Pittsburgh Pirates Pitcher Mitch Keller Out for Season with Arm Injury
Pittsburgh Pirates pitcher Mitch Keller's season has ended due to a right arm teres major muscle injury, placing him on the 60-day injured list.

Pittsburgh, PA, August 8, 2026 —
Mitch Keller, a prominent pitcher for the Pittsburgh Pirates, will not pitch for the remainder of the season. The team announced that Keller has been placed on the 60-day injured list due to a diagnosed injury to his right arm’s teres major muscle.
The teres major is a muscle located in the shoulder region, and its injury can significantly impact a pitcher’s ability to throw effectively. The timeline for Keller’s recovery and return to play will be determined following further evaluation and rehabilitation, but his placement on the 60-day injured list effectively ends his current season.
The specific details regarding when the injury occurred or how it happened were not immediately available. The Pittsburgh Pirates have not provided further information on the extent of the injury or the projected recovery process beyond placing him on the injured list.
Keller’s absence represents a significant loss for the Pirates’ pitching rotation. His performance statistics and contributions throughout the season have been a key aspect of the team’s strategy. The team will now need to adjust its pitching plans to account for his unavailability for the remainder of the games.
Further updates on Keller’s condition and the team’s subsequent roster adjustments are expected as the season progresses.
