Baltimore Orioles pitcher Randy Wolf will undergo Tommy John surgery on his left elbow and miss the entire 2013 season, according to a report by the Baltimore Sun

Wolf, who appeared in five games for the Orioles in 2012, signed with the club at the end of August after being released by the Milwaukee Brewers.

After feeling discomfort in his pitching elbow following a start in Boston on Sept. 22, he was diagnosed with a ligament tear and was shelved for the remainder of the season.

The 36-year-old is expected to have surgery on Oct. 30, forcing him to miss all of the 2013 season.

Over his 14-year career, Wolf has collected a 132-117 record with a 4.20 ERA.
