Janssen on the mend from shoulder surgery

Blue Jays right-hander Casey Janssen underwent successful surgery on his right shoulder to repair lingering AC joint soreness earlier this month.

The 31-year-old reliever had the small portion of the end of his clavicle shaved down to relieve the discomfort in his throwing arm and is expected to be ready for Spring Training, according to a team press release.

The surgery was performed by Dr. Neal ElAttrache in Los Angeles on Nov. 16.

In six seasons -- all with the Blue Jays -- Janssen has appeared in 283 games (22 starts) and has gone 22-20 with a 3.60 ERA. In 2012, he appeared in 62 games, going 1-1 with a 2.54 ERA and averaging 9.5 strikeouts per nine innings.
