During the 25-minute procedure, Dr. Neal ElAttrache cleaned up bursitis in the A-C joint at the top of Guerra's shoulder, according to the team. Guerra will begin a throwing program in six weeks and be ready for spring training if all goes well.
The Dodgers have had a busy surgery season. Matt Kemp (shoulder), A.J. Ellis (knee), Kenley Jansen (irregular heartbeat) and Guerra have all undergone procedures. Outfielder Carl Crawford also will be coming off elbow surgery he underwent in June. In addition, the Dodgers have questions about the health of pitchers Ted Lilly (shoulder) and Chad Billingsley (elbow).
Guerra, 27, was 2-3 with a 2.60 ERA and eight saves for the Dodgers last year. He was supplanted as closer by Jansen, who was subsequently replaced by Brandon League. The Dodgers signed League to a three-year, $22.5 million contract extension earlier this week.
