White Sox risk $20 million loss on Luis Castillo's 2027 performance

Summary

The Chicago White Sox acquired pitcher Luis Castillo from the Seattle Mariners at the trade deadline. The White Sox assumed Castillo's full contract, valued at $20 million for the 2027 season, which now risks becoming a financial misstep. During his nine appearances with Chicago, Castillo posted a dismal 8.42 ERA and a -0.9 bWAR, following a lackluster stint with the Mariners. Concerns grow as the White Sox seek solutions for Castillo to rebound next season.
