Scouting Report: Jon Gray

Summary

Sonny Gray, a 36-year-old veteran right-handed pitcher, was activated from the 15-day injured list on May 6, 2026, after suffering a right hamstring strain on April 21. Gray has made 6 starts for the Boston Red Sox in 2026 with a 4-1 record and 3.18 ERA over 34 innings pitched. However, underlying metrics reveal concerning regression indicators: his Expected ERA (xERA) is 5.16 and FIP is 4.18, significantly higher than his surface ERA. His BABIP is elevated at .285 and LOB% is high at 78.5%, suggesting he has benefited from favorable defensive support and luck. Gray was traded to Boston from St. Louis in the offseason and struggled early (4.30 ERA in first 5 starts) before the injury. He has a K:BB ratio of 21:8 and recently pitched 6 innings against Philadelphia, allowing 1 run on 2 hits with 6 strikeouts. The Red Sox rotation has been depleted with injuries to Garrett Crochet (shoulder) and Ranger Suárez (hamstring).
