Dodgers P Guerra has surgery

The Los Angeles Dodgers announced reliever Javy Guerra underwent arthroscopic surgery on his right shoulder Friday.

The team announced the procedure was to clean up bursitis and the A-C joint.

Guerra, who didn't pitch after Sept. 2 due to a left oblique muscle strain, compiled a 2-3 mark with eight saves and a 2.60 ERA in 45 games in 2012. He didn't allow a run in his final 10 appearances, a span of 12 1/3 innings.
