The Texas Rangers have recalled righthanded reliever Roman Mendez from AAA Round Rock. To make room for Mendez on the active roster, the Rangers have designated lefthanded reliever Ross Detwiler for assignment.
Detwiler was acquired by the Rangers from the Washington Nationals in the offseason, in exchange for Chris Bostick and Abel de los Santos, to be the team's fifth starter. The injuries to Yu Darvish and Derek Holland, however, turned Detwiler into the #3 starter, and whether the #3 starter or the #5 starter, he wasn't up to the task. Detwiler landed on the d.l. in May, and upon returning, he moved into the pen. A free agent after this season, Detwiler never gained manager Jeff Banister's trust in a relief role, and with a 40 man roster spot needed for when Martin Perez gets activated next week, Detwiler ended up being a roster casualty.
Mendez started the year on the Opening Day roster, but has struggled to establish himself as a consistent major league relief arm. He has a 2.57 ERA in 14 IP in Round Rock this year, and a 5.40 ERA in 11.2 IP in Texas. Mendez is on his final option, and this will give the Rangers a chance to get a closer look at him before they have to make a decision on carrying him on the 40 man this offseason.
