The surgery stems from an injury Ross suffered early in the season, when he picked up his first major league hit on April 17. That caused a partial dislocation of his left shoulder, putting him on the DL for a three-week stint. Because the injury was not to his throwing arm, Ross was able to continue pitching through 2013.
The Padres acquired Ross from the Athletics in an off-season trade last year. The deal worked out better than San Diego could have imagined as Ross excelled with a 3.17 ERA over 35 appearances, 16 of which were starts. He began the year in the rotation, but came out of the bullpen after returning from the disabled list.
Ross rejoined the starting rotation on July 23 and became one of the best pitchers on the team, posting a 2.93 ERA over the remainder of the season and holding opposing hitters to a 580 OPS.
He is expected to fully recover from the surgery in time for spring training.
