TORONTO - Toronto Blue Jays reliever Casey Janssen has undergone successful right shoulder surgery and is expected to be ready for spring training.

Janssen had the surgery Friday in Los Angeles to repair lingering joint soreness, the team said.

The 31-year-old right-hander had the small portion of the end of his clavicle shaved down to relieve the discomfort.

Janssen was thrust into the closer role last season after an early season-ending injury to Sergio Santos, and he thrived in the position.

Janssen converted 22 of 25 save opportunities while posting a .195 earned-run average. He had 67 strikeouts compared to just 11 walks over 63 2/3 innings.
