Scouting Report
Updated May 19, 2026
Sonny Gray, 36-year-old veteran right-handed pitcher for the Boston Red Sox, was placed on the 15-day injured list with a right hamstring strain after leaving his April 20 start against Detroit in the third inning. Gray has since progressed through his rehab, throwing successful bullpen sessions and a simulated game. He was reinstated from the IL and returned to the rotation to start Wednesday against Detroit. Post-return performance shows Gray posting a 4-1 record with a 3.18 ERA over 34 innings with a 21:8 K:BB ratio, leading the Red Sox pitching surge despite some advanced metric concerns about sustainability. The Red Sox are utilizing a six-man rotation with Gray as a key component of their pitching staff overhaul under interim manager Chad Tracy.
