Sharapova will next face No. 20 seed Shuai Peng, who beat Melinda Czink 6-2, 7-6(5). Wozniacki was a mirror-opposite of Sharapova in her 6-3, 6-2 win over No. 27 seed Jarmila Gajdosova, making only six unforced errors.

“I’ve been playing very well my two matches here and hopefully I can keep it up,” Wozniacki said. “I’m serving well, I’m moving well, and I’m moving the ball around well. I won the junior title here in 2006 and Eastbourne [WTA event] two years ago. Hardcourt is my best surface, but grass is good for me as well.”

The favorites Rafael Nadal, Roger Federer and Novak Djokovic looked dominant early at Wimbledon.

“It was a long time ago, but he beat me,” Nadal said. “So that’s what happened. Gilles is a very dangerous player, especially on this surface. So it will be a very tough match for me. I don’t know what is my best form, I try my best every day. I need a few adjustments.”

John Isner on playing Nicolas Mahut again: “It’s going to be pretty nuts. I couldn’t believe it. I joked with him earlier in the week, last week, and said, ‘Watch us play each other.’ And he said, ‘No, there’s no way. That’s not even funny.’”

Did I mention world No. 1 Caroline Wozniacki is the No. 1 seed? Talk about under the radar.

Schiavone beat France’s own Marion Bartoli 6-3, 6-3, mixing up her game to confound the two-hander who committed 18 unforced errors to 11 winners.

“I am through. I’m in the semifinals, so that’s the thing,” Nadal told reporters. “I have to be playing better and better every day if I want to have chances to win the final and that’s what I’m going to try.”

“I started too slow, absolutely too slow,” Schiavone said. “The key was to hit three, four, five, six, seven balls, but I couldn’t arrive at three, four. That was the way to win — if I went to the net in one shot, there was no way to win. From 4-1 down I played two really good games then she went a little bit down.”

Li will next face No. 4 seed Victoria Azarenka, who advanced easily 6-2, 6-3 over unseeded Russian Ekaterina Makarova.
