Top seed stunned; former champions through

It didn't seem like the top seed recovered from yesterday's match, as Ana Ivanovic was stunned by Chinese Zheng Jie in straight sets, 61 64.

Ivanovic followed Sharapova into the sidelines as she made an early exit at Wimbledon. Her last match was with Nathalie Dechy, who she nearly lost to, surviving two match points and winning the third set 10-8. Ana's game was even worse at the third round match, when she smacked errors in every direction, especially off her pinpoint forehand.

"I felt it was a tough match because she has the big serve and big forehand; but I just kept telling myself I needed to be 100% because she's the better player," Zheng said. "I tried to put the ball to her backhand more. I also felt she was serving so-so today, so I could go after my returns more."

I'm definitely disappointed but I look at it as a learning experience, and she did play very well today," Ivanovic said. "She's a good player and plays well on grass. She has power and stays very low, so the balls are coming much faster. I had a tough time adjusting to the timing and it was also a little bit windy."

"On grass, everything is happening so fast," Ivanovic said. "You really have to be there from the first point on, and that's something I found hard. She was hitting fast and flat. I didn't have time to get into my game. On clay if you have a slow start it's okay, because you have more time in the points to find your rhythm."

This is Zheng's best result in the Tour, as she is the first Chinese player to beat the reigning World No. 1. Jie had never beaten a Top 10 player, her best win was to No. 11 ranked Anastasia Myskina in the championship match of Stockholm in 2006. It is remarkable, as Zheng missed the first half of the last year's season with a left ankle injury, and needed a wildcard to compete here.

"It's even more exciting because last year I was injured and missed Wimbledon," Zheng added. "I've only been back half a year and I'm playing like this, so it's a nice surprise. I'll just try my best and hope to keep going in the tournament."

Next up for Zheng will be No.15 seed Agnes Szavay, who beat Anabel Medina Garrigues, 76(5) 26 62, to reach the fourth round here for the first time.

Svetlana, Serena determined to win; last year's finalist crushed

Svetlana Kuznetsova and Serena Williams came one step closer to a quarterfinal clash, as No. 4 seed Sveta won to qualifier Barbora Zahlavova Strycova in straight sets, and the sixth seeded American champion ended the run of Wimbledon champion Amelie Mauresmo, also in straight sets, 62 64.

"I was ready to go; she was too, especially in that first set," Williams said on Mauresmo. "I was trying to be aggressive. I've been working on coming into the net in general. I was trying to come to the net because I've been hitting my volleys well. I tightened up a little bit at the end of the first set but was able to relax a bit and close it out, then I won the second set pretty quickly."

For Kuznetsova, her win was a birthday present from herself: the russian, who currently is ranked No. 4, behind Ivanovic, Sharapova, and Jankovic, turned 23 this year.

"It's special. You want always to have a win, otherwise your birthday is a bit bad," Kuznetsova said. "It was hard, because I woke up in the morning and I got so many messages, but I really wanted to focus on my match. I almost switched off all my phones, but then it's nice because I appreciate people writing me and thinking about me. So I was trying to reply to people but also stayed focused on my game. I think I dealt with it pretty well."

Kuznetsova will next face No. 14 seed Agnieszka Radwanska, who beat russian qualifier Anastasia Pavlyuchenkova in straight sets, 62 63. Next up for Serena is unseeded Bethanie Mattek, who demolished No. 11 seed and last year's finalist Marion Bartoli.

"It was pretty cool being able to beat last year's finalist today; she's a good player and she's tough on grass, so I'm really excited," said Mattek, whose win over the world No.10 was her career-first Top 10 win. "I haven't played Serena in a couple years. She's a tough competitor. I'll have to be on my A-game, for sure. I think it will come down to serving big and then seeing who can break."
