Scouting Report
Updated May 20, 2026
Juan Valera, 19-year-old Boston Red Sox RHP prospect (ranked #4 in system), underwent Tommy John surgery on May 2026 after exiting his third start with right elbow inflammation. He was off to an exceptional start with 17 strikeouts in 9.1 innings (1.93 ERA, 0.125 BAA) before the injury. This marks the second consecutive season with elbow issues (missed 3 months in 2025). Recovery timeline is 12-18 months, likely sidelining him through most of 2027. MLB.com scouts suggested a potential future closer role given his elite fastball (96-98 mph, touches 101.7 mph) and upper-80s slider with two-plane depth.
