Kim Clijsters, after a lopsided 6-0, 6-1 loss to Nadia Petrova: "I was completely off. Just I think tennis-wise, I didn't feel the ball at all.

"It was weird. I don't know. It was just really like my arms, and like I said, I wasn't hitting the ball. Like everything was too soft.

"On the other hand, she was good. But, you know, I made all the mistakes and she didn't really have to do much. She served really well and was aggressive in the rallies, but that's because I let her play into the courts. Just because I wasn't feeling the ball well. It sucks.

"It's something that you know as an athlete that can happen once in a while... once a year, hopefully not more than that. But, yeah, the question is of course, 'Why?' My coach, my fitness coach, are like, 'How can something like this happen?'"
