Reliever Blake Treinen has been placed on the injured list with right elbow inflammation, the Dodgers announced before their game against the Baltimore Orioles on Saturday.
Treinen pitched a perfect ninth inning against the Orioles the previous night, setting the stage for a comeback in the bottom half of the inning. The Dodgers scored three runs in a walk-off, 6-5 victory.
The 37-year-old right-hander has pitched in 29 games this season and is 4-1 with a 3.52 earned-run average.
Treinen was replaced on the active roster by right-hander Chayce McDermott, who was recalled from triple-A Oklahoma City. This will mark McDermott’s second stint with the Dodgers. He pitched a scoreless inning against the Angels on April 27.
McDermott, 27, has pitched in six major league games in his career, the other five with the Orioles from 2024 to 2025.
