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.

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.

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.

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.

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.

Ethan Roberts was optioned to Iowa in a corresponding move.

Gets new opportunity Cosgrove was traded from the Padres to the Cubs on Thursday, Andy Martinez of Marquee Sports Network reports.

Impact Cosgrove was designated for assignment by the Padres on Sunday but will now offer the Cubs bullpen depth. He has pitched primarily in the minors throughout his career, though he has maintained a 3.95 ERA and 1.20 WHIP across 66 big-league frames.

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

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.

MARCH 13, 2025 • ROTOWIRE

Returns to El Paso The Padres optioned Cosgrove to Triple-A El Paso on Saturday.

Impact Cosgrove came up from the minors Wednesday as a roster replacement for Martin Perez (paternity), and he'll head back to Triple-A now that Perez has returned. The 28-year-old Cosgrove didn't appear in a game during his three-day stint in the big leagues.

Returns to El Paso The Padres optioned Cosgrove to Triple-A El Paso on Saturday.

Impact Cosgrove came up from the minors Wednesday as a roster replacement for Martin Perez (paternity), and he'll now head back to Triple-A now that Perez has returned. The 28-year-old Cosgrove didn't appear in a game during his three-day stint in the big leagues.

SEPTEMBER 14, 2024 • ROTOWIRE

Back in majors The Padres recalled Cosgrove from Triple-A El Paso on Wednesday.

Impact Cosgrove has allowed 19 earned runs over just 14.2 innings in the majors this season, but he'll return to San Diego nonetheless to give the Friars a left-handed bullpen arm while fellow southpaw Martin Perez is on paternity leave. The 28-year-old Cosgrove will almost certainly be limited to low-leverage situations while in the big leagues.

SEPTEMBER 11, 2024 • ROTOWIRE

Returns to Triple-A Cosgrove was optioned to Triple-A El Paso on Wednesday.

Impact The left-hander was called up from El Paso on Sunday and will return there without taking the mound for San Diego. Cosgrove has appeared in 18 games for the Padres this season and has a 11.66 ERA, 1.98 WHIP and 15:6 K:BB over 14.2 innings.
