Czech Lukas Rosol, who stunned two-time champion Rafael Nadal at Wimbledon, is unsure why the Spaniard bumped into him during a changeover early in the third set of his five-set victory. Nadal wouldn't speak to the issue, but it appeared he was upset that Rosol was bouncing up and down while he was serving.

"I was surprised that he can do it on the Centre Court Wimbledon," Rosol said. "It's like something wrong. But I didn't expect it also. Was his choice. He did it. ... I just stop. I thought that he wants to let me go first, but then he start to walk fast. I stop because I don't want to hit me. He hit me, and then three times he apologize. And I say, Okay, okay, okay. It was okay."
