Scouting Report
Updated May 19, 2026
Justin Martinez, 24-year-old Arizona Diamondbacks closer, underwent Tommy John surgery in June 2025 after suffering an elbow injury. He has begun his recovery process with his first bullpen session in May 2026, where he demonstrated encouraging velocity (96-99 mph fastball). Manager Torey Lovullo described the session as "electric." Martinez requires 15 total bullpen sessions before progressing to a minor-league rehab assignment, with a potential return targeted for late August 2026. The young right-hander previously saved 13 games in 2024-25 with a 2.76 ERA and triple-digit fastball.
