Cubs finalize Tom Cosgrove trade, designate Caleb Kilian

The Chicago Cubs have made a significant trade, acquiring left-handed pitcher Tom Cosgrove from the San Diego Padres while designating Caleb Kilian for assignment. This move represents the culmination of the 2021 trade that sent Kris Bryant to the Giants, as Kilian was one of the major prospects received in that deal, alongside Alexander Canario. Kilian struggled in his major league appearances, finishing with a 9.22 ERA over eight games, while Cosgrove comes off a challenging 2024 season but previously showcased potential with a 1.75 ERA in 2023. The Cubs are looking to bolster their pitching staff amid injuries and uncertainties, particularly with Justin Steele now on the injured list. Cosgrove has been optioned to Triple-A Iowa, and his performance will be monitored closely as the Cubs aim to remain competitive in the NL Central. The departure of Kilian and Canario highlights the ongoing fallout from the Cubs' past trade decisions as they navigate roster changes.
