Dodgers reliever Javy Guerra had right shoulder surgery on Friday.
The team said the arthroscopic procedure on his pitching shoulder cleaned up bursitis and a joint at the top of the shoulder. Guerra will start throwing in six weeks and is expected to be ready by spring training.
Guerra had right knee surgery on June 5 to repair torn cartilage after being hit in the face by a line drive. He also was sidelined with a strained oblique muscle for part of the season.
The right-hander was 2-3 with a 2.60 ERA in 45 games this season, finishing with eight saves in 13 chances. As a rookie in 2011, Guerra had a 2.31 ERA and 21 saves.
