Astros, Tom Cosgrove Agree To Minor League Deal
The Astros are in agreement with lefty reliever Tom Cosgrove on a minor league contract, reports Jon Heyman of The New York Post. The CAA client gets a non-roster invite to MLB camp and would be paid at a $900K rate if he makes the team.
Cosgrove has pitched in the majors in each of the past three seasons. The majority of his experience came in his rookie year with the Padres. He tallied 51 1/3 innings of 1.75 ERA ball in 2023. His underlying numbers weren’t nearly as impressive, and Cosgrove hasn’t gotten much of an MLB look in the past two seasons. He was blitzed for 19 runs across 14 2/3 innings in ’24. The Padres designated him for assignment and sold his contract to the Cubs last April.
The 29-year-old only made two appearances in a Cubs uniform. He worked four innings of one-run ball with three strikeouts and a walk. Chicago ran him through waivers in early September. Cosgrove finished the season with a 4.53 ERA across 49 2/3 Triple-A frames. He punched out a quarter of opponents but walked almost 13% of batters faced. He elected minor league free agency at year’s end.
While Houston has lacked left-handed relief depth over the past few seasons, that looks like a strength after last year. Josh Hader will be back in the ninth inning. Steven Okert and Bennett Sousa are coming off career years, while Bryan King had an impressive first full season in his own right. Cosgrove probably doesn’t have a path to an Opening Day job barring multiple Spring Training injuries. All of Houston’s previous non-roster invitees were right-handed, though, so it’s sensible to add at least one southpaw to the camp mix.

Cubs Outright Tom Cosgrove
The Cubs sent lefty reliever Tom Cosgrove outright to Triple-A Iowa, according to the MLB.com transaction log. He cleared waivers after being designated for assignment on August 31. Cosgrove was the 40-man roster casualty when the Cubs claimed Aaron Civale off waivers from the White Sox.
Chicago acquired Cosgrove from the Padres in the middle of April. He has spent most of the season in the minor leagues. The 29-year-old has made two big league appearances, allowing one run in four innings. The Manhattan University product has a 4.71 ERA across 42 frames with Iowa. Cosgrove has fanned a quarter of opponents but walked too many hitters, issuing free passes at a 14% clip.
Cosgrove pitched 51 1/3 innings of 1.75 ERA ball for San Diego two years ago. He hasn’t gotten much major league work since then. His Triple-A production over the past couple seasons has been middling as he has struggled to throw strikes consistently. This is Cosgrove’s first career outright assignment. He doesn’t have the requisite service time to elect free agency, so he’ll stick with Iowa as non-roster bullpen depth for the rest of the season. Cosgrove will become a minor league free agent at year’s end if the Cubs don’t call him back up.
Cubs Claim Aaron Civale
The Cubs have claimed right-hander Aaron Civale off waivers from the White Sox, according to a team announcement. Left-hander Tom Cosgrove was designated for assignment to make room for Civale on the 40-man roster. In addition the White Sox announced that they’ve selected the contract of right-hander Bryse Wilson to replace Civale on the club’s active and 40-man rosters.
Civale, 30, made his big league debut with Cleveland back in 2019 and posted a 3.77 ERA across 76 starts with the organization, but is now on his fifth team in the past three years as he’s changed hands between Cleveland, Tampa, Milwaukee, and now both Chicago teams. His numbers haven’t been nearly as good since he left the Guardians; since he was traded to Tampa, he’s pitched to a lackluster 4.78 ERA in 59 appearances with a 4.53 FIP and a 22.1% strikeout rate against a 7.5% walk rate. The numbers have been even less impressive this year, as he’s posted a 5.26 ERA with a 4.60 FIP in 16 starts between the Brewers and White Sox this year.
All of that might make it seem somewhat surprising that a Cubs team with designs on making it back to the postseason for the first time in a 162-game season since 2018 would have interest in his services. Despite Civale’s middling results, however, he’s still an appealing addition for Chicago thanks to the fact that he can log reliable innings for the club and help keep their top pitchers fresh ahead of the postseason. 2025 All-Star Matthew Boyd has already logged 153 1/3 innings this year despite having last thrown even 80 innings in a single season all the way back in 2019. Meanwhile, rookie Cade Horton has racked up 127 1/3 frames between Triple-A and the majors despite having never even thrown 90 innings in a season before.
Those heavy workloads could come with consequences by the time October rolls around, and USA Today’s Bob Nightengale reported this morning that the Cubs are already keeping a close eye on Boyd’s workload after he posted a 4.10 ERA in his last seven starts. Horton, meanwhile, has been among the very best pitchers in baseball since the All Star break with a 0.86 ERA in eight starts, but even he has thrown more than 74 pitches in just one of his six starts during the month of August. With Horton and Boyd likely to join Shota Imanaga at the front of Chicago’s rotation for the playoffs, it would make sense for the Cubs to try and ease off the gas for those players while leaning on their depth for the stretch run.
The problem with that plan is that Chicago’s depth has been taxed heavily by injuries. Front-of-the-rotation lefty Justin Steele has been out almost the entire year due to UCL surgery, and since then the Cubs have also lost both Jameson Taillon and deadline addition Michael Soroka to the injured list. Javier Assad has looked quite good since returning from his own stint on the injured list, but other arms will need to join him in helping lift up the front of the rotation if the Cubs are going to be able to rest Boyd and Horton this September.
That’s where Civale comes in, as he can join with other back-end starters and swingmen the Cubs have at their disposal like Assad, Ben Brown, and Colin Rea to help take the load off of Chicago’s projected playoff starters. At the very least, he should be able to serve as a capable bridge to players like Soroka and Taillon, who may be activated off the injured list before the end of the regular season. It’s also possible the Cubs will be able to get something more than innings out of Civale, given his past success and the solid enough 4.28 FIP he posted during his time with the White Sox.
In exchange for Civale’s services, the Cubs will pay the remainder of the right-hander’s $8MM salary for the 2025 campaign. That should free up some money for the White Sox as they look ahead towards the 2025-26 offseason and hope for better days next year. It will also provide opportunities for other arms to step into the rotation and show what they can do ahead of the offseason. Perhaps that will include Wilson, who was outrighted off the White Sox roster back in June after surrendering a 6.95 ERA in 45 1/3 appearances. Now that he’s back on the roster, perhaps Wilson will be able to finish the season strong at the big league level as he heads towards what will likely be free agency in the offseason, unless he pitches so well that the White Sox are convinced to tender him a contract for 2026.
As for Cosgrove, the lefty has a 2.25 ERA across four appearances with the Cubs this year after spending most of the season at Triple-A. He’s logged 70 big league innings in total over the past three years, the majority of which came as a member of the Padres, and in that time he’s pitched to a 3.86 ERA with a 4.07 FIP. The Cubs will have one week to try and pass Cosgrove through waivers, at which point they’ll have the opportunity to assign him outright to the minors if he goes unclaimed.
Cubs Promote Cade Horton
May 10: The Cubs have officially selected Horton’s contract, according to a team announcement. Left-hander Tom Cosgrove was optioned to Triple-A to make room for Horton on the active roster, while right-hander Eli Morgan was transferred to the 60-day injured list due to an inflamed ulnar nerve in his right elbow.
May 8: The Cubs are promoting pitching prospect Cade Horton, per reporting from Patrick Mooney and Sahadev Sharma of The Athletic. Tommy Birch of The Des Moines Register first reported this afternoon that Horton was traveling to New York in advance of this weekend’s series against the Mets. The young righty is not yet on the club’s 40-man roster, so they will need to open a spot for him.
Chicago’s rotation has taken a few notable hits recently. They came into the season with Justin Steele and Shota Imanaga as a one-two punch atop the rotation. Unfortunately, Steele required UCL surgery last month, putting him out of action for the rest of the year. Imanaga suffered a hamstring strain a few days ago. He is surely facing a far shorter absence than Steele but has been placed on the 15-day IL, meaning he’ll miss at least a few turns through the rotation.
Those are the two most obvious losses, but the clubs has also been without Javier Assad all year. He started the season on the 15-day injured list due to an oblique strain. He started a rehab assignment last month but re-aggravated the same muscle, suffering a Grade 2 strain.
Those injuries have created an opening for Horton to make it to the majors for the first time. The Cubs have “TBD” listed as their starter for Saturday’s game at Citi Field, which will seemingly be when Horton takes the ball. It seemed the decision on Imanaga’s rotation spot came down to promoting Horton or stretching out veteran swingman Chris Flexen.
Horton is the higher-upside play. Chicago selected him out of Oklahoma with the seventh overall pick in 2022. The 6’1″ righty has been the organization’s top pitching prospect over the past few seasons. His arsenal is headlined by a mid-90s fastball and a slider that grades as a plus pitch. Horton’s fastball velocity had dipped slightly to the 94 MPH range last year but has rebounded to sit at 95.8 MPH on average with Triple-A Iowa this season.
The 23-year-old has been out to an excellent start in Triple-A. Horton carries a 1.24 ERA while striking out nearly 31% of batters faced through 29 innings. He’s issuing walks at a lofty 12% clip, but the high-octane stuff will get him an opportunity to step into Imanaga’s rotation spot. If Imanaga makes it back within a few weeks, it might be a brief call-up, but the Cubs could theoretically push Ben Brown or Colin Rea to the bullpen if Horton forces their hand with a strong showing over his first few starts.
It’s too late for Horton to reach a full year of service time the traditional way. He meets the necessary prospect criteria to qualify for the Prospect Promotion Incentive, however. That means he could earn a full service year if he finishes in the top two in NL Rookie of the Year balloting. The Cubs would not receive a bonus draft choice if that happens because they didn’t promote Horton early enough to spend 172 days in the majors.
Cubs Acquire Tom Cosgrove From Padres
The Padres announced that they’ve dealt reliever Tom Cosgrove to the Cubs for cash considerations. Chicago designated righty Caleb Kilian for assignment to create a 40-man roster spot. San Diego had designated Cosgrove for assignment over the weekend.
Cosgrove, 28, was drafted by the Padres in 2017. San Diego added him to the 40-man roster during the 2022-23 offseason, a testament to the bat-missing ability he’d shown in the minors. Cosgrove made his major league debut the following April and managed strong numbers as a rookie. He turned in a 1.75 earned run average through 51 1/3 innings. His strikeout and walk profile was pedestrian, but he very rarely allowed hard contact and pitched well against lefty and righty batters alike.
The pendulum swung dramatically in the other direction last year. Cosgrove gave up 19 runs in 14 2/3 MLB innings spanning 18 appearances. Opponents’ average exit velocity jumped by three ticks while his strikeout rate dropped from 21.5% to 19.7%. Cosgrove spent most of the season in Triple-A, where he posted a 4.85 ERA with an above-average 26.8% strikeout percentage in 32 appearances.
Cosgrove did not break camp after a rough Spring Training, in which he gave up seven runs through 5 1/3 frames. He has gotten out to a slow start in Triple-A as well, allowing three runs with four walks and two strikeouts in four appearances. The Cubs immediately optioned him. He’ll begin his Chicago tenure with their top affiliate in Iowa. This is his final minor league option year.
Kilian is in his last option season as well. The Texas Tech product was a decent prospect in the San Francisco farm system whom the Cubs acquired in the Kris Bryant deadline deal in 2021. Chicago also acquired outfield prospect Alexander Canario, whom they DFA and traded away a couple months ago. It’s possible they’ll lose Kilian via trade or waivers within the next week.
The 27-year-old righty never established himself on Chicago’s staff. He has made five starts and three relief appearances going back to 2022. Kilian owns a 9.22 ERA in 27 1/3 innings thus far. He has issued 20 walks while recording only 21 strikeouts. Kilian has better numbers over four seasons at the Triple-A level. He carries a 4.37 ERA with a slightly below-average 21.8% strikeout rate across 274 innings at the top minor league level. Most of that has come as a starter. Kilian has only started one Triple-A game so far this season. He was tagged for six runs on a trio of homers in 2 1/3 innings.
Padres Select Logan Gillaspie, Designate Tom Cosgrove
The Padres announced that they have selected the contract of right-hander Logan Gillaspie from Triple-A. In corresponding moves, left-hander Omar Cruz was optioned to Triple-A, and left-hander Tom Cosgrove was designated for assignment.
Gillaspie first joined San Diego’s organization as a waiver claim off the Red Sox roster in November 2023, and he tossed 11 1/3 MLB innings (to a 7.15 ERA) last season. The Padres didn’t tender him a contract after the season, but then re-signed Gillaspie to a minors deal in December, and the righty has 2 2/3 innings of 6.75 ERA ball under his belt at Triple-A El Paso so far in the young minor league season.
Gillaspie is out of minor league options, so he’ll have to be designated for assignment the next time the Padres want to send him back to the minors. This could happen in relatively short order, as it would seem like Gillaspie has been promoted just to give San Diego a fresh arm in the bullpen. Cruz tossed 68 pitches over three innings of relief in yesterday’s 6-4 loss to the Cubs, and the Padres don’t have another off-day until Thursday. It wouldn’t be a shock to see Cruz recalled before the week is over, and once he’s had time to rest up from his extended outing.
Cosgrove is the other pitcher involved in today’s set of roster moves, and the 28-year-old heads to DFA limbo for the first time in his pro career. A 12th-round pick for San Diego in the 2017 draft, Cosgrove had an excellent 1.75 ERA in 51 1/3 innings during his 2023 rookie season, though secondary metrics indicated that Cosgrove enjoyed a lot of good fortune in managing that stellar ERA.
The luck turned in the other direction last season, as Cosgrove had only an 11.66 ERA in 14 2/3 big league innings, and he also struggled at the Triple-A level. In 2025, Cosgrove got off to another rough start, with a 7.36 ERA and four walks in his first 3 2/3 innings of work in El Paso. It was enough to make him the odd man out on the Padres’ 40-man roster, and Cosgrove will have to accept an outright assignment if he clears waivers since he doesn’t the service time or the past outright on his resume that would allow him to reject the assignment in favor of free agency.
Padres To Select Elias Diaz
The Padres are set to select the contract of catcher Elias Diaz tomorrow, according to a report from Kevin Acee of the San Diego Union-Tribune. Acee writes that Diaz will take the active roster spot created for a position player by tomorrow’s roster expansion, while left-hander Wandy Peralta will be activated from the 15-day Injured List to take the spot created for a pitcher. Lefty Tom Cosgrove will also be recalled from the minor leagues, though a corresponding move will be necessary to add him to the active roster. A corresponding move to make room on the 40-man roster will be necessary to accommodate Diaz.
Diaz, 33, joined the Padres on a minor league deal earlier this week after being released by the Rockies earlier this month. That release brought to an end a five-season stretch in Colorado that saw Diaz slash a solid .253/.305/.403 in 462 games with the club. That slash line was good for a wRC+ of just 80 due to the inflated offensive environment at Coors Field, but even that diminished figure is still well within the acceptable range for a glove-first catcher. Diaz proved to be a solid if unspectacular regular for the club behind the plate, even earning an All-Star appearance last year.
After a solid start to the 2024 campaign, the Rockies reportedly entertained trade offers for Diaz’s services, but the club’s plans to deal the veteran in his final year before free agency were thrown off course when he suffered a calf strain that caused him to miss three weeks in June. After returning, Diaz’s offense took a nosedive with a .194/.239/.239 slash line in 18 games in the run-up to the deadline. That seemingly scared off suitors to the point where the Rockies weren’t able to get a deal done, and it left them to try placing Diaz on waivers in mid-August in an attempt to find a suitor willing to absorb what remained of his salary. His offensive production had only improved marginally when the calendar flipped to August, however, and the club eventually released Diaz to allow him the opportunity to try and catch on with a contender elsewhere.
He’s now done just that with the Padres, and will have the opportunity to share catching duties with the club’s existing tandem of Luis Campusano and Kyle Higashioka down the stretch. Higashioka is in the midst of a career year at the plate with an excellent .230/.276/.520 slash line and 16 homers in just 215 trips to the plate, while Campusano has endured a bit of a down season with a slash line of just .233/.283/.372 in 87 games. Diaz should offer the club a solid defensive option behind the plate who, if he can regain his early season form, could offer an on-base ability that both of their current catchers lack.
As for Peralta, the veteran lefty has pitched to somewhat middling results in the first year of a complex four-year deal he signed with the Padres this winter. In 34 innings, the 32-year-old hurler has posted a 4.50 ERA despite a 5.70 FIP and a strikeout rate of just 13.6%. He’ll join fellow lefties Tanner Scott, Yuki Matsui, and Adrian Morejon in the club’s bullpen down the stretch, where the club will surely hope for Peralta to recapture the form that allowed him to post a 3.01 ERA in 200 appearances with the Giants and Yankees over the past four seasons.
Padres Select Austin Davis
3:30pm: The Padres have made it official, announcing they have selected Davis to the roster. Left-hander Tom Cosgrove was placed on the 15-day injured list with left elbow inflammation to open an active roster spot. To get Davis onto the 40-man, right-hander Joe Musgrove was transferred to the 60-day IL. Musgrove has a bone spur in his right elbow and has been on the IL since May 29. He’s now ineligible to return until 60 days from that date, which would be late July. He still hasn’t begun a rehab assignment and will need a few weeks to build up once he does.
11:29am: The Padres are planning to call up left-hander Austin Davis prior to tonight’s series opener against the Red Sox, reports Kevin Acee of the San Diego Union-Tribune. They’ll need to formally select his contract from Triple-A El Paso and open a spot on the 40-man roster, though that can be accomplished in rather straightforward fashion by transferring Xander Bogaerts (who’s out with a fracture in his shoulder) from the 10-day IL to the 60-day IL.
The 31-year-old Davis hasn’t pitched in the majors since 2022 but has appeared in parts of five MLB seasons. He’s posted a lackluster 5.61 earned run average in that time while showing an ability to miss bats (25% strikeout rate) but also some troubles with walks (11%) and home runs (1.25 HR/9).
Though he doesn’t have much of a big league track record, Davis has been sharp in El Paso this season. The journeyman southpaw has a 3.10 ERA in 29 frames and has been outstanding since a shaky start to the year. Over his past 23 1/3 innings, Davis boasts a 1.93 ERA with 32 punchouts and 13 walks. That’s still too many free passes, of course. It’s perhaps worth noting that four of those walks were intentional, but that’s offset by the fact that he’s also plunked four hitters along the way.
Davis’ effectively wild tenure with the Padres’ Triple-A club marks a stark turnaround from a disastrous Triple-A run with the Astros a year ago, when he walked 34 batters and allowed 32 runs in just 25 1/3 innings. Even with that career-worst performance skewing his track record, Davis sports a 4.19 ERA, 29% strikeout rate and 13.6% walk rate in parts of five Triple-A campaigns.
If Davis can carry this season’s success over to the majors and carve out a longer-term spot on the roster, he’d be controllable for three seasons beyond the current campaign, though he has quite a ways to go before that’s a real consideration. The left-hander is out of minor league options, so he’ll have to stick on the roster or else be designated for assignment before he can be sent back down to the minors. Even if he were to clear waivers in such a scenario, he’d have the right to reject a minor league assignment in favor of free agency by virtue of the fact that he’s been outrighted previously in his career.
Padres Make Four Roster Moves
The Padres made four pitching moves today, including the activation of left-hander Tom Cosgrove from the 15-day injured list. San Diego also called up right-hander Pedro Avila from Triple-A, while optioning southpaw Ray Kerr to Triple-A and placing righty Drew Carlton the 15-day IL due to right elbow inflammation.
Carlton signed a minor league contract during the offseason, and was promoted to San Diego’s active roster in the middle of May. Pitching mostly in multi-inning relief situations, Carlton has a 4.35 ERA, 21.2% strikeout rate, and 7.1% walk rate over 20 2/3 frames. That ERA took a hit in yesterday’s game, as Carlton allowed three runs (two earned) in two-thirds of an inning, including a walkoff homer from the Reds’ Spencer Steer. It isn’t known whether Carlton’s elbow issue developed during the game, or if he was trying to pitch through some soreness.
Cosgrove returns from the IL after missing only the minimum 15 days with a strained left hamstring. A 12th-round pick for the Padres in the 2017 draft, the 27-year-old made his MLB debut this season and has made a very solid impression in his first 17 innings in the Show. Cosgrove has a tiny 0.53 ERA and 3.4% walk rate, as well as a solid 25.9% strikeout rate. His SIERA is naturally higher (3.00), as Cosgrove has a perfect 100% strand rate and he has benefited from a .158 BABIP. Still, it’s not a bad showing at all for a pitcher who wasn’t really on the radar for a call-up heading into 2023, but Cosgrove has pitched well enough to retain his spot in the Padres’ bullpen.
