Wisler was released by the Tigers on Saturday, Evan Woodbery of MLive.com reports.
Wisler underwhelmed with a 4.40 ERA and 1.57 WHIP in 39 appearances at Triple-A Toledo and failed to crack Detroit's big-league roster. The right-hander had some buzz when he broke into the majors, but he's now pitched in parts of eight big-league seasons and may very well have exhausted his opportunities in the majors.
