Rangers right-hander Neftali Feliz, who left his start Tuesday after three innings with shoulder stiffness, received treatment Wednesday at the Rangers facility and reported improvement. He will be re-evaluated Thursday.

The Rangers don't view the situation as serious enough to merit an MRI exam at the time. An MRI might reveal changes to the area around the shoulder joint.

This is not a new situation for Feliz. He had shoulder soreness last spring that did not keep him from starting the season as the team's closer. However, it resurfaced in late April, and he missed two weeks.
