Ivanovic crashes out of Wimbledon

Number one seed Ana Ivanovic has crashed out of Wimbledon losing in straight sets to Jie Zheng of China.

The 20-year-old Serb was punished for an error-strewn display by being dumped out with a 1-6 4-6 defeat by Jie Zheng, a player ranked 133 in the world.

Earlier, Roger Federer successfully navigated the third round and the first week at Wimbledon, sailing past French challenger Marc Gicquel 6-3 6-3 6-1.

The world number one needs four more victories in the second week to set a modern era record of six men's titles in a row and on this showing is in no mood to let the opportunity slip.

He captured the first set with a booming ace and the second, after two breaks of serve, with a screaming forehand winner.

With the 53rd-ranked Gicquel completely out of his depth, the Swiss master sailed through the third with two breaks to claim his 61st grasscourt victory in a row.

Meanwhile, Czech Nicole Vaidisova continued to rediscover her form, beating Australian Casey Dellacqua 6-2 6-4 in a third round clash.

Vaidisova, a quarter-finalist here last year, has suffered a mid-season slump since reaching the fourth round of the Australian Open but was too strong for Dellacqua, Australia's last survivor in the women's singles.

Wimbledon's first lengthy rain delay stalled Vaidisova's serene progress when she led 6-2 4-3 but the 19-year-old returned to complete the victory with the minimum of fuss.

Vaidisova has been bad news for Australians at this year's championships as she also ended Samantha Stosur's hopes in the second round despite dropping the second set 6-0.

The 19-year-old Vaidisova, who suffered five consecutive first round defeats earlier this year, said: "It's always tough being in the lead, coming back after an hour or so. But I think I handled it very well.

"I made some changes in my team, a new coach, but the changes needed some time. It doesn't come overnight, so I'm definitely happy it's paying off and I'm showing some progress.

"I'm a pretty positive person, so I always kind of believe it's going to come back eventually."

Twice grand slam semi-finalist Vaidisova, who is now working with David Felgate, the former coach of British favourite Tim Henman, will face Anna Chakvetadze in the last 16 after the eighth seed beat fellow Russian Evgeniya Rodina 6-4 6-3.
