Diamondbacks Trade Jose Castillo To Mets
The Mets acquired lefty reliever José Castillo from the Diamondbacks for cash, the teams announced. New York designated righty Kevin Herget for assignment to create a spot on the 40-man roster. Arizona had designated Castillo for assignment on Monday.
Castillo has technically appeared in five MLB seasons, though all but eight of his appearances came with the Padres during his 2018 rookie season. He turned in a 3.29 ERA over 38 1/3 innings that year but was subsequently set back by injury.
The 29-year-old signed a minor league deal with the Snakes in November. It marked his second consecutive season in the Arizona organization. He had spent all of last year with their Triple-A team in Reno, though he lost the first half of that season to injury. The Diamondbacks assigned him back to Reno to begin this season. He struck out seven while tossing 5 1/3 innings of one-run ball and was called up at the beginning of May.
The 6’6″ southpaw only spent a couple weeks in Torey Lovullo’s bullpen. He didn’t pitch well, allowing eight runs on 10 hits (including a trio of home runs) over 6 1/3 frames. Arizona bumped him out of the bullpen when Kendall Graveman returned from injury. Castillo is out of options, so they needed to designate him for assignment to take him off the MLB roster.
That out-of-options status means the Mets are prepared to give Castillo at least some time in their big league bullpen. They’ve been forced to scour the lefty relief market after losing Danny Young and A.J. Minter to season-ending injuries. They called up Génesis Cabrera from Triple-A Syracuse. He’s the only southpaw in Carlos Mendoza’s relief corps. Cabrera has managed five innings of one-run ball over four outings, but he had walked nearly 15% of opposing hitters in Triple-A before the promotion.
The Mets will need to remove someone from the major league bullpen once Castillo reports to the team. Dedniel Núñez is the obvious candidate, since he still has a couple options remaining. Cabrera is out of options, so the Mets would need to designate him for assignment if they wanted to use Castillo as their only left-hander.
Herget relinquishes his spot on the 40-man roster. The Mets claimed the 34-year-old off waivers from Milwaukee early last offseason. He only spent one day on the MLB roster, allowing two runs on three hits in one inning. He has otherwise been working out of the bullpen at Syracuse. Herget has only allowed five runs over 15 2/3 innings, but that came with a pedestrian 13:7 strikeout-to-walk ratio. He had a much stronger 32.4% strikeout rate over 38 appearances with Milwaukee’s top farm team a year ago.
The Mets will likely place Herget on waivers within the next few days. He has been outrighted twice in his career and would have the right to elect free agency if he goes unclaimed.
Rangers Release Adrian Houser
Righty Adrian Houser was granted his release from his minor league contract with the Rangers, the team announced. Jeff Wilson of DLLS Sports reports that Texas hopes to bring him back (presumably on a fresh minor league deal), but he’ll have the opportunity to explore other offers.
Houser signed with the Rangers during the offseason. He has worked out of the rotation at Triple-A Round Rock, tallying 39 1/3 innings across nine appearances. While his 5.03 earned run average is pedestrian, that’s not all that uncommon in the Pacific Coast League. Houser has stronger peripherals. He’s striking out a decent 22.8% of opponents while running an excellent 57.3% grounder rate.
Ground balls are Houser’s speciality. He has gotten grounders at a near-52% clip over parts of eight seasons in the majors. That was up in the 58-59% range during his best seasons with Milwaukee but has been down to a more normal 46-48% mark over the past few years. That caught up to him last year, as he allowed 5.84 earned runs per nine across 69 1/3 frames with the Mets. Houser had begun the season in New York’s rotation but was kicked to the bullpen after seven starts.
His results in relief were much better. Houser carried an ERA north of 8.00 as a starting pitcher but turned in a 3.28 mark across 35 2/3 relief innings. Texas seemingly preferred him as rotation depth, though it stands to reason he could find interest from other clubs as both a starter and reliever.
Huascar Ynoa Signs With Mexican League’s Leones De Yucatán
The Mexican League’s Leones De Yucatán announced that they have signed right-hander Huascar Ynoa. He had signed a minor league deal with the Minnesota Twins in the offseason but he was released last month, per his transactions tracker at MLB.com.
Ynoa, turning 27 this month, didn’t have a good tenure with the Twins. He made five Triple-A appearance but allowed five earned runs in 4 1/3 innings. He issued seven walks and hit a batter while only recording one strikeout. That poor performance seemingly led to his release. Now that he’s signing in Mexico, it seems he didn’t get much interest from the other affiliated clubs.
However, he is still relatively young and put up some good numbers a few years ago. With Atlanta in 2021, he tossed 91 innings with a 4.05 earned run average. His 26.9% strikeout rate, 6.7% walk rate and 47.3% ground ball rate were all better than average.
Unfortunately, he hasn’t been able to build off that solid season in subsequent years. In 2022, he had two bad starts to begin the year and spent most of the season in Triple-A, putting up a 5.68 ERA at Gwinnett. He required Tommy John surgery in September of that year, which wiped out his entire 2023. Last year, he missed more time due to a stress reaction in his elbow. He logged only 29 2/3 innings in the minors with a 6.37 ERA. He was non-tendered by Atlanta, which led to his minor league deal with the Twins.
After missing most of the 2023-24 seasons, it’s perhaps not shocking that Ynoa showed some rust to start this year. Ideally, the Leones can give him some time to get back into a groove and rediscover his previous form. If that comes to pass, he would likely have MLB clubs calling him up again.

White Sox Claim Vinny Capra
The White Sox announced that they have claimed infielder/outfielder Vinny Capra off waivers from the Brewers. He had been designated for assignment by Milwaukee last week. The Sox opened a 40-man spot recently by designating Gage Workman for assignment, so no corresponding move will be necessary there. Capra is out of options, so the Sox will need to open active roster space once he reports to the club.
Capra, 28, has been a good minor league performer in his career but hasn’t really had a chance to carve out a major league career. He has appeared in each of the four most recent major league seasons but has only been sent up to the plate 96 times over those campaigns. He has produced a dismal .105/.170/.163 line in those.
But on the farm, he received 1,287 plate appearances from 2021 to 2024. He drew walks in 11.4% of those while limiting strikeouts to an 18.6% clip. He had a combined .287/.376/.431 line and 118 wRC+ over those seasons. He also stole 25 bases while bouncing around the diamond. He has played every position except first base, though that includes just one inning as a catcher and just a third of an inning on the mound.
The Brewers apparently thought there was a chance of Capra being a useful big league player. They claimed him off waivers from the Pirates in 2023. Coming into 2025, he had exhausted his option years but earned an Opening Day roster spot by hitting .292/.358/.729 in spring training. However, he didn’t carry it over into the regular season, which nudged him off the roster and onto the waiver wire.
The Chicago roster is a bit of a motley crew right now. After losing 121 games last year, they are giving playing time to guys like Luis Robert Jr. and Andrew Vaughn, with the club hoping those guys can build trade value in the coming months. Meanwhile, guys like Miguel Vargas and Chase Meidroth are attempting to establish themselves as bonafide major leaguers and form part of the next core. Capra will jump in there and can bounce around to multiple spots. If he can get some plate appearances and produce some offense like he has in the minors, he’ll be a nice pickup for the Sox.

Giants, Drew Ellis Agree To Minor League Contract
The Giants are signing corner infielder Drew Ellis to a minor league deal. The move was announced by the Atlantic League’s Lexington Legends, where he had opened the season.
Ellis, 29, is a former second-round pick of the Diamondbacks. The Louisville product spent parts of two seasons with Arizona, batting .134 with 33 strikeouts in 97 plate appearances. He made a one-game cameo with the Mariners in 2022 and appeared in 12 contests for the Phillies the following year. That remains his most recent big league experience. Ellis spent some time in Triple-A with the Angels last season, posting a .243/.373/.414 line with almost as many walks as strikeouts in 134 plate appearances.
The right-handed hitter only spent two weeks with Lexington. He mashed over his 13 games, connecting on five home runs while batting .373 with nine walks and 11 strikeouts in 60 plate appearances. It was enough to get Ellis back into affiliated ball. He’s a career .247/.365/.490 hitter over parts of four Triple-A seasons.
Brewers Sign Eddie Rosario To Minor League Deal
The Brewers signed Eddie Rosario to a minor league contract and assigned him to Triple-A Nashville, relays Adam McCalvy of MLB.com. The Rimas Sports client had elected free agency after being designated for assignment by the Braves last week.
Rosario is already on his third organization of the season. He began the year in Triple-A with the Dodgers. He hit .339 with a pair of homers in 14 games to earn a brief call-up while Shohei Ohtani was on paternity leave. Rosario was DFA after two games because of Ohtani’s return. He elected free agency rather than accept an assignment back to Triple-A.
That led to a major league contract with Atlanta. Rosario replaced Jarred Kelenic as a lefty-hitting outfield bench bat for a couple weeks. He only started one game and went hitless with two strikeouts in four plate appearances. The Braves turned to speedy utility player Luke Williams for the final bench spot and dropped Rosario on Friday.
The veteran outfielder was a league average hitter back in 2023. He had a terrible ’24 campaign, combining for a .175/.215/.316 slash over 91 games between the Nationals and Atlanta. He’s a .221/.267/.379 hitter in more than 1100 plate appearances since his huge 2021 run that helped the Braves to a title.
Milwaukee is a bit shorthanded in the outfield. Blake Perkins has been out all year after suffering a Spring Training shin fracture. Garrett Mitchell went down with an oblique strain a few weeks ago. With Christian Yelich mostly limited to DH, Jake Bauers is working as Pat Murphy’s primary left fielder. Bauers is out to an excellent start to cement himself alongside Jackson Chourio and Sal Frelick as regulars. They’re a little more limited on the bench, where Isaac Collins and Daz Cameron as working as depth outfielders.
White Sox Return Rule 5 Pick Gage Workman To Tigers
Infielder Gage Workman has cleared waivers, and the White Sox have returned him to the Tigers, as reflected by his transaction log on MLB.com. He will report to Triple-A Toledo.
This hardly comes as a surprise after the White Sox designated Workman for assignment earlier this week. The Cubs initially selected Workman from the Tigers in the Rule 5 draft this past December. He made the Opening Day roster for the North Siders and suited up for the club in nine games over the first few weeks of the season. However, the Cubs no longer had a role for him after signing the much more experienced utility infielder Nicky Lopez to a big league deal in mid-April. Per the Rule 5 regulations, the Cubs could not simply option Workman to the minors, so they DFA’d him and traded him to the White Sox for cash considerations not long after.
Workman played just three games for the White Sox before landing on the IL with a right hip flexor strain. Upon reinstating him, the South Siders chose not to add him back to their active roster and DFA’d him instead. This time, evidently, no other teams were interested in giving him (and his .485 OPS through 17 PA) a spot on their active roster, so passed through waivers unclaimed. The White Sox then had to offer him back to the Tigers. As his original team, Detroit is not obligated to add him to its 26 or 40-man roster. He will return to the Tigers’ minor league system, where he thrived last year, hitting .280 with a 142 wRC+ in 126 games at Double-A.
Red Sox Place Tanner Houck On Injured List With Flexor Pronator Strain
The Red Sox have placed right-handed starting pitcher Tanner Houck on the 15-day injured list with a flexor pronator strain in his pitching arm. In a corresponding move, the team recalled fellow right-hander Cooper Criswell from Triple-A.
Following a strong 2024 season, Houck has not pitched well in 2025. Through nine starts, he is 0-3 with an 8.04 ERA. He has struck out just 32 batters in 43 2/3 innings, while walking 17 and hitting five. On two separate occasions, including his most recent outing on Monday, he has given up 11 earned runs in a start and failed to escape the third inning. If those two games were scratched from the register, his ERA would drop to 3.92, and his strikeout and walk rates would look much closer to what they were last season. But of course, there’s no pretending those blow-ups didn’t happen. Now, at least, Houck and the Red Sox might have an explanation for his struggles.
After Monday’s game, Red Sox manager Alex Cora told Chris Cotillo of MassLive that he was still trying to figure out why Houck had been so ineffective. “I’ve got to take a look at the video and we’ve got to see what we’re gonna do,” he explained. “Right now, it’s too fresh. It’s too quick. We have to take a look at it and see if it’s mechanical, usage, or where we’re at.” At that point in time, the skipper didn’t suggest the problem could be injury-related. Indeed, Cotillo notes that as recently as this afternoon, Cora continued to insist that Houck would start again this weekend. Now, Houck will not be able to return for at least two weeks. It’s unclear how long he’ll be out.
The Red Sox have not confirmed whether Criswell will make a start in Houck’s place. Criswell was more than serviceable as a starter last season, pitching to a 3.49 ERA and 4.21 FIP in 18 starts. While he failed to earn a rotation spot out of spring training, he has started his last four games at Triple-A to great success. In 20 2/3 innings, he has a 1.74 ERA with 27 strikeouts. Still, it’s possible he was called up to be an extra arm out of the bullpen instead. The Red Sox might prefer to move Sean Newcomb back from the bullpen into the rotation. After all, Newcomb beat out Criswell for a rotation spot on the Opening Day roster. Newcomb was also the reliever who came out of the bullpen and gave the team 5 2/3 strong innings on Monday after Houck’s early exit. In other words, he’s stretched out enough to start, and he’s on schedule to seamlessly take over for Houck.
There is also a chance the Red Sox won’t need either of Criswell or Newcomb to step up. They could skip Houck’s turn in the rotation and give the ball to Brayan Bello on Sunday, a course of action made possible by an off day on Thursday. Then, Walker Buehler, who is expected to be activated from the IL early next week (per Cotillo), could potentially make the start on Monday, giving Boston a rotation of Bello, Buehler, Garrett Crochet, Lucas Giolito, and Hunter Dobbins. This is only an option, however, if Buehler is ready to go by Monday. While the Red Sox are planning for him to rejoin the team at some point during their series with the Mets, it’s not yet clear if Monday is a realistic date for his return.
Astros Designate Tayler Scott For Assignment
The Astros have designated right-hander Tayler Scott for assignment, reports Chandler Rome of The Athletic. That’s the corresponding move for lefty Colton Gordon, whose promotion was reported earlier this week. Gordon was already on the 40-man, so this drops the club’s count to 39.
Scott, 33 next month, seemed to have a bit of a breakout with the Astros in 2024. After years of bouncing around to various major league clubs, minor league clubs, indy ball teams and a stint in Japan, he signed a minor league pact with Houston in December of 2023.
He made the Opening Day roster last year and went on to log 68 2/3 innings on the season, allowing just 2.23 earned runs per nine. His 12.4% walk rate was certainly on the high side but his 42.4% ground ball rate was around league average, while his 25.2% strikeout rate was a few ticks above par. He likely got a bit of help from his .230 batting average on balls in play and 84.9% strand rate, but even ERA estimators like his 4.13 FIP and 4.04 SIERA suggested he could be a useful bullpen arm even with a bit less luck.
Unfortunately, almost everything has gone in the wrong direction this year. Through 16 2/3 innings, he has a 5.40 ERA, 20.5% strikeout rate, 15.4% walk rate and 43.5% ground ball rate. That has clearly worn out Houston’s patience. Scott is out of options, so they had little choice but to bump him off the 40-man entirely.
Scott will now be in DFA limbo for a maximum of one week. The waiver process takes 48 hours, so the Astros could take five days to explore trade possibilities. Perhaps some club in need of bullpen help could be interested, if they feel there’s a way for Scott to get back to last year’s results.

Tigers Select Akil Baddoo, Option Jace Jung
The Tigers announced that they have selected outfielder Akil Baddoo to the 40-man roster. Infielder Jace Jung has been optioned as the corresponding active roster move. The 40-man roster already had a couple of vacancies, due to recently cutting Kenta Maeda and Manuel Margot, so no move was required to open a spot in that regard. Chris McCosky of Detroit News first reported that Baddoo was at the ballpark today and that Jung would be optioned for him.
Jung, 24, is a former first-round pick and top 100 prospect but the Tigers are still waiting for him to click at the big league level. He was promoted late last year and put up a serviceable .241/.362/.304 line in his first 34 big league games, though he did that while striking out at a 30.9% pace. The Tigers clearly weren’t fully convinced by that performance, as they made a strong push to sign Alex Bregman in the offseason, though he went to Boston instead.
Coming into this year, Jung struggled in the spring, hitting .121/.216/.273. He was optioned down to the minors prior to Opening Day but crushed it in Triple-A, slashing .239/.409/.463. That got him recalled three weeks into April but he hasn’t done much with the opportunity. His 28.3% strikeout rate is a slight improvement relative to last year but he has no extra-base hits, leading to a .111/.245/.111 line.
The Tigers apparently want him to work things out with more time on the farm, though he doesn’t have much left to prove there. He slashed .257/.377/.454 for a 123 wRC+ at the Triple-A level last year and, as mentioned, was good at that level for a spell this year. Still, it’s understandable that the club considers his current performance unacceptable for a competitive big league club.
The length of this optional assignment could be significant for Jung. He came into this year with 45 days of major league service time, putting him 127 shy of the one-year mark. He added another 23 days with this recent stretch in the majors but will need to come back up fairly quickly in order to have a shot at getting over that line. There are 137 days left in the regular season at this point.
Jung has been the club’s regular third baseman for past few weeks, so the club will need to come up with a new solution there. Javier Báez, Zach McKinstry, Andy Ibáñez and Trey Sweeney have also started games at third base this year. McKinstry and Báez have also been drawn into the outfield in order to cover for Detroit’s many injuries there, but Baddoo’s promotion will perhaps allow the club to shift some of those utility guys from the grass to the dirt.
Baddoo, now 26, seemingly had a breakout season in 2021. A Rule 5 pick, he hit 13 home runs, stole 18 bases and provided passable outfield defense. However, his bat cratered over the next three seasons. He hit .203/.292/.328 over the 2022 through 2024 campaigns.
That dropped his stock enough that the Tigers were able to pass him through waivers unclaimed in the offseason. He then required hamate surgery in February, putting him on ice during the spring. He has since recovered and has been performing well in Triple-A. He has a .245/.336/.471 line for a 123 wRC+ in 116 plate appearances, with six stolen bases to boot.
The Detroit outfield currently consists of Báez, McKinstry, Kerry Carpenter, Riley Greene and Justyn-Henry Malloy. Carpenter is often in the designated hitter slot while Báez and McKinstry could move to the infield a bit more now, as mentioned, which could open outfield playing time for Baddoo.
Matt Vierling is on a rehab assignment and could factor into the mix soon as well, either at third base or in the outfield picture. Baddoo still has an option and could be sent back down to the minors when Vierling is reinstated.
