Denoyer underwent Tommy John surgery this week, Roch Kubatko of MASNSports.com reports.
Denoyer will be sidelined for the next year or more and seems likely to miss the entire 2024 season. The 25-year-old right-hander struggled to a 5.61 ERA, 1.71 WHIP and 63:38 K:BB in 51.1 innings this summer with Triple-A Norfolk.
