The surgery was performed by team orthopedist Dr. Neal ElAttrache and involved cleaning up bursitis in the AC joint. Guerra will begin a throwing program in six weeks and should be ready for spring training if all goes well.
Guerra posted a 2.60 ERA and a 37/23 K/BB ratio over 45 innings this season while going 8-for-13 in save chances. The 27-year-old right-hander began the season as the Dodgers’ closer, but lost the job to Kenley Jansen in May before requiring knee surgery a month later. He made it back in July, but was demoted in August and suffered a season-ending oblique injury after returning as a September call-up. He’ll hope for better luck on the health front in 2013.
