Scouting Report: Seth Martinez
Boston Red Sox | RP
Overall
Summary
Justin Martinez, 24-year-old Arizona Diamondbacks closer, underwent Tommy John surgery in June 2025 after suffering an elbow injury. He recently completed his first bullpen session since surgery at Salt River Fields on May 8, 2026, throwing fastballs in the 96-99 mph range with excellent velocity recovery. Manager Torey Lovullo described the session as "electric." Martinez will need to complete approximately 15 bullpen sessions before progressing to a minor-league rehab assignment, with a potential return targeted for late August 2026. Prior to injury, Martinez saved 13 games in 2024-25 with a 2.76 ERA and triple-digit fastball velocity.
