Scouting Report: Adrian Martinez
Chicago Cubs | RP
Overall
Summary
Justin Martinez, 24-year-old Arizona Diamondbacks closer, underwent Tommy John surgery on his right elbow in June 2025 after suffering an injury on June 9. He has recently completed his first bullpen session since surgery (May 8-9, 2026), throwing at 96-99 mph with his fastball, described as "electric" by manager Torey Lovullo. Martinez previously saved 13 games in 2024-25 with a 2.76 ERA and triple-digit fastball. He is expected to need 15 total bullpen sessions before progressing to a minor-league rehab assignment, with a potential return targeted for late August 2026. This represents significant progress in his recovery journey.
