Right-hander Neftali Feliz coming back from Tommy John surgery tried to warm up during Sunday's game for Triple-A Round Rock but stopped.

He has been shut down for the moment with right triceps tendinitis. The Rangers don't believe it is serious and said it is a common issue for pitchers coming off Tommy John surgery.

Feliz was supposed to pitch an inning Saturday but wasn't able to go. He didn't allow a run in 2/3 innings Thursday for Round Rock but he did load the bases.
