Dirks was released by the Blue Jays on Thursday, Tony Paul of the Detroit News reports. Dirks was brought on board in January, but he continues to battle a back injury, which has prevented him from seeing the field thus far in 2015. After appearing in 131 games for the Tigers in 2013, Dirks played in just 14 minor league contests in 2014. He's only 29 years old, but he'll need to prove he's capable of staying healthy before returning to the majors becomes a real possibility.
