The Tigers have designated right-hander Melvin Mercedes for assignment to create roster space for today’s moves, the club announced (via Anthony Fenech of the Detroit Free Press, on Twitter).
Mercedes, 24, was signed as an amateur free agent by Detroit in 2008 and posted a 3.15 ERA, 1.51 K/BB rate and 6.0 K/9 over 297 1/3 minor league innings, all of them out of the bullpen. He got his first taste of the majors in 2014, throwing two perfect innings of relief in one game for the Tigers.
