Sonny Gray was successfully traded from the St. Louis Cardinals to the Boston Red Sox on Tuesday, despite the guaranteed $40 million Gray is set to make by the end of 2026.

 Ty and Colby discuss that, then weigh the pros and cons of trading not just Castillo, but each of Seattle's five main starting pitchers.
