Is Warner Madrigal the newest bullpen piece?

The Rangers reliever makes the most since to give the team a fresh arm for Thursday's series opener against Seattle. The Rangers can send Guillermo Moscoso back down and call up the right-hander. He was removed from the Oklahoma City bullpen Wednesday and Texas manager Ron Washington said the team would discuss a roster move. Only Jason Grilli, Dustin Nippert and C.J. Wilson weren't used Wednesday night and Nippert wasn't available.
