Yaroslava Shvedova completed the first Golden Set in Grand Slam history as the Kazakh wildcard won all 24 points and conceded none in a 6-0 first set whitewash against Sara Errani at Wimbledon on Saturday.

Shvedova, the world number 65, hit 14 winners and took just 15 minutes to demolish Italian 10th seed Errani, the French Open runner-up, in an incredible first set.

The 24-year-old, the Wimbledon doubles champion in 2010 and twice a French Open quarter-finalist, couldn't dominate quite so emphatically in the second set.

But she still landed the decisive break to secure a 6-0, 6-4 victory in 57 minutes to reach the last 16. "Today I laid a golden egg," Shvedova tweeted. The only previous player to record a Golden Set was American Bill Scanlon, who won all 24 points in the second set of his 6-2, 6-0 first round defeat of Marcos Hocevar of Brazil at Delray Beach in 1983.

Serena, Kvitova in last 16
Meanwhile, four-time champion Serena Williams clinched a marathon triumph over China's Zheng Jie to reach the Wimbledon last 16.u00a0The US sixth seed showed her grit to come back from a set down to win 6-7 (7/5), 6-2, 9-7 on Centre Court to propel her into the fourth round. Defending champion Petra Kvitova wasted little time moving into Wimbledon fourth round as the Czech took just 53 minutes to crush America's Varvara Lepchenko 6-1, 6-0.

Rosol's dream ends
Lukas Rosol, the shock Wimbledon conqueror of Rafael Nadal, returned to familiar anonymity when Germany's Philipp Kohlschreiber sent him crashing out in the third round.

Czech world 100 Rosol had caused one of the greatest upsets in the history of the sport when he beat world number two Nadal in five sets in the second round under the Centre Court roof on Thursday.

But, in the less glamourous surroundings of Court 12, normal service was resumed as German 27th seed Kohlschreiber, who had also beaten Nadal on grass at Halle two weeks ago, eased to a 6-2, 6-3, 7-6 (8/6) victory and a first appearance in the fourth round. u00a0
