Tom Cosgrove - MLB News, Rumors, & Updates

Contract selected The Nationals selected Cosgrove's contract from Triple-A Rochester on Friday, Spencer Nusbaum of The Athletic reports.

Impact Cosgrove was just acquired via trade from the Astros last week and is now joining up with the big club. The lefty reliever has logged a 4.15 ERA and 32:22 K:BB across 30.1 innings of work at the Triple-A level this season.

Shipped to Nationals The Astros traded Cosgrove to the Nationals on Friday in exchange for cash, Brian McTaggart of MLB.com reports.

Impact Cosgrove has spent the entire season with Houston's Triple-A affiliate, turning in a 4.30 ERA and 1.44 WHIP to go with a 29:21 K:BB through 29.1 innings. He didn't own a spot on the 40-man roster with the Astros, so he'll slot in as bullpen depth at Triple-A Rochester to begin his tenure with the Nats.

Fails to win Opening Day spot The Astros reassigned Cosgrove to minor-league camp Sunday, Brian McTaggart of MLB.com reports.

Impact Cosgrove is expected to serve as organizational bullpen depth at Triple-A Sugar Land to begin the season after he was unable to secure a spot in the Astros' Opening Day bullpen. The 29-year-old lefty joined Houston on a minor-league deal over the winter after he spent time in the Padres and Cubs organizations in 2025 and made just two relief appearances at the big-league level.

Signs with Astros Cosgrove signed a minor-league deal with the Astros on Thursday, which includes an invitation to spring training, Jon Heyman of the New York Post reports.

Impact Cosgrove has pitched primarily at Triple-A for the last two seasons, working a total of 18.2 innings in the majors. He'll have the chance to battle for a roster spot during spring training.

JANUARY 30 • ROTOWIRE

Remains in organization The Cubs outrighted Cosgrove to Triple-A Iowa on Wednesday.

Impact He's no longer on the 40-man roster, but Cosgrove will remain in the organization after passing through waivers unclaimed. The lefty reliever has spent most of 2025 at Iowa, holding a 4.71 ERA, 1.60 WHIP and 51:25 K:BB over 42 innings.

SEPTEMBER 4, 2025 • ROTOWIRE

Pushed off 40-man roster The Cubs designated Cosgrove for assignment Sunday.

Impact Cosgrove will give up his spot on the 40-man roster to right-hander Aaron Civale, whom the Cubs claimed off waivers from the White Sox on Sunday. Before being optioned to Triple-A Iowa on Aug. 19, Cosgrove made two relief appearances for the Cubs this season, giving up one earned run on three hits and one walk over four innings. His results over a larger sample of 42 innings at Iowa were far less impressive (4.71 ERA, 1.60 WHIP, 51:25 K:BB), however, and the 29-year-old lefty could go unclaimed off waivers as a result.

AUGUST 31, 2025 • ROTOWIRE

Returns to Triple-A The Cubs optioned Cosgrove to Triple-A Iowa on Tuesday.

Impact The left-hander was called up ahead of Game 1 of Tuesday's doubleheader and will return to the minors after not appearing in the matinee. Cosgrove has made just two appearances in the majors this season and has a 4.66 ERA across 38.2 relief innings at Triple-A.

Joins big club for doubleheader The Cubs recalled Cosgrove from Triple-A Iowa on Tuesday, Maddie Lee of the Chicago Sun-Times reports.

Impact Cosgrove will join the Cubs ahead of Tuesday's doubleheader with the Brewers, though it's unclear if he or another player will be sent back to Iowa once the twin bill concludes and Chicago needs to reduce its active roster to 26 men. The 29-year-old southpaw reliever has made just two appearances in the majors this season but has seen ample usage for Iowa, logging a 4.66 ERA and 1.65 WHIP while striking out 47 batters across 38.2 innings over 33 outings.

AUGUST 19, 2025 • ROTOWIRE

Sent back to minors The Cubs optioned Cosgrove to Triple-A Iowa on Saturday, Taylor McGregor of Marquee Sports Network reports.

Impact Cosgrove was brought up from the minors Friday to replace Caleb Thielbar (paternity) but will now head back to Iowa to clear space on the active roster for Cade Horton. Cosgrove has given up just one run in four innings with the Cubs this season and is a candidate to return to Chicago later in the year whenever the big club needs a fresh bullpen arm.

Recalled by Cubs The Cubs recalled Cosgrove from Triple-A Iowa on Sunday.

Impact Cosgrove started the season with the Padres but was traded to the Cubs on April 10. He hasn't allowed a run over four innings in Triple-A while logging seven strikeouts, and he'll move to the majors to provide left-handed depth out of the Cubs' bullpen. Ethan Roberts was optioned to Iowa in a corresponding move.

Impact Cosgrove was pushed off the 40-man roster to make room for right-hander Logan Gillaspie, who had his contract selected from Triple-A El Paso prior to Sunday's game against the Cubs. After turning in a 11.66 ERA and 1.98 WHIP over 14.2 innings at the big-league level in 2024, Cosgrove didn't make much of a claim for a spot in the Padres' Opening Day bullpen this spring and struggled over his first four relief outings with El Paso, giving up three earned runs on four hits and four walks over 3.2 innings.

Optioned to Triple-A The Padres optioned Cosgrove to Triple-A El Paso on Thursday.

Impact Cosgrove never quite got his feet underneath him in the majors last season, turning in an 11.66 ERA and 1.98 WHIP across 14.2 regular-season innings. His struggles followed him into spring training, where he allowed seven runs in just 5.1 frames, so the Friars will keep him in the minor leagues for now.
