Cubs Acquire Tom Cosgrove, DFA Caleb Kilian

The Chicago Cubs have traded for left-handed reliever Tom Cosgrove from the San Diego Padres in exchange for cash considerations and optioned him to Triple-A Iowa. To make room for Cosgrove on their 40-man roster, the Cubs designated right-handed pitcher Caleb Kilian for assignment, marking a potential end to his time with the team. Cosgrove, who had a strong 2023 season with a 1.75 ERA, has struggled recently, posting an 11.66 ERA in 2024 and a 7.36 ERA in his current stint at Triple-A. Kilian has faced challenges as well, with a 9.22 ERA in his major league appearances since his debut in 2022. This trade is seen as a reclamation project for Cosgrove as the Cubs look to bolster their bullpen depth. The Cubs' management has expressed optimism about the potential for both players to benefit from a change of scenery.
