Dodgers Sign José Ureña

By | at

8:03pm: Los Angeles officially announced the Ureña deal and reported DFA of Chuckie Robinson. They optioned Will Klein to Triple-A in a corresponding active roster move.

11:38am: The Dodgers are signing right-hander José Ureña, reports Jon Heyman of the New York Post. He’s expected to be in Los Angeles tonight to join their staff against the Mets, for whom he pitched earlier this year (albeit just one appearance). That suggests Ureña, a client of Premier Talent Sports & Entertainment, has agreed to a major league contract. Ureña is indeed getting a major league contract, per Alden González of ESPN.

Ureña, 33, just elected free agency yesterday. He’d been with the Blue Jays since early May and pitched reasonably well for Toronto but was cut loose when the Jays needed a fresh arm. He’ll at least temporarily join an injury-plagued Dodger bullpen that has seen significant turnover amid injuries to Evan Phillips, Kirby Yates, Blake Treinen and Luis García, among others.

Though Ureña’s time with the Jays resulted in a solid 3.65 ERA through 12 1/3 frames, he coupled that with an ugly 5-to-3 K/BB ratio and also served up three home runs. His 9.5% swinging-strike rate is noticeably south of the 11.3% league-average mark for a reliever, and opponents made contact on 88.8% of his pitches within the zone — a good bit higher than the 85% league average. Those red flags and the fact that he was on a minimal contract after signing under similar circumstances to the ones seen here with the Dodgers, made Toronto comfortable moving on.

Ureña throws hard but has a spotty track record in the big leagues. He was a solid starting pitcher with the Marlins early in his career, posting a 3.90 ERA in 343 2/3 innings from 2017-18. Declines in his command and his ability to keep the ball in the park plagued him for several years thereafter and caused him to begin to bounce around the league; from 2019-23, Ureña pitched a very similar number of innings to that ’17-’18 run  (350 1/3) but did so with a bleak 5.50 ERA while suiting up for five different clubs.

A 2024 stint with the Rangers revitalized Ureña’s career to an extent. He was a valuable swingman in Texas last season, piling up 109 innings with a 3.80 ERA and a much-improved 8.4% walk rate — albeit in conjunction with a 15.4% strikeout rate that ranked near the bottom of the league.

The Dodgers’ bullpen is in shambles, with Phillips recently learning he’ll require season-ending Tommy John surgery. That’s the most notable but hardly the only injury. Yates has missed more than two weeks with a hamstring strain. García hit the injured list over the weekend due to a groin strain. Treinen has been out since April due to a forearm strain. Michael Kopech and Brusdar Graterol haven’t pitched at all in 2025 — the former due to an offseason forearm strain and the latter due to offseason shoulder surgery.

With the relief corps reeling, the Dodgers have recently brought in a fresh wave of arms. Lou Trivino, like Ureña, was signed after being cut loose by another club (the division-rival Giants, in Trivino’s case). He’s been excellent in 8 1/3 innings. Righty Ryan Loutos was acquired from the Cardinals in exchange for cash after being designated for assignment. Another righty, Will Klein, joined the team just yesterday after the Dodgers and Mariners swapped minor league arms; Seattle picked up lefty Joe Jacques from L.A. in that deal. Chris Stratton briefly signed in L.A. after his release in Kansas City but has since been designated for assignment. Former Reds closer Alexis Diaz was also added in a recent trade, though he’s in Triple-A Oklahoma City at the moment.

The Dodgers will need to open a 40-man spot for Ureña. They’re currently at capacity in that regard, and while they’ve had a mountain of injuries pile up they’re currently without a clear candidate to move to the 60-day IL. If the Dodgers think Diaz’s salary will allow him to pass through waivers, they could designate him for assignment and try to stash him in Triple-A that way. Loutos struggled in his lone MLB inning but has been sharp in Triple-A since his acquisition. Righty Noah Davis, a depth pickup back in March, has struggled both in OKC and in the majors, which could put him at risk as well.

Mets Recall Ronny Mauricio

By | at

4:45pm: As expected, Vientos has been placed on the 10-day IL with a right hamstring strain, per Will Sammon of The Athletic.

8:45am: The Mets are calling infielder Ronny Mauricio back up to the majors for what’ll be his first MLB action since 2023, as first reported by Mike Rodriguez. Mauricio missed the entire 2024 season after suffering an ACL tear during winter ball in the 2023-24 offseason and began the 2025 season on the injured list as he finished up his rehab from the resulting knee surgery.

Mauricio’s return to the big leagues dovetails with a potential injury for third baseman/designated hitter Mark Vientos, who left last night’s game with discomfort in his hamstring after running out a grounder in the 10th inning. Skipper Carlos Mendoza noted after the game that it “didn’t look good” for Vientos following that exit and added that the slugger went straight to have imaging performed. The results of that MRI haven’t yet been shared publicly, but Mauricio traveling to Los Angeles to meet the Mets certainly seems to suggest an IL stint for Vientos could be forthcoming.

Still just 24 years old, Mauricio has ranked among the Mets’ top prospects for upwards of six years now. Originally signed out of his native Dominican Republic eight years ago, he’s had a relatively slow climb to the majors — granted, in large part due to that injury — but now looks poised for an opportunity of some note. He received a 26-game cup of coffee late in the 2023 season and batted .248/.296/.347 in his first 108 MLB plate appearances. Were it not for last year’s knee injury, Mauricio very likely would’ve gotten a larger opportunity in 2024.

The question of how to juggle playing time and opportunities for the promising young infield group of Mauricio, Vientos, Brett Baty and Luisangel Acuña has loomed over the Mets for some time, but that quartet has never been healthy enough simultaneously to force the issue. Early this season, Baty increasingly looked to be the odd man out, but he shook off a slow start and has been hitting well enough to cut into Vientos’ time at third base. After collecting only three hits in his first 10 games of the season, Baty has tallied 101 plate appearances with a hearty .280/.330/.548 slash (146 wRC+). He’s homered six times and added three doubles, two triples and a pair of stolen bases along the way.

As Baty’s bat heated up, both Vientos and Acuña cooled. Acuña’s month of May was even rougher than Baty’s first week-plus; he hit .204/.252/.222 last month and is hitless in three plate appearances since the calendar turned to June. Vientos, meanwhile, carried above-average production at the plate into mid-May, but he’s batted just .191/.250/.298 in his past 52 turns at the dish. All the while as that balance of playing time shifted in the majors, Mauricio was reacclimating to the rigors of pro ball and readying for another opportunity — one that now looks to have presented itself.

Mauricio posted an awful .125/.176/.188 line with a 35.3% strikeout rate in his first 10 games back from the injured list, which were split between Class-A and Double-A. With his rehab complete, the Mets unsurprisingly optioned him to Triple-A rather than call him up after that performance in the lower minors. A return to Triple-A Syracuse coincided with a return to form at the plate. Mauricio has played in nine Triple-A games and collected multiple hits in seven of them. He’s ripped three homers and a double, all while drawing the same number of walks as strikeouts (five) in 39 plate appearances.

The Mets would probably have preferred to see Mauricio draw out this hot streak a bit longer — both given the extent of his initial struggles in the low minors and because he’s yet to play on three consecutive days at any point in his return to action. He’s only played on consecutive days six times since his return to the field on April 27. The Vientos injury likely forced the Mets’ hand, however. Mauricio may end up in a limited role early on, sharing time at third base with Baty, at second base with Acuña and Jeff McNeil, and at DH with Starling Marte.

White Sox Notes: Cannon, Teel, Quero

By | at

The White Sox announced Tuesday that righty Jonathan Cannon has been placed on the 15-day injured list due to a lower back strain. Right-hander Caleb Freeman is up from Triple-A Charlotte to take Cannon’s spot on the active roster.

Cannon, 24, was sharp through his first nine trips to the hill this season (3.60 ERA, 18 K%, 7.8 BB% in 50 innings) but has run into a rough patch of late. Over his past trips to the mound, he’s been roughed up for 13 runs on 17 hits and four walks in 13 2/3 innings. Yesterday’s outing against the Tigers was particularly shaky; Cannon surrendered five runs — on the strength of three homers — and walked three batters in just three innings. A recent velocity drop could underscore the fact that he’s been pitching at less than 100 percent; Cannon averaged 93.5 mph on his four-seamer and 93 mph on his sinker through May 18 but has averaged just 91.8 mph and 92 mph, respectively, since.

The South Siders haven’t yet said how long Cannon will be out. Bruce Levine of 670 The Score reports that the Sox have already had imaging performed but have not yet publicly disclosed the results. It’s also not clear who’ll replace Cannon in the rotation. The Sox are currently going with Shane Smith, Davis Martin, Sean Burke and Adrian Houser in an all-righty rotation. Swingman Bryse Wilson is stretched out enough that he tossed five innings yesterday in relief of Cannon, but he’s sitting on a 6.80 ERA this year — including 17 earned runs in his past 14 2/3 innings.

Chicago’s depth chart has thinned out in recent months. Prospects Ky Bush and Drew Thorpe are out for the season after undergoing Tommy John surgery this spring. Other once-well-regarded prospects like Jairo Iriarte, Nick Nastrini, Owen White and Wikelman González have all struggled in the upper minors. Veteran southpaw Martín Pérez is out until at least September and could miss the rest of the year due to a flexor strain.

Lefties Noah Schultz and Hagen Smith are two of the top pitching prospects in all of baseball, but neither has even reached Triple-A yet; Smith only has 25 Double-A frames under his belt. The Sox probably want both to get more development time in before bringing them to the majors — particularly since neither needs to be added to the 40-man roster this offseason in order to be protected from the Rule 5 Draft.

The South Siders do have a top prospect who’s making a compelling case for a call to the majors sooner than later, but it’s not one of their coveted young arms. Catcher Kyle Teel, the headline prospect in the trade sending Garrett Crochet to Boston, is hitting .289/.394/.491 in Triple-A (131 wRC+). Teel has walked in a massive 14.8% of his plate appearances, fanned at a 26.6% clip that the Sox would surely like to bring down, clubbed eight homers and even swiped seven bags in eight attempts.

A consensus top-50 prospect in the sport, Teel got out to a slow start this season but has only been held hitless four times in 34 games dating back to an April 12 doubleheader where he went 0-for-3 in both halves of that twin bill. In 134 plate appearances since that time, the 2023 first-rounder (No. 14 overall) is batting .331/.428/.532. Strikeouts remain an issue, and Teel’s .378 average on balls in play isn’t sustainable, but it’s hard for him to do much more to clamor for a call to the majors.

The Sox, it seems, are taking notice. Teel tells Scott Merkin of MLB.com that the organization has begun to have him work out at first base. Teel hasn’t played there in a game yet but has been taking grounders at first base the past few days and working with the staff in Charlotte to acclimate himself to a new position.

Chicago recently optioned longtime first baseman Andrew Vaughn to Charlotte. The former No. 3 pick has been a constant in their lineup for four-plus seasons but has never lived up to expectations when he was one of the top prospects in his draft class. Vaughn has been a roughly average offensive performer with poor glovework and baserunning. The Sox are surely hoping he can get on track in Triple-A and salvage some value later this summer, but sending him down and getting Teel some looks at first base signal a clear shift in the team’s plans.

Teel probably isn’t an option to be the Sox’ everyday first baseman moving forward. He’s regarded as a viable defensive catcher who blocks balls in the dirt and throws well. He’s nabbed 33% of would-be base thieves this season. Baseball Prospectus also gives him solid framing marks behind the dish in the minors.

That said, the Sox entered 2025 with two of baseball’s top catching prospects: Teel and former minor league teammate Edgar Quero. It was Quero who received the first call to the majors, and he’s held his own, hitting .248/.336/.301. That’s about 13% worse than league-average overall, per wRC+, but not far off the average line posted by catchers in 2025. Quero has walked in 10.2% of his plate appearances against a 16.4% strikeout rate that’s about six percentage points better than average. He’s also making plenty of hard contact, but too much of it is resulting in grounders rather than line-drives or fly-balls. For a player whose sprint speed ranks in just the seventh percentile of MLB hitters, per Statcast, that’s not a good batted-ball trait.

Quero started quite strong and had a league-average batting line as deep into the season as May 25, so it’s not as if he’s been a lost cause at the plate. He’s in the midst of a dreadful 6-for-38 stretch, but he’d hit well prior to this slump. A cold streak spanning all of two to three weeks isn’t going to change the organization’s long-term view of Quero. The Sox are still hopeful that Quero and Teel can be their catching tandem for the next several years, and Teel getting some reps at first base only makes it easier for the Sox to get both into the lineup — assuming Teel handles the drills at first base reasonably well.

Blue Jays Designate Michael Stefanic, Ali Sánchez

By | at

The Blue Jays have designated infielder Michael Stefanic and catcher Ali Sánchez for assignment, per a team announcement. Their spots on the roster will go to second baseman Andrés Giménez and catcher Tyler Heineman, who have formally been reinstated from the injured list.

Stefanic, 29, appeared in nine games for the Jays after Giménez hit the injured list and went 4-for-22 with four singles, three walks and three strikeouts. That marked the fourth season in which he’s logged big league time but the first that he’s done so for any team other than the Angels. Stefanic has appeared in 99 MLB games and batted .227/.314/.267 in 289 trips to the plate.

For all his struggles in limited big league time, Stefanic has excelled at the top level in the minors. He’s played parts of five Triple-A seasons and touts a .344/.436/.468 batting line in a hefty sample of 1568 plate appearances. Stefanic has drawn 190 walks in Triple-A (12.2%) against just 147 strikeouts (9.7%). He has nearly 3000 career innings at second base and about 700 innings of work at both shortstop and third base. He’s regarded as a poor defender at each spot, however, and offers below-average grades in both power and speed as well.

The 28-year-old Sánchez went 2-for-11 with a double in his short time with the Jays. He was selected to the major league roster when Heineman hit the 7-day concussion injured list. This is Sánchez’s fourth season with a brief big league appearance, but he’s never tallied more than 31 games or 96 plate appearances at the major league level in a given season. He’s a .176/.217/.222 hitter in 43 MLB games/121 plate appearances.

Though he’s never hit in his limited MLB time, Sánchez is regarded as a quality defensive backstop with a nice track record at the plate in Triple-A. He’s played parts of six seasons there and turned in a .266/.338/.399 batting line. It’s not exactly standout production, particularly in typically hitter-friendly Triple-A settings, but Sánchez puts the ball in play at a better-than-average clip and walks in nearly 10% of his plate appearances in Triple-A; for a catcher with a sound defensive skill set, that’s decent production — certainly enough to make him a quality No. 3 or No. 4 catcher on a team’s depth chart.

The maximum length of the DFA window for either Stefanic or Sánchez is seven days. The Jays are free to explore trades or place them on waivers along the way, although since waivers are a 48-hour process, they’d need to have a trade lined up within five days or else go the waiver route with either or both players.

Rockies Make Several Roster Moves

By | at

The Rockies announced a slate of roster moves Tuesday, reinstating young righty Chase Dollander from the 15-day IL and placing fellow right-hander Tanner Gordon on the 15-day IL in his place, due to a strained left oblique. Gordon’s IL placement is retroactive to May 31. Colorado also placed righty Zach Agnos on the bereavement list and recalled right-hander Angel Chivilli. Additionally, infielder Aaron Schunk and outfielder Nick Martini cleared waivers and were assigned outright to Triple-A Albuquerque, per the MiLB.com transaction log. Martini elected free agency. Schunk has the right to do the same, by virtue of a prior outright assignment earlier this year, but there’s no indication he’s done so.

Dollander, 23, was the No. 9 overall pick in 2023 and entered the season ranked as one of baseball’s top pitching prospects. He’s had a handful of rough starts since making his MLB debut in April but looked to be righting the ship prior to landing on the IL due to forearm tightness. Dollander held opponents to two runs or fewer in three of his four appearances prior to the injury and had rattled off 10 2/3 innings with three runs allowed (2.53 ERA) and a 13-to-5 K/BB ratio in a pair of road starts against the Rangers and D-backs.

Dollander will slot right back into the Rockies’ rotation and start tonight’s game in Miami, per the team. As one might expect, the right-hander has been far better on the road in his young career than at Denver’s hitter-friendly home park. Dollander has made four starts at Coors Field and four on the road, working to an 8.66 ERA at home compared to a 4.29 mark in other venues. Overall, he carries a 6.28 ERA with a roughly average 22.1% strikeout rate, an elevated 10.5% walk rate and a massive 2.33 HR/9 mark (with six of his ten home runs allowed coming at home).

The 27-year-old Gordon was a sixth-round pick by the Braves back in 2019. He landed with the Rox alongside reliever Victor Vodnik in the trade that sent Pierce Johnson to Atlanta a couple years back. Gordon was rocked for an 8.65 ERA in eight starts during last year’s debut campaign but has provided a more serviceable 4.24 ERA with a 14.1% strikeout rate, 4.2% walk rate and 41.4% grounder rate in three starts (17 innings) so far in 2025. The team didn’t specify the severity of Gordon’s strain, nor was a timetable for his return provided.

Martini, 34, was designated for assignment last week. He totaled 111 plate appearances as a Rockie and hit .225/.288/.294 despite being deployed almost exclusively in platoon-friendly situations. Only five of the lefty-swinging Martini’s plate appearances came versus southpaws.

Over a six-year span from 2018-23, Martini batted .268/.362/.412 with an 11.2% walk rate in 412 plate appearances in the majors. He’s always walked at a huge clip and has been an on-base machine in the upper minors, playing parts of eight Triple-A seasons churning out a .294/.399/.454 batting line in that time. He’ll be a depth option for teams looking for left-handed bats, but he’ll probably need to sign a minor league deal after struggling at the plate in both 2024 and 2025.

The 27-year-old Schunk went 6-for-28 with a double in 29 plate appearances in his second year of partial MLB work with Colorado. The 2019 second-round pick hit .234/.265/.330 in 98 big league plate appearances last year. Schunk shows solid contact skills in Triple-A and has played all four infield spots — primarily third base — but doesn’t walk often or provide much power.

Schunk is a career .291/.346/.469 hitter in 880 Triple-A plate appearances, but given the intensely hitter-friendly nature of the Pacific Coast League (and Albuquerque’s home park, in particular), that’s actually about 12% worse than league-average, by measure of wRC+. Assuming he sticks with the organization, he’ll give the Rockies some righty-hitting infield depth at multiple positions.

Shane Bieber Targeting Return In Late June

By | at

Former American League Cy Young winner Shane Bieber could be back in the Guardians’ rotation before the end of the month. The 30-year-old righty, who underwent Tommy John surgery last April, began a minor league rehab assignment Saturday when he pitched 2 1/3 innings for the Guards’ Rookie-level affiliate in the Arizona Complex League and punched out five of nine opponents.

Bieber’s next start is slated to come at the Double-A level on Thursday, reports Zack Meisel of The Athletic, who adds that Bieber will likely take “about four weeks, give or take a few days” before returning to the majors (barring any setbacks). The maximum length for a pitcher’s rehab stint is generally 30 days, so with Bieber already making one rehab start last week, it’ll likely be a few days shy of that four-week mark. Pitchers recovering from Tommy John surgery can get up to three 10-day extensions to that rehab window with approval from the league and MLBPA.

If the Guards indeed plan to use around a 30-day rehab window, as Meisel implies, Bieber could make six rehab starts, with a final appearance on June 25 (or thereabouts) before being reinstated on the 29th and making his big league return on the 30th. Alternatively, they could bring him back into the MLB fold around that June 25 mark if things go smoothly. The specifics of his return will depend on how he fares in the weeks ahead, but Guardians fans can begin building up anticipation now that there’s a clock underway (again, barring any setback that would result in Bieber being pulled back from rehab).

Bieber made only two starts in 2024, his final season of club control in Cleveland, before incurring his ill-timed injury. That’s not to say there’s ever a “good” time for a player to suffer a UCL injury of course, but doing so just two weeks into one’s platform year before reaching the open market is particularly sub-optimal. That’s all the more true given that the right-hander looked brilliant in those two outings as he looked to rebound from a pedestrian 2023 showing. Bieber’s average fastball had ticked back up to 92 mph after sitting 91.3 mph in each of the past two seasons, per Statcast. His heater had been particularly limited in April in the 2022-23 seasons, sitting under 91 mph in both. That made the velo uptick all the more encouraging.

Bieber didn’t allow a run in 12 innings last year, and he struck out a comical 20 of his 45 opponents (44.4%) against just one walk (2.2%). Fifty percent of the balls put in play against him were grounders. It was a sample of just two starts, granted, but it’s hard to draw up a better beginning to a pitcher’s walk year — or a worse finish than what quickly transpired thereafter.

Had Bieber enjoyed a healthy season, he might’ve been able to command a nine-figure contract on the open market. Instead, he returned to the Guards on a two-year contract that guarantees him $26MM. The second season of that contract is a player option, however, so Bieber’s return effort merits a watchful eye. He’s being paid $10MM this season and has a $16MM player option with a $4MM buyout that he’d receive upon declining. As long as he’s confident he can top a one-year, $12MM deal — which seems overwhelmingly likely, so long as he’s healthy — Bieber will head back to the open market at season’s end. The Guards could then make him a qualifying offer.

Cleveland’s rotation has struggled without its typical top starter, ranking 22nd in the majors with a collective 4.16 ERA. The Guardians also just lost right-hander Ben Lively, who leads the rotation with a 3.22 ERA, to his own Tommy John procedure. Gavin Williams and Tanner Bibee have posted nearly identical 3.79 and 3.86 ERAs, respectively, though the former is doing in spite of an ugly 13.2% walk rate he’ll need to improve if he hopes to sustain a sub-4.00 ERA. Logan Allen (4.31 ERA) and Luis Ortiz (4.40 ERA) have both made at least 10 starts and held their own, though Allen’s 16.4% strikeout rate and 11.4% walk rate make his performance feel a bit suspect. Offseason trade acquisition Slade Cecconi has been in the rotation recently, making two very good starts to begin his Guardians tenure before a rocky third outing (five runs in 4 1/3 innings). He’s sitting on a 5.28 ERA in 15 1/3 innings overall.

All five current members of the Cleveland rotation can be optioned, which gives the Cleveland front office some flexibility once Bieber is ready to return.

MLBTR's Steve Adams hosted a live chat today, at 2pm CT, exclusively for Trade Rumors Front Office subscribers.

Steve Adams

  • Good afternoon! I'll get this started at 2:30pm CT, but feel free to send in some questions ahead of time if you prefer!
  • Greetings all! Let's get underway a bit early

Mrs Murphy

  • Is it time to wave the white flag in Atlanta? This offense is just a lost used to be.What’s next for them?

Steve Adams

  • Quite a few questions like this from Braves fans, and understandably so, given the poor performance of late, but I generally don't think it's too late for almost any team in MLB, with the obvious exceptions (Rox, Marlins, White Sox, probably the O's and A's).

    Atlanta is 5.5 back in the Wild Card chase and "only" four games under .500, which is pretty remarkable when you consider the early struggles and all the time they've had without Strider and Acuña.

    Heck, the 2021 Braves were three under .500 at the deadline, and they went on to win the World Series. The Mets and Astros were 10 under .500 this time last year. The 2019 Nats and 2022 Phils were buried even further.

  • I was underwhelmed by the Braves' offseason, and losing Profar to a PED suspension is brutal, but it's still a talented core with plenty of winnable series on the near horizon. They get the Rockies, A's, Angels, Orioles, Marlins and a currently struggling D-backs club all before the All-Star break.

Marlins Outright Matt Mervis

By | at

Marlins first baseman Matt Mervis passed through waivers unclaimed following his recent DFA and has been assigned outright to Triple-A Jacksonville, reports Craig Mish of SportsGrid and the Miami Herald.

Mervis, 27, generated some buzz among Marlins fans when he homered six times in an eight-game stretch early in the season. Even during that blistering hot streak, however, he fanned in 39% of his plate appearances. The lefty-swinging slugger has always had good power but has never made contact in the majors. Mervis’ lack of hit tool and poor swing decisions caught up to him quickly after that power surge. From April 17 through his DFA in late May, he slashed .125/.213/.213 with a 36% strikeout rate and only one home run.

This is the third season in which Mervis has seen big league time. He’s tallied 261 plate appearances between the Cubs and Marlins but managed only a .165/.238/.322 batting line (53 wRC+) due in large part to a 34.5% strikeout rate. His 66.9% contact rate in that time ranks 470th out of 485 big leaguers (min. 250 plate appearances).

In parts of four Triple-A seasons, Mervis has fared far better. He’s a .269/.371/.511 hitter in 1045 plate appearances and, more encouragingly, has only fanned in 23.3% of his plate appearances there. He’ll spend time in Jacksonville continuing to work on his plate discipline and swing decisions. There’s little doubting Mervis’ power; he bashed 36 home runs in the minors back in 2022 and has connected on 73 round-trippers over his past 1369 plate appearances in the minors. Miami doesn’t have anyone firmly blocking him at first base, so if he can make some gains in Triple-A, another look could be in store for him later this season.

D-backs Release Joe Mantiply

By | at

The Diamondbacks released lefty Joe Mantiply after his recent DFA, per their transaction log at MLB.com. Assuming he clears release waivers, he’ll be a free agent who can sign with any team tomorrow afternoon.

Mantiply, 34, has been a frequent presence in Arizona’s bullpen dating back to 2021. From ’21-’24, he pitched 198 1/3 innings with a 3.63 ERA, a 22% strikeout rate, a 6.1% walk rate, a 51.9% grounder rate, 50 holds and three saves. In 2022, specifically, he was one of the team’s most frequently used relievers in high-leverage spots.

The 2025 season has been an abject disaster for Mantiply, however. He fired a perfect inning in his first appearance of the season and immediately tanked thereafter. By the time Arizona optioned Mantiply to Triple-A Reno on April 19, he’d been tagged for a calamitous 13 runs in just 7 1/3 innings across eight relief outings. He got another look in mid-May and was quickly optioned again after surrendering four runs in 2 1/3 innings.

Even Mantiply’s time in Triple-A was generally a struggle. He allowed four runs in his first appearance with Reno and five in his final one. Those ugly outings bookended a strong run of 9 2/3 shutout innings, but the overall results were grim. In 9 2/3 MLB frames this year, Mantiply has a 15.83 ERA. He’s posted a 5.56 mark in 11 1/3 Triple-A innings.

Mantiply has always been a soft-tosser, but his fastball has bottomed out in 2025, averaging a career-low 88.2 mph. He sat 91.3 mph with the pitch back in 2021-22, when he was at his best, and was at 89.5 mph last year. He’s still filling up the strike zone, but doing so with diminished stuff has yielded diminished returns.

By all accounts, Mantiply is healthy at the moment. Teams are always in need of left-handed bullpen help, and Mantiply has a generally solid track record in the majors, so he ought to get another chance to turn his season around with a new club before too long. He’ll almost certainly need to pitch his way back to the majors on a minor league deal, however. He’s being paid $1.7MM this year, and the D-backs will remain on the hook for the rest of that salary — minus the prorated minimum for any team he spends with another club’s big league roster.
