Scouting Report
Updated May 20, 2026
Juan Valera, 19-year-old Red Sox pitching prospect, underwent Tommy John surgery on May 6, 2026, after suffering a right elbow UCL injury during his third start of the season on April 16. Initially diagnosed as elbow inflammation, subsequent MRI imaging revealed the need for surgical reconstruction. Valera was off to an exceptional start, posting a 1.93 ERA with 17 strikeouts in 9.1 innings across three starts before the injury. The surgery typically requires 12-14 months recovery, likely sidelining him for most of the 2027 season.
