Casey Janssen

Casey Janssen is an American reliever on the Toronto Blue Jays.

Casey Janssen broke into the league with Toronto as a starter in 2006. Although he pitched effectively, Janssen moved to the bullpen and developed into one of the best setup men in the league. He continued to pitch well in 2007, but was injured in the offseason, and had surgery that kept him out of the entire 2008 campaign.
