Zach Eflin underwent season-ending Tommy John surgery on Wednesday.

The procedure, performed by Dr. Keith Meister, will sideline Eflin until at least the early stages of the 2027 season. The 32-year-old veteran suffered the injury during his season debut last week, and it marks the first reconstructive surgery of his career. His absence is a significant hit to Baltimore’s rotation depth and likely means that one of Dean Kremer, Cade Povich or Brandon Young will have to step into a more prominent role this season.
