Tigers purchased the contract of RHP Melvin Mercedes from High-A Lakeland.
Mercedes returned from Tommy John surgery this season and compiled a 2.76 ERA and 43/24 K/BB ratio over 65 1/3 innings between Class A and High-A. While he has only averaged 6.4 K/9 over five seasons in pro ball, he throws quite hard and could emerge as a useful pitcher out of the bullpen.
