Tigers Designate Donn Roach, Add Joe Mantiply To Roster

The Tigers have announced that they’ve designated righty Donn Roach for assignment. The move clears space on the team’s roster for lefty Joe Mantiply, whose contract the team has selected from Double-A Erie.

The Tigers claimed Roach from the Mariners last month, and he made five starts for Triple-A Toledo. Between Toledo and the Mariners’ affiliate in Tacoma, Roach has posted a 3.86 ERA, 5.4 K/9 and 1.6 BB/9 over 137 2/3 innings at the Triple-A level this season. The 26-year-old has appeared in the big leagues in each of the last three seasons, including in 5 1/3 innings in the Mariners’ bullpen this season.

The 25-year-old Mantiply was a 27th-round draft pick in 2013, but he made quick work of the lower levels of the Tigers’ system and has fared well in the high minors this season, with a 2.73 ERA, 10.5 K/9 and 1.8 BB/9 in 59 1/3 innings split between Double-A and Triple-A. He likely would have been a potential Rule 5 Draft selection this winter, but his addition to the Tigers’ 40-man roster protects the team from that possibility. He’ll join Justin Wilson, Kyle Ryan and Blaine Hardy as lefties in the Tigers’ bullpen.
