Jose Castillo

Mariners Designate José Castillo For Assignment

By Darragh McDonald | September 12, 2025 at 5:55pm CDT

The Mariners announced today that they have recalled right-hander Casey Legumina from Triple-A Tacoma. In a corresponding move, left-hander José Castillo has been designated for assignment. The club’s 40-man roster count drops to 39.

Castillo, 29, was just claimed off waivers from the Mets earlier this month. Since that claim, he has given the Mariners three scoreless innings. This move is likely more a result of circumstances than his performance. The Mariners are seven games into a stretch of ten in a row. The bullpen has been leaned on heavily in recent days. Five different relievers pitched on Tuesday. Then on Wednesday, six relievers were used in a game which went to 13 innings. Three of those six pitchers tossed more than an inning. Last night, the club had another long one, using six relievers in a 12-inning game.

Every reliever in the bullpen pitched at least twice in that three-day span except for Emerson Hancock, who logged two innings on Wednesday. Castillo himself pitched in each of the last two games and has seemingly been nudged out to get a fresh arm into the bullpen.

It’s been that kind of year for Castillo, who has generally pitched well. But since he’s out of options, he has been forced into DFA limbo numerous times. He started the year with the Diamondbacks on a minor league deal. He was added to the big league roster at the start of May. Less than two weeks later, he was designated for assignment and traded to the Mets. The latter club designated him for assignment three times. The first two resulted in him clearing waivers and later getting added back to the roster, but the M’s claimed him on the third.

He’s now back in DFA limbo yet again. Since the trade deadline has passed, he’ll be back on waivers in the coming days. Around all the transactions, he has tossed 24 2/3 innings with a 4.38 earned run average, 19.5% strikeout rate, 9.3% walk rate and 55.7% ground ball rate. He has also thrown 16 Triple-A innings this year with a 1.69 ERA, 35.9% strikeout rate, 9.4% walk rate and 50% grounder rate.

At this time of year, he wouldn’t be postseason eligible with any claiming club, though perhaps some team is in need of a fresh arm for the stretch run. As mentioned, Castillo just appeared in the past two games but will have a chance to rest for a few days while on waivers. He could also be retained for next year via arbitration if he’s on a roster somewhere at the end of the season.

Mariners Claim José Castillo, Designate Joe Jacques For Assignment

By Darragh McDonald | September 3, 2025 at 2:40pm CDT

The Mariners announced that they have claimed left-hander José Castillo off waivers from the Mets. The latter club designated him for assignment a few days ago. To open a 40-man roster spot, fellow lefty Joe Jacques has been designated for assignment. Castillo is out of options, so the M’s will need to make a corresponding active roster move once he reports to the team. Ryan Divish of The Seattle Times reported the claim prior to the official announcement.

Castillo, 29, has logged 21 2/3 innings this year between the Diamondbacks and Mets. He has allowed 4.98 earned runs per nine but with better underlying metrics. His 21% strikeout rate and 8.6% walk rate are both close to average, while his 52.9% ground ball rate is quite strong.

That performance hasn’t been enough to keep him in the majors for an extended stretch. Since he is out of options, he has been designated for assignment multiple times this year. Arizona gave him his first DFA of the season in May and then flipped him to the Mets for cash. Since then, the Mets have given him the DFA treatment three times. The first two resulted in him clearing waivers and sticking with the Mets, later getting selected back to the roster. Around the transactions, he also tossed 16 Triple-A innings with a 1.69 ERA, 35.9% strikeout rate, 9.4% walk rate and 50% ground ball rate.

On this third Mets DFA, the Mariners have swooped in to grab him. They already have three lefties in their bullpen, with Gabe Speier, Caleb Ferguson and Tayler Saucedo back there, but adding Castillo will give them even more balance in their relief corps. He has between four and five years of big league service time, so they can retain him for 2026 via arbitration if he still has a roster spot at season’s end.

Jacques, 30, signed a minor league deal with the Dodgers in the offseason. He was traded to the Mariners in early July. The M’s added him to their 40-man roster and then immediately optioned him to Triple-A. It’s likely that his deal with the Dodgers had some sort of opt-out or upward mobility clause. The Dodgers evidently weren’t willing to give him a 40-man spot but the M’s were.

In the minors this year, he has posted poor surface-level results with better underlying numbers. He has thrown 47 innings in the hitter-friendly Pacific Coast League with a 6.51 ERA. His 23.6% strikeout rate and 9.8% walk rate are close to par while his 59.7% ground ball rate has been quite good. He has seemingly been undone by a .393 batting average on balls in play and 57.7% strand rate, which are both on the unlucky side. His 4.61 FIP this year is far more optimistic than his ERA.

Despite the positive indicators, the M’s are moving on. Jacques is in his final option year and will therefore be out of options going into 2026. That would have made it harder for them to roster him going forward, so they are cutting him loose now.

Since the trade deadline has passed, he’ll be on waivers in the coming days. It some team believes he can post better numbers going forward, perhaps away from the PCL, then they could put in a claim. He can still be stashed in the minors for the rest of this year. He has less than a year of service time and theoretically has years of control, though as mentioned, he’ll be out of options next year. He has 29 2/3 major league innings with a 5.46 ERA, 15.9% strikeout rate, 8% walk rate and 61.9% ground ball rate.

Mets Designate Jose Castillo For Assignment

By Mark Polishuk | August 30, 2025 at 12:19pm CDT

The Mets announced that left-hander Jose Castillo has been designated for assignment.  Right-hander Chris Devenski was called up from Triple-A Syracuse in the corresponding move.  The transaction brings Devenski’s fresh arm into the bullpen, as Castillo tossed 47 pitches over a two-inning relief outing in Friday’s 19-9 rout of the Marlins.

Castillo is out of minor league options, and thus this is the fourth time this season he has been DFA’d since has to first clear waivers before being sent to Triple-A.  The first designation came in May when Castillo was still a member of the Diamondbacks, and the Mets then brought the southpaw into the organization via trade.  In Castillo’s previous two DFAs with New York, he cleared waivers and was outrighted to Syracuse.  It stands to reason that the same will happen here, though Castillo has the right to reject an outright assignment and elect free agency if he wants to explore the open market.

Despite the roster churn, Castillo has pitched quite well during his time in Queens, posting a 2.35 ERA, 53.3% grounder rate, 25.7% strikeout rate, and 8.1% walk rate over 15 1/3 innings with the Mets.  This represents Castillo’s best stretch in the majors since his 2018 rookie season, when he broke into the Show with a 3.29 ERA over 38 1/3 relief innings with the Padres.

However, Castillo tossed just two MLB innings between the 2019-24 seasons, due to a variety of injuries that included a Tommy John surgery.  His bottom-line numbers for New York provide some proof that the 29-year-old can still be effective against big league hitters, even if the Mets see him as an expendable arm.

Mets Place Reed Garrett On IL Due To Elbow Inflammation

By Darragh McDonald | August 25, 2025 at 2:45pm CDT

The Mets announced today that right-hander Reed Garrett has been placed on the 15-day injured list due to right elbow inflammation, retroactive to August 23rd. They have selected left-hander José Castillo to take Garrett’s place on the active roster. Righty Frankie Montas has been transferred to the 60-day IL to open a 40-man spot.

Garrett, 32, has been a key part of the Mets bullpen for about two years now. He broke out with a strong performance in 2024, tossing 57 1/3 innings with a 3.77 earned run average. His 12.1% walk rate was high but he struck out 33.6% of batters faced and got grounders on 44.3% of balls in play. He moved up the club’s pecking order, earning four saves and 14 holds.

He has largely kept that kind of performance going here in 2025. He has thrown another 52 1/3 innings with a 3.61 ERA, 28.3% strikeout rate, 11% walk rate and 39.1% ground ball rate. He has added another three saves and 20 more holds.

To this point, the Mets haven’t provided any details about his injury or how long they expect him to be out of action, but it’s a concerning development regardless. It’s always somewhat worrisome when a pitcher’s throwing elbow isn’t 100%. For the Mets, they have been hit hard by the injury bug this year, with a number of relievers requiring season-ending surgeries in the first half. The club bolstered the group ahead of the deadline by acquiring Ryan Helsley, Tyler Rogers and Gregory Soto.

Despite adding those reinforcements, the club has been struggling this summer. They have gone 7-14 in the month of August and are barely clinging to a playoff spot. They are holding the third and final Wild Card slot in the National League but are just 1.5 games ahead of the Reds.

Part of that is due to Garrett himself. He had a 2.87 ERA in the first half but that has been up to 5.52 so far in the second half. A lot of that seems to be luck. He had a 25.5% strikeout rate and 12.4% walk rate in the first half, with those figures improving to 36.2% and 6.9% respectively in the second half. However, his strand rate went from a fairly average 74.2% to 51% while his home run to fly ball rate went from 5.9% to 27.3%. Though his ERA almost doubled in the second half, his FIP had a far more modest jump from 3.22 to 3.73 while his SIERA actually made a significant improvement, going from 3.92 to 2.16.

Even if the recent struggles aren’t entirely due to misfortunate, the Mets surely don’t want to be losing more pitchers to the injured list, especially after the deadline when it’s harder to find external solutions. For Garrett personally, it’s also less than ideal as he’s just about to qualify for arbitration for the first time.

For now, the Mets will add Castillo to the roster. He started the season with the Diamondbacks but was designated for assignment in May. The Mets sent some cash to Arizona to bring him aboard. Since then, he has bounced on and off the roster. They have twice designated him for assignment and sent him through waivers. Each time, he has accepted an assignment to Triple-A Syracuse and later been added back to the roster.

Overall, he has thrown 18 2/3 innings in the big leagues this year with a 5.30 ERA. His 21.5% strikeout rate and 9.7% walk rate have been close to average. His 53.3% ground ball rate is quite good but perhaps a lot of those grounders have found holes, as his .421 batting average on balls in play is quite high. His 3.76 SIERA suggests he has deserved far better than the ERA would indicate. He has also thrown 16 Triple-A innings this year with a 1.69 ERA, 35.9% strikeout rate, 9.4% walk rate and 50% ground ball rate. He is out of options, which has contributed to his many roster moves this year, so it’s possible his grip on a spot will again be tenuous this time around.

As for Montas, his transfer to the 60-day IL is not a surprise. It was reported a few days ago that he has a “pretty significant” injury to the ulnar collateral ligament in his elbow. It’s unclear how his 2026 will be impacted but he won’t return in 2025, so this move was inevitable.

Outright Assignments: 7/31/25

By Mark Polishuk | July 31, 2025 at 11:00pm CDT

Here’s the rundown of a few outright assignments that were announced during the blizzard of roster moves taking place on deadline day…

  • Catcher Jacob Stallings cleared waivers, and elected free agency rather than accept an outright assignment to the Orioles’ Triple-A affiliate.  Baltimore designated Stallings for assignment earlier this week, and since he has been previously outrighted in his career, Stallings had the ability to opt for free agency this time around.  Stallings signed a minor league deal with the O’s last month when the team was dealing with a myriad of catching injuries, and he was selected to the active roster to appear in 14 games.  Now in his 10th big league season, Stallings has hit .134/.195/.168 over 129 combined plate appearances with the Orioles and Rockies in 2025.  While these struggles represent a low for Stallings, he has generally been a below-average hitter apart from an .810 OPS over 281 PA with Colorado last year.
  • The Mets outrighted left-hander Jose Castillo off their 40-man roster and assigned him to Triple-A Syracuse.  It is the second time in a little over a month that Castillo was DFA’ed and then outrighted, and he chose to accept his last assignment to Syracuse rather than test free agency.  After posting an ugly 11.37 ERA in 6 1/3 innings with the Diamondbacks, Castillo was traded to New York in mid-May and has pitched well when he has been in the big leagues, with a 2.19 ERA over 12 1/3 innings and 14 relief appearances.  This is Castillo’s first real sustained stretch of decent MLB results since his 2018 rookie season with the Padres, when he had a 3.29 ERA across his first 38 1/3 frames in the Show.
  • The Braves outrighted catcher Jason Delay to Triple-A Gwinnett.  Delay also has a past outright on his resume, but it isn’t yet known if he’ll accept the assignment or opt for free agency.  It wasn’t known that Delay had been designated for assignment, but the move isn’t too surprising, as the Braves are deep at catcher and Delay hadn’t seen any time on Atlanta’s active roster.  Delay has a .231/.295/.315 slash line over 373 PA in the majors, all with the Pirates from 2022-24.  The Braves acquired him from the Bucs in April to add depth when Sean Murphy was recovering from a broken rib.

Mets Designate Jose Castillo For Assignment

By Nick Deeds | July 27, 2025 at 2:35pm CDT

The Mets have designated left-hander Jose Castillo for assignment, per a club announcement. The move makes room for the addition of lefty Gregory Soto to the active roster. Soto was acquired from the Orioles on Friday.

Castillo, 29, debuted with the Padres all the way back in 2018. That rookie year saw him pitch to a 3.29 ERA with a 2.64 FIP in 38 1/3 innings of work while striking out opponents at a 34.7% clip. It was an impressive showing, but injuries and ineffectiveness limited Castillo to just three total outings in the majors over the next six seasons. He surrendered five runs on four walks while striking out three in two innings of work during those outings, though he posted decent numbers at the Triple-A level with a 4.32 ERA in 125 innings of work with a 29.1% strikeout rate during that time.

The lefty eventually resurfaced this year and has split his time between the Mets and Diamondbacks. His five outings in Arizona went quite poorly, as he surrendered eight runs on ten hits and three walks while striking out just three in 6 1/3 frames, but since joining the Mets back in May he’s looked much better with a 2.19 ERA and 2.76 FIP in 14 appearances. Castillo has already been designated for assignment and outrighted off New York’s roster once this season. He’ll now go through the waiver process again unless the Mets are able to work out a trade involving him prior to Thursday’s trade deadline. If he goes unclaimed on waivers once again, he’ll have the opportunity to either accept an outright assignment to the minor leagues from the Mets or elect free agency, at which point he would be free to sign with any of the league’s 30 clubs on a fresh contract.

Replacing Castillo on the roster is Soto who the Mets dealt a pair of prospects to Baltimore in order to acquire. The southpaw has a 3.96 ERA in 36 1/3 innings of work for the Orioles this year, with a 27.5% strikeout rate and a 3.28 FIP. A two time All-Star with the Tigers in 2021 and ’22, Soto was shipped to the Phillies prior to the 2023 season and has struggled during his time with Philadelphia and Baltimore since then, with a lackluster 4.53 ERA across the 2023 and ’24 seasons despite a tidy 3.63 FIP. The Mets will surely help that they can help him return to his prior All-Star caliber form so he can join the late-inning mix alongside closer Edwin Diaz, but even if Soto is little more than a league average middle relief arm for the club he’ll offer much-needed depth to a bullpen that has lost a half dozen relievers to the injured list already.

Mets Select José Castillo

By Darragh McDonald | July 25, 2025 at 3:10pm CDT

The Mets announced today that they have selected left-hander José Castillo to the roster. Right-hander Alex Carrillo has been optioned to Triple-A Syracuse in a corresponding active roster move. Righty Max Kranick has been transferred to the 60-day injured list to open a 40-man spot. It was reported a week ago that Kranick will require season-ending elbow surgery.

The Mets have been churning arms through their bullpen for a long time, thanks to a string of injuries, particularly to left-handers. They had planned on having A.J. Minter and Danny Young as their southpaw contingent in the bullpen but both required season-ending surgeries by the middle of May. Since then, they’ve also lost Kranick and Dedniel Núñez to the scalpel.

Castillo, 29, was one of the reinforcements. He was acquired from the Diamondbacks in mid-May, shortly after Minter and Young went down. He spent a little over a month on the roster, tossing 11 1/3 innings, allowing three earned runs despite giving up 16 hits, issuing six walks and hitting four opponents. He struck out 14 batters and got ground balls on 55.9% of balls in play allowed.

The Mets bumped him off the roster at the end of June and then passed him through waivers. He accepted an outright assignment and has since been pitching for Syracuse, allowing one earned run in 5 1/3 innings.

Not too long ago, the Mets activated Brooks Raley from the injured list, as he had recovered from last year’s Tommy John surgery. They acquired Gregory Soto from the Orioles earlier today. Now with Castillo coming back, they will have three lefties whenever Soto reports to the team. However, it’s also possible that Castillo gets bumped out again to make room for Soto at that point. The Mets could also make further relief additions between now and next week’s deadline.

Colin Poche Elects Free Agency

By Anthony Franco | July 1, 2025 at 9:54pm CDT

Veteran reliever Colin Poche elected free agency after being outrighted by the Mets, relays Laura Albanese of Newsday. Fellow southpaw José Castillo also went unclaimed and was outrighted off New York’s 40-man roster, according to the MLB.com transaction log. Castillo has the right to elect free agency as well, though it’s unclear if he intends to do so.

Poche and Castillo are part of a revolving door of Mets’ lefty relievers. That role has been in flux since the A.J. Minter and Danny Young injuries. They’re now operating with Richard Lovelady and Brandon Waddell in that capacity. Poche, who signed a minor league contract in early May, was only on the MLB roster for a few days. He made one appearance, retiring two of six batters faced and giving up a pair of runs. Poche spent the first month of the season with the Nationals, allowing 12 runs with more walks than strikeouts in 8 2/3 innings.

This has been a frustrating season for the 31-year-old in both MLB and (to a lesser extent) at the Triple-A level. He was a decent middle reliever for the Rays as recently as last year. Poche turned in a 3.86 ERA across 37 1/3 frames with Tampa Bay in 2024. The Mets could look to bring him back on a new minor league contract given their lack of depth from the left side.

Castillo landed in Queens in a DFA trade with the Diamondbacks. He got a longer run in Carlos Mendoza’s relief corps than Poche had. The 29-year-old made 13 appearances and allowed five runs (three earned) across 11 1/3 innings. He punched out 14 but issued six walks and plunked another four hitters. This has been Castillo’s first significant stretch of MLB action since he made 37 appearances during his 2018 rookie season with the Padres, largely because of various intervening injuries.

Mets Designate José Castillo, Richard Lovelady For Assignment

By Darragh McDonald | June 25, 2025 at 2:25pm CDT

The Mets announced that they have selected right-hander Jonathan Pintaro to the roster, a move that was reported yesterday, and recalled left-hander Brandon Waddell. In corresponding moves, they have designated left-handers José Castillo and Richard Lovelady for assignment.

The Mets opened the season with A.J. Minter and Danny Young as the lefties in their bullpen. They lost both of them before the end of April. Minter required season-ending lat surgery while Young required Tommy John surgery.

Shortly thereafter, the out-of-options Castillo was designated for assignment by the Diamondbacks. The Mets sent some cash to Arizona in order to skip the waiver queue. He has generally performed well since becoming a Met, having tossed 11 1/3 innings with a 2.38 earned run average, 24.1% strikeout rate, 10.3% walk rate and 55.9% ground ball rate.

Getting bumped off the roster today might simply be due to the club having a taxed bullpen, as they used all eight of their relievers in the past two days. Reed Garrett pitched on both days, including 22 pitches last night. Three other relievers on the club, including Lovelady, tossed 24 pitches or more last night.

They have added some fresh arms to the group today but Castillo has been bumped into DFA limbo, which can last as long as a week. The waiver process takes 48 hours, so the Mets could take as long as five days to explore trade interest.

Lovelady, 29, was just signed a couple of days ago. There was an amusing bit of confusion about his name when the Mets announced him as “Dicky” Lovelady. Per Anthony DiComo of MLB.com, the lefty does go by “Dicky” during casual interactions but will be referred to as “Richard” in official settings such as in print and on scoreboards.

He tossed an inning and two thirds for the Mets last night, allowing two earned runs via two walks and a hit, while striking out one. Like Castillo, he is out of options and has been bumped off the roster and into DFA limbo.

Prior to joining the Mets, he was in good form on a minor league deal with the Twins. He had tossed 20 2/3 innings at the Triple-A level with a 1.31 ERA, 26.5% strikeout rate, 8.4% walk rate and 60.4% ground ball rate.

The Mets now have no real lefty presence in the bullpen. Waddell is a southpaw but he’s likely to be used as a long reliever. Brooks Raley could join the club later in the season but is still recovering from last year’s Tommy John surgery. It seems fair to expect the Mets to be on the lookout for lefty relief help between now and the deadline.

Diamondbacks Trade Jose Castillo To Mets

By Anthony Franco | May 15, 2025 at 9:35pm CDT

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.
