Los Angeles Dodgers reliever Blake Treinen suffers a shoulder injury while warming up in the bullpen during a game against the San Francisco Giants. Multiple outlets report the injury occurs as he is preparing to pitch, prompting immediate adjustments as other pitchers take over bullpen duties.
The Dodgers are expected to place Treinen on the injured list, and several reports say the setback likely ends his run for the postseason. One outlet notes that Treinen is likely finished for the 2026 season, while others frame the prognosis more specifically around missing the playoffs.
The injury arrives after Treinen returns to action earlier this month. Yahoo Sports reports he is activated in early September after missing 62 games with right elbow inflammation. Across coverage, the central details—where the injury happens (bullpen warmups), that it is a shoulder injury, and that an injured-list placement is expected—are consistent, with differences mainly in how long the injury will keep him out.
