Scouting Report
Updated May 19, 2026
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. As of May 2026, he has begun his recovery progression, completing his first bullpen session at Salt River Fields. His fastball velocity was encouraging, sitting in the 96-99 mph range with peaks at 99 mph. Manager Torey Lovullo described the session as "electric." Martinez still requires approximately 15 bullpen sessions before advancing further in his recovery timeline, with an expected return to the bullpen targeted for late August 2026. Prior to injury, Martinez had saved 13 games in 2024-25 with a 2.76 ERA and triple-digit fastball velocity, along with a nasty secondary arsenal featuring a splitter and slider. He signed a contract extension in spring training 2025 before his injury.
