White Sox land Castillo in four-player deal to stabilize rotation
The Chicago White Sox acquired Luis Castillo from the Seattle Mariners in a four-player trade for Nolan Jones, Seranthony Dominguez, and Boston Smith, taking on Castillo’s $22.75 million contract for the next two years with a 2028 option. Castillo, 33, has posted a 5.06 ERA this season but is a proven mid-rotation arm who could help the White Sox in their playoff push. Erick Fedde will move to the bullpen to accommodate the addition, while Seattle may contemplate further rotation moves as the deadline approaches.
