The Chicago Cubs have acquired left-handed pitcher Tom Cosgrove from the San Diego Padres on Thursday. In a corresponding move, the Cubs designated right-handed pitcher Caleb Kilian for assignment. Cosgrove was designated for assignment by San Diego over the weekend and will look to turn the corner with the Cubs. Through the early part of the Triple-A regular season, Cosgrove logged three 2/3 innings with El Paso. Across this brief stint, he allowed four runs (three earned) and held a 4:2 BB:K. Last season, Cosgrove logged 14 2/3 innings in the majors and struggled there as well, holding a high 11.66 ERA. However, during the 2023 campaign, the southpaw posted a stellar 1.75 ERA with a 0.97 WHIP across 51 1/3 innings. He will likely report to Triple-A Iowa.

San Diego Padres reliever Tom Cosgrove (hamstring) was activated from the 15-day injured list on Saturday. The left-hander has been on the shelf since mid-June because of a strained left hamstring. But he made good progress while on the shelf, so his activation isn't surprising. Cosgrove is 1-0 in 16 appearances this season. He also has a 0.53 ERA and 15 strikeouts. However, the 27-year-old isn't productive in the categories that matter to fantasy managers, so the latest update won't mean much.

San Diego Padres left-hander Tom Cosgrove (hamstring) is ready to face hitters for a second time on Thursday, according to MLB.com. The 27-year-old has been on the injured list since June 16 after straining his left hamstring, but manager Bob Melvin told reporters that he could be activated before Friday's game against the Cincinnati Reds. Cosgrove has been a bright spot in the club's bullpen, pitching to a 0.53 ERA, 0.53 WHIP, and 25.9% strikeout rate across 17 innings, but has yet to earn a save or a hold. Until he begins pitching in the later innings, fantasy managers should keep the rookie on the waiver wire.
