Rest-of-Season Projections
Signed a one-year contract with the Red Sox in March of 2025. Traded to the Rays in November of 2025.
Dealt to Rays
The Rays acquired Guerrero from the Red Sox on Tuesday in exchange for Tristan Gray.
Analysis
Guerrero was outrighted off Boston's 40-man roster last week after passing through waivers unclaimed, but now he's on the move to a new organization. The right-hander holds a 2.63 ERA but a 19:16 K:BB across 27.1 frames covering parts of two major-league seasons. Guerrero has a big arm and the Rays will now be tasked with getting him to throw more strikes, which is something they've had success with as an organization with other hurlers.
