Scouting Report: Juan Parra
Chicago Cubs | SS
Overall
Summary
Juan Valera, 19-year-old Red Sox RHP prospect, underwent Tommy John surgery on May 6, 2026, after suffering an elbow injury during his third start of the season for High-A Greenville. Valera was off to an exceptional start, striking out 17 batters in 9.1 innings with a 1.93 ERA before the injury. He had recently made Baseball America's Top 100 prospects list. This marks his second consecutive season with an elbow injury (missed 3 months in 2025). Recovery typically takes 12-14 months, sidelining him through most of 2027. MLB.com scouts have suggested a potential future closer role due to durability concerns as a starter.
