"[Mullee] had the thoracic outlet syndrome test; that was clean," Girardi said. "That was our concern, sometimes when you have that funny feeling in your hand. He saw [the Padres'] orthopedic doctor; he didn't do any more tests with him, but the exam was fine."
Mullee was visited at the mound by Girardi and a trainer after he appeared to shake his right arm. He was making the third appearance of his big league career, having debuted on May 16 at Arizona, and was relieved by Richard Bleier.
"My fingers were like sausages. I couldn't feel the ball," Mullee said.
Mullee, 28, said his shoulder and elbow felt normal, which he considered encouraging. This was his second stint with the big league club this season, having been recalled from Triple-A on Tuesday.
