He could be used as a reliever instead of a starter. McCarthy was 1-0 with a 2.51 ERA in four starts with Oklahoma City before he went down, but assistant general manager Thad Levine said that the Rangers are likely to discuss the possibility of moving him to the Oklahoma City bullpen.
"We want to give ourselves as much flexibility as we can to see if it gives him an opportunity to help us at the Major League level," Levine said. "One of the strengths of the organization is our Major League-ready pitching depth, and he is part of our depth."
McCarthy has made 56 starts and 54 relief appearances at the Major League level. But he has made 44 starts and only one relief appearance for the Rangers.
