The Rangers also announced that pitcher Wilmer Font underwent arthroscopic surgery to remove a bone spur in his right elbow. Font, who pitched in five games for the Rangers in 2012-13, is expected to be ready for Spring Training 2015.
The Rangers are also shutting down right-hander Akeem Bostick because of a groin injury. He was their second-round Draft pick from West Florence High (S.C.) last year. Bostick was 5-6 with a 5.17 ERA in 21 games at Class A Hickory.
In other Minor League pitching developments, the Rangers are serious about taking a hard look at Lisalverto Bonilla as a starter. Bonilla, who was acquired from the Phillies in 2013 in the Michael Young trade, has been a reliever for most of his career. But he has made four starts at Round Rock and has a 3.37 ERA in those games.
"He has three above-average pitches," farm director Mike Daly said. "We have a lot of right-handed relievers. We have a need for a starter and he has been interesting."
