Dodgers reliever Blake Treinen likely finished for 2026 season after suffering shoulder injury while warming up

The Los Angeles Dodgers captured their 99th victory by defeating the San Francisco Giants 4-3, though the triumph was overshadowed by a significant roster loss. Relief pitcher Blake Treinen experienced a sudden shoulder flare-up while preparing to enter the contest during the seventh frame, preventing him from taking the mound and requiring teammate Brock Stewart to step in instead.

Dodgers skipper Dave Roberts indicated that the veteran right-hander is anticipated to miss the remainder of the 2026 campaign pending imaging examinations.

Treinen, 38, recently returned to active duty following a 10-week absence that forced him to sit out 62 games due to right elbow inflammation. Over his seven relief outings since being activated, he surrendered three runs and eight hits alongside six strikeouts across six and two-thirds innings, posting a 4.05 ERA.

The reliever previously underwent major labrum and rotator cuff surgery following a 2022 shoulder issue, which sidelined him for the entire 2023 season, though it remains unconfirmed if his latest setback is related to those prior medical concerns.
