Colin Balester has elected free agency. The 26-year-old right-hander was acquired by the Tigers last offseason in exchange for Ryan Perry, but struggled to the tune of a 6.50 ERA, 1.39 WHIP and 12/11 K/BB ratio over 18 innings before being banished to Triple-A Toledo for the remainder of the season. He shouldn't have a problem securing a spring training invite on the open market.
