Scouting Report
Updated May 20, 2026
Justin Martinez, 24-year-old Arizona Diamondbacks closer, underwent Tommy John surgery following an elbow injury sustained on June 9, 2025. He recently completed his first bullpen session post-surgery and demonstrated encouraging velocity, with his fastball sitting in the upper-90s and reaching 99 MPH. Expected return is late August 2026. This represents a positive step in his recovery trajectory, though he remains several months away from game action.
Strengths
- + Fastball velocity already in upper-90s on first bullpen session
- + Velocity reaching 99 MPH demonstrates arm strength recovery
- + Young age (24) suggests good recovery potential
- + Successful completion of first bullpen session post-Tommy John
- + Expected return timeline of late August 2026 is reasonable for this type of surgery
Weaknesses
- - Tommy John surgery requires lengthy rehabilitation period
- - Still months away from return to competition
- - Will require numerous additional bullpen sessions before game action
- - Extended absence from June 2025 through August 2026 represents significant time away
Injury Status: IL-60
