Rafael Nadal grimaces in pain during post-match interview

NEW YORK

Nadal easily advanced to the fourth round of the U.S. Open on Sunday. But the drama came during his post-match press conference.

Nadal was answering questions in Spanish, when he suddenly started grimacing in pain. The defending champion tilted his head back, his face twisted in agony.

He motioned for help as he slid down in his chair. Fortunately he was just suffering from leg cramps.
