In 29 starts for Boston, Gray posted a 2.72 ERA, the fifth-lowest among qualified American League starters and the eighth-lowest among qualified starters in baseball. In addition to posting the second-lowest ERA of his career, Gray finished the season tied for the league lead in wins with 18. Gray’s career renaissance was especially important in 2026, as the Red Sox lost 2025 American League Cy Young Award runner-up Garrett Crochet to a left shoulder injury on April 26, which ended his regular season. In Crochet’s absence, Gray and rookie Payton Tolle helped carry the Red Sox pitching staff to the third-lowest team ERA in baseball.
