Winn is scheduled to undergo a season-ending ulnar nerve transposition procedure Monday on his right elbow, Shayna Rubin of the San Francisco Chronicle reports.
Winn was initially placed on the 15-day injured list June 22 due to a nerve issue in his right elbow. He began his rehab program by throwing bullpen sessions in early July, but he was shut down from throwing Monday after experiencing additional discomfort and has now been recommended for surgery. Winn will shift his focus to getting healthy for spring training, but he'll finish the 2024 campaign with a 3-8 record, 7.16 ERA, 1.37 WHIP and 48:20 K:BB across 55.1 innings.
