Overview

• Luis Castillo, a three-time All-Star with a 3.56 career ERA, is reportedly being pursued by the Cubs, Red Sox, Mets, and Orioles in potential offseason trade discussions.
• The Mariners may be open to trading Castillo, citing his higher salary and their need to address offensive gaps while operating under payroll constraints.
• The Cubs, fresh off acquiring Kyle Tucker, are exploring options to bolster their rotation and could offer infielders like Nico Hoerner or pitching prospects in a deal.
• The Red Sox, despite recently landing ace Garrett Crochet, remain interested in Castillo to further strengthen their rotation for a competitive AL East push.
• Castillo's no-trade clause gives him some control over his next destination, adding complexity to any potential deal.
