Overview
- The club announced the right-hander’s designation for assignment on Thursday, bringing the 40-man roster to 40.
- Players reinstated were Kutter Crawford, Hunter Dobbins, Tanner Houck, Josh Winckowski, Patrick Sandoval, Vaughn Grissom, Marcelo Mayer, Triston Casas, and Guerrero.
- Boston has seven days to trade Guerrero or place him on waivers, which carry a 48-hour claim period.
- Further space will likely be needed this month for Rule 5 protections and offseason additions, with the non-tender deadline set for Nov. 21.
- Guerrero, 25, owns a 2.63 ERA over 27.1 MLB innings, struggled with command in 2025, and missed the second half with a right elbow strain.
