According to the Dodgers, Haren underwent the procedure to clean out bursitis in the joint where the collarbone meets the top of the shoulder. Team doctor Neal ElAttrache performed the operation.
Haren went 13-11 with a 4.02 ERA in 32 starts as the fourth starter -- his 10th consecutive season of double-digit wins. He opened the season going 4-0 while the Dodgers dealt with the injury absence of Clayton Kershaw, then finished the season 5-2 while the club dealt with the injury absence of Hyun-Jin Ryu.
The three-time All-Star also went through a mid-season five-game losing streak on his way to finish the year with 186 innings pitched.
