Scouting Report
Updated May 19, 2026
Juan Valera, Boston Red Sox prospect (ranked 4th-5th in organization), underwent Tommy John surgery in May 2026 after suffering elbow inflammation during his third start of the season at High-A Greenville. The 19-year-old had an impressive start with 17 strikeouts over 9.1 innings and a 1.93 ERA before the injury. Recovery from Tommy John surgery typically requires 12-14 months, meaning he will miss most of the 2027 season. MLB.com scouts have suggested a potential future as a closer due to recurring health issues as a starter.
