The Chicago White Sox acquire starting pitcher Luis Castillo from the Seattle Mariners in a multi-player trade made ahead of the MLB trade deadline, according to multiple outlets. The Athletic reports that the deal sends Castillo to Chicago after five seasons as a starter in Seattle, while Seattle receives three players in return. Other reports describe the transaction as involving four players total with the Mariners, and a separate outlet frames it as a reliever and a catching prospect plus salary relief for Seattle.
Several sources say Chicago is adding Castillo to strengthen its starting rotation as it pushes for the American League Central title. Yahoo Sports and other outlets note that the White Sox are leading the AL Central and are one season removed from a 102-loss campaign. One Yahoo Sports story emphasizes that the move brings Chicago an experienced, controllable starter without requiring the team to sacrifice top prospects.
Overall, outlets agree on the core elements: Castillo moves from Seattle to Chicago, the Mariners receive multiple players and salary relief, and the trade is intended to help the White Sox’s current contention run.
