
It’s probably unlikely that Reyes will hit anything close to that level against MLB pitching, yet the Phillies have nothing to lose by giving a hot hitter a chance in place of the unproductive Kemp. Reyes has experience in both corner outfield and corner infield slots, so the Phils might look to give Reyes some work at third base since Alec Bohm‘s bat has been ice cold.
Leon was claimed off the Orioles’ waiver wire back in November, and his brief time on the 40-man roster didn’t result in any looks on the active roster. Leon was hitting .285/.358/.326 over his first 53 PA at the Triple-A level this season, and while Leon still has a minor league option remaining, the Phillies may have just valued the 40-man slot over whatever they felt Leon could provide to the organization. The 27-year-old returns to the open market in search of another chance to build on his limited MLB resume of seven games and 21 PA with the 2024 Astros.
Diamondbacks Reinstate Lourdes Gurriel Jr., DFA Luken Baker
After suffering a torn right ACL on September 1, Lourdes Gurriel Jr. is ready for his return to the majors, as the Diamondbacks officially reinstated the outfielder from the 10-day injured list. To make room for Gurriel on the 26-man and 40-man rosters, first baseman Luken Baker was designated for assignment.
D’Backs manager Torey Lovullo hinted yesterday that Gurriel could be in Arizona’s lineup as soon as this weekend, completing what has been a remarkably quick comeback from such a serious knee surgery. Gurriel was projected to miss 9-10 months given the usual timeframe for ACL tears, yet he made such solid progress in Spring Training and in just two games of a minor league rehab assignment that the D’Backs felt comfortable in bringing him back after a little over seven and a half months.
Depending on how Gurriel’s knee holds up, he might end up getting fairly regular duty in his old left field position pretty soon, without the need for steady DH duty. Pretty much no matter where Gurriel plays, it was easy to project Baker as the odd man out of a roster crunch, as Baker has appeared in only three games (with five plate appearances) since his minor league contract was selected on April 7.
Arizona signed Baker to that minors deal in December, and possibly with an eye towards platooning Baker and Pavin Smith at the position. Carlos Santana was signed later in the season to fill that role, yet the first base situation was thrown into total flux shortly after Opening Day. Smith played in two games before being placed on the IL due to a balky elbow that has now required surgery, and Santana has also been out since April 6 due to an adductor strain.
Baker’s contract was selected in the wake of Santana’s injury, yet Baker didn’t get much opportunity due to the unexpectedly strong play of Jose Fernandez and utilityman Ildemaro Vargas in handling the first base duties. The D’Backs seem content to leave the position (and a share of the DH workload) to that duo, leaving Baker now exposed to the waiver wire.
If Baker clears waivers, he has the right to decline an outright assignment to Triple-A Reno in favor of free agency, since Baker has a previous outright in his career (last August, when Baker was in the Dodgers organization). The first baseman could opt to just move on given how Arizona’s first base picture has remained crowded, or another team might look to claim Baker just as the Dodgers did last August when the Cardinals parted ways with the 29-year-old.
Baker spent his first three MLB seasons in St. Louis, hitting .206/.317/.338 with four home runs over 189 PA. While his power hasn’t translated much against big league pitching and Baker is defensively limited as a first base-only player, he has posted good numbers at Triple-A, and could be viewed as at least a depth option.
Marlins To Activate Kyle Stowers On Sunday
The Marlins are about to get an All-Star back in their lineup, as manager Clayton McCullough told reporters (including Kevin Barral of Fish On First) that Kyle Stowers will be activated from the 10-day injured list before Sunday’s game with the Brewers. MLB.com’s Christina De Nicola wrote earlier today that Stowers is already at loanDepot Park but would probably get one final day of rest and examination before making his 2026 debut tomorrow.
Right hamstring tightness bothered Stowers for most of Spring Training, and he left one of the Marlins’ final Grapefruit League games with a Grade 1 hamstring strain that required a season-opening IL stint. The recovery period was initially estimated at 3-4 weeks, so Stowers will indeed make it back on the higher end of that projected timeline.
Stowers’ rehab assignment at Triple-A Jacksonville lasted five games, with three played in his usual left field position, one game at DH, and one game at first base. This marked Stowers’ pro debut as a first baseman, though he spent a bit of time at the position in college and in summer ball action (the West Coast League and Cape Cod League). McCullough recently indicated that Stowers might get some prep work at first base just in case the Marlins decide to incorporate him into the first base mix at the MLB level, both to help Miami out at a trouble position and to give Stowers some time at a lower-intensity position.
Stowers is the most high-profile of the five position players on Miami’s injured list, though Christopher Morel‘s absence due to an oblique strain has been the major cause of the team’s revolving door at first base. While the Marlins’ roster has been a little short-handed, the team’s offense hasn’t much suffered, as Xavier Edwards, Otto Lopez, Liam Hicks, and Connor Norby are all off to hot starts.
Needless to say, getting Stowers back will be a huge boost. Sunday will mark Stowers’ first MLB game since August 15, as his breakout 2025 campaign was cut short by an oblique strain. Stowers’ first full season in Miami saw him hit .288/.368/.544 with 25 home runs over 457 plate appearances, and he generated 4.0 fWAR over only 117 games.
The corresponding move for Stowers remains to be seen. Graham Pauley left yesterday’s game due to oblique discomfort and isn’t in today’s starting lineup, but McCullough told Barral and company that Pauley is expected “to be available today for whatever is needed.”
José Buttó Undergoes Procedure For Blood Clot
TODAY: Butto underwent his surgery yesterday, the Giants announced (hat tip to Susan Slusser). The right-hander’s recovery timeline has now been increased to 5-6 months, meaning that Butto’s 2026 season is almost certainly over.
APRIL 4: The Giants announced today that Butto’s recovery timeline is 2-4 months.
APRIL 3: Giants reliever José Buttó has a blood clot in his throwing arm, the team told reporters (via Alex Pavlovic of NBC Sports Bay Area). He’s undergoing a procedure this evening to remove it.
Buttó landed on the 15-day injured list yesterday. The team initially announced that only as arm fatigue. The clot provides a little more clarity, but there’s no return timeline. Susan Slusser of The San Francisco Chronicle relays that it appears Buttó had pitched through the issue for a while before the clot was diagnosed earlier today.
Blood clotting can be associated with thoracic outlet syndrome. That was the case for Phillies ace Zack Wheeler, for example. The Giants have not said anything about whether that’s a fear for Buttó. However, skipper Tony Vitello told Slusser there are a few possible procedures that the right-hander might undergo.
San Francisco acquired Buttó from the Mets as one of three players in the Tyler Rogers deal last summer. Blade Tidwell, another part of the Rogers return, was coincidentally recalled to take his place in the bullpen yesterday. Buttó turned in a 4.50 ERA across 20 innings down the stretch. He surrendered five runs on six hits and four walks over two innings to begin the 2026 season.
Astros Claim Dustin Harris, Designate J.P. France For Assignment
The Astros announced that outfielder Dustin Harris was claimed off waivers from the White Sox. To create space for Harris on Houston’s 40-man roster, right-hander J.P. France was designated for assignment, as reported by The Athletic’s Chandler Rome shortly before the team’s official announcement.
Houston has 10 pitchers on the injured list, so it is a little surprising to see the team part ways with France when he has a minor league option remaining. Lack of pitching depth aside, however, France didn’t do much to hang onto his spot by posting an 8.10 ERA over 6 2/3 innings and three appearances for the Astros this season. The Astros also already designated France and subsequently outrighted him off the 40-man roster back in February, before selecting his contract again on April 10 when Cristian Javier went on the IL with a grade 2 shoulder strain.
Because of that past outright, France has the ability to elect free agency if he clears waivers again. Given how he wasn’t claimed last time around and he hasn’t done much to improve his stock since Opening Day, France may well clear waivers and then decide on either testing the open market or accepting another outright to Triple-A. Given how the Astros are in such dire need of pitching, France might feel comfortable biding his time in the minors until Houston gives him another look.
France has spent his entire career in the Astros organization, beginning as a 14th-round pick in the 2018 draft. He broke into the majors with a solid 3.83 ERA over 136 1/3 innings and 24 games (23 of them starts) in 2023, but has since delivered a 7.00 ERA over only 36 big league frames, as shoulder problems sidelined France for the bulk of the 2024-25 seasons.
Beyond all of Houston’s pitching injuries, the loss of Jake Meyers (oblique strain) and Zach Dezenzo (right elbow sprain) also depleted what was already a thin outfield picture. Harris can provide some depth given his experience at all three outfield positions, and his left-handed bat adds some balance to a very right-handed Astros roster. However, fellow outfielders Joey Loperfido and Taylor Trammell are two of the three other lefty swingers on the 26-man, leaving Harris a bit of an imperfect fit in terms of platoon work.
Harris has played in each of the last three MLB seasons, hitting .224/.318/.414 with two homers over 66 plate appearances and 27 games for the Rangers and White Sox. After being outrighted off the Texas roster in November, Harris elected free agency and signed with the Sox on a minor league deal. Chicago selected Harris to the 26-man on April 7 and he got into six games for the team before being DFA’ed earlier this week.
NL West Notes: Susac, Bailey, Freeland, Dollander, Ryan
Daniel Susac went 2-for-5 in the Giants‘ 10-5 win over the Nationals yesterday, as the catcher is now hitting an absurd .524/.545/.714 over the first 22 plate appearances of his Major League career. Susac was a Rule 5 Draft pick initially from the Athletics organization before he was taken by the Twins and then immediately dealt to the Giants.
A big Spring Training performance clinched Susac’s roster spot and a role as Patrick Bailey‘s backup, yet Susac’s dream start is earning him more playing time, with starts in three of San Francisco’s last five games. On Thursday, Giants manager Tony Vitello told the San Francisco Chronicle’s Susan Slusser and other reporters that the team intends on “involving [Susac] as much as possible, see if we get into an every other day situation, or whatever it might be.”
Bailey has never shown much at the plate over his four MLB seasons, but he is off to a particularly ugly start by hitting only .128/.180/.128 in 50 PA. While Bailey’s elite defense has been reason enough to earn him starting catcher duties in the past, the Giants’ offense has struggled so much (Friday notwithstanding) that the club has nothing to lose by riding the hot hand in Susac.
More from around the NL West…
- Kyle Freeland‘s MRI on his inflamed left shoulder didn’t reveal any structural damage, Rockies manager Warren Schaeffer told the Denver Post’s Patrick Saunders and other reporters. Freeland was retroactively played on the 15-day injured list on April 13, and the good diagnosis means that the veteran southpaw likely won’t miss too much time. The injury interrupted Freeland’s strong start to the season, as he had a 2.30 ERA over his first three outings.
- Chase Dollander is another Rockies pitcher getting good early results, as the former third overall pick has a 3.32 ERA, 28.7% strikeout rate, and 7.5% walk rate over 19 innings. Dollander has yet to start any of his five appearances, however, and Schaeffer told Saunders and company that Dollander will continue pitching behind an opener for the time being. The manager’s logic is simple: Dollander is “having a lot of success” as a bulk pitcher. “He’s settled into a routine, and routines are very different from being in the bullpen and starting. Obviously, we want him to be a starter, long-term. But right now we don’t want to mess with the routine,” Schaeffer said.
- The Dodgers‘ Triple-A affiliate in Oklahoma City placed River Ryan on the seven-day injured list yesterday, and Jack Harris of the California Post indicated that the placement is likely due to a hamstring injury. Ryan posted a 1.33 ERA over his first 20 1/3 MLB innings in 2024, but a Tommy John surgery in August of that year sidelined the right-hander for the entirety of the 2025 campaign. Returning to action with Oklahoma City this year, Ryan’s excellent peripherals and a .450 BABIP over seven innings of work indicate that he has pitched much better than his 5.14 ERA would imply. The IL stint will delay his eventual return to Los Angeles in what will probably be a bullpen role, as there isn’t room for Ryan even in a six-man Dodgers rotation if everyone is healthy.
Cubs Select Corbin Martin’s Contract
11:39PM: The Cubs officially announced Martin’s selection and Horton’s move to the 60-day IL.
11:04AM: The Cubs will select the contract of right-hander Corbin Martin prior to today’s game with the Mets, The Athletic’s Patrick Mooney reports. Cade Horton (who underwent Tommy John surgery yesterday) will be moved to the 60-day injured list to open up a 40-man roster spot for Martin, and the Cubs already had an open spot on their active roster after Daniel Palencia was placed on the 15-day IL yesterday.
Horton and Palencia are two of a whopping 10 pitchers on Chicago’s injured list, leaving the Cubs scrambling for extra arms. The situation has given Martin a path back to the majors after the righty signed a minor league deal back in January.
Martin is himself no stranger to injuries, as he missed the entirety of the 2020 season due to a TJ surgery and all of 2023 recovering from a lat tendon surgery. In the wake of the latter procedure, Martin spent all of 2024 in the minors before making his return to the Show to post a 6.00 ERA over 18 innings with the Orioles last season.
Over parts of four MLB seasons, Martin has a 6.54 ERA, 20.7% strikeout rate, and 12.8% walk rate across 75 2/3 innings with the Astros, Diamondbacks, and Orioles. Since his lat surgery, Martin has worked almost exclusively as a relief pitcher, but the role change hasn’t helped alleviate the control problems that have plagued Martin for much of his career.
Martin is out of minor league options, so Chicago would have to designate the righty for assignment and expose him to waivers before trying to send him back down to Triple-A via an outright. Given how the Cubs are hurting for pitching, Martin probably won’t be DFA’ed any time soon if he can provide decent results and eat a few innings out of the pen.
Mets Place Jorge Polanco On 10-Day Injured List
The Mets announced that infielder Jorge Polanco has been placed on the 10-day injured list (retroactive to April 15) due to a right wrist contusion. Catcher Hayden Senger was called up from Triple-A in the corresponding move, and Senger is already on New York’s 40-man roster.
The wrist issue is a new injury for Polanco, who has been bothered by left Achilles soreness for most of the season. Polanco hasn’t played since Tuesday, and Mets manager Carlos Mendoza told the New York Post’s Mike Puma and other reporters that Polanco underwent an MRI on Thursday. The results of that MRI weren’t yet known yesterday, though the fact that Polanco’s IL placement is officially termed as just a contusion probably indicates that the MRI didn’t reveal any structural damage.
It could be that between Polanco’s wrist and Achilles problems, the Mets decided it was simply time to give the veteran a full recuperation period, as well as basically a reset to his 2026 season. After signing a two-year, $40MM free agent deal this past winter, Polanco has hit only .179/.246/.286 over his first 61 plate appearances in a Mets uniform. The Amazins’ plan was to use Polanco primarily as a first baseman, but he has played only two games in the field and the rest at DH due to his Achilles discomfort.
Polanco is far from the only struggling Mets player, as Friday’s 12-4 loss to the Cubs extended New York’s losing streak to nine games. Francisco Alvarez and (to a lesser extent) Luis Robert Jr. are the only Mets regulars hitting well in the early going, as Juan Soto‘s hot start was cut short by an IL stint due to a calf strain.
The lack of offense could be why the Mets called up Senger, even though Alvarez and Luis Torrens are already on hand as the catching core. Having a third catcher allows Alvarez to remain in the lineup on an everyday basis as either the catcher or the DH, and plus Senger is himself hitting .257/.316/.714 with five homers in only 38 PA for Triple-A Syracuse.
Even with this huge power surge, Senger’s career Triple-A slash line is still a modest .238/.295/.397 over 408 PA with Syracuse. The 29-year-old made his Major League debut in 2025, and hit .181/.221/.194 in 78 PA over 33 games with the Mets.
