He offered the thumbs-up afterward.

Hamels remains on target to pitch Wednesday afternoon against the Yankees at Yankee Stadium. He missed Friday's start against the Cardinals because of tightness in his right hamstring. Hamels said Friday he never considered the injury serious.

Hamels' health is important with the July 31 Trade Deadline approaching. The Phillies intend to trade him to speed up their rebuilding efforts.
