EASTBOURNE, England -- Wimbledon champion Petra Kvitova was among the top three women's seeds to fall in the first round of the Eastbourne Championships on Tuesday.
"Regardless of what he had going on, I hit the ball really well," said Roddick, whose last victory came in Miami three months ago. "Last couple of days it's been really good in practice. I don't know why or how or what the process has been, but it's felt pretty good."
Top-seeded Richard Gasquet of France was upset 1-6, 7-6 (5), 7-6 (3) by Australian qualifier Marinko Matosevic, and fifth-seeded Frenchman Julien Benneteau went down 6-3, 2-6, 7-6 (4) to Yen-Hsun Lu of Taiwan.
Kvitova was the first to exit, going down 7-5, 6-4 to Ekaterina Makarova of Russia.
"It was a tough opponent for me for the first round, and I didn't play well," Kvitova said. "She has won here in the past, so I know that she can play well on the grass. For me, this was my first match on grass and I didn't expect too much."
Wozniacki always looked uncomfortable against the big-hitting McHale.
After splitting the first two sets, McHale broke to lead 2-1 in the third. Although she allowed Wozniacki to level at 4-4, the American broke serve again at love and closed out the match on her fourth match point.
The second-seeded Kvitova put on an erratic performance during her first match on grass since lifting the trophy at Wimbledon last year.
"It's not good preparation for Wimbledon, but I have more days for getting ready. I have to work hard now to improve my game," Kvitova said.
Radwanska has enjoyed a spectacular season, winning titles in Dubai, Miami and Brussels, and she believes that may have taken its toll.
"I think I have been playing a lot of matches this year, and I'm kind of like a little bit tired," said Radwanska, who double-faulted on match point. "Of course I was trying everything, but she's really playing good on grass."
