The Rangers opted for Rosales because they had Alberto to take over as their utility infielder.
"We needed a roster spot for Derek Holland," Rangers manager Jeff Banister said. "It was not a move we looked at and said it was an easy move. It was a challenging move. We like Adam and the consistency he brings. Not everybody can sit on the bench and do what he is capable of doing. He gives you a solid professional effort on the field.
"Without playing consistently, that's tough to do and be willing to do that. Plus, Adam is capable of playing all over the field.
