WIMBLEDON, England -- Kim Clijsters has played her last Wimbledon match, losing in straight sets to eighth-seeded Angelique Kerber of Germany in the fourth round.
Clijsters is retiring after this year's U.S. Open and went out with a whimper on Court 3, winning just two games as Kerber overpowered her 6-1, 6-1.
The Belgian four-time Grand Slam winner never earned a break point and saved a match point when serving at 5-0 in the second set. Kerber than served out the match at love.
Klijsters gave a brief wave to the crowd as she walked off the court to a loud round of applause. She was trying to advance to her fourth Wimbledon quarterfinal, but never reached the final at the All England Club.
Williams cruised through the first set in windy conditions before the hard-hitting Shvedova found her rhythm in the second, breaking the sixth-seeded American twice to level the match. Williams then wasted three break points at 4-4 in the third before eventually breaking for a 6-5 lead. After nearly two hours, she clinched the victory with a backhand winner on her first match point.
In her third-round match, Williams won the last set 9-7 against Zheng Jie.
Shvedova, a wild-card entry, became the first woman in the Open Era to win a set without losing a single point in her third-round match against Sara Errani.
Williams will next face Petra Kvitova. The defending champion on Monday overcame an error-filled performance to rally from a set and a break down and outlast Francesca Schiavone 4-6, 7-5, 6-1 to reach the quarterfinals at Wimbledon.
In a matchup of two former Grand Slam winners, both players struggled to control the windy conditions on Court 3, and Kvitova wasted 10 break points in the first set. She finally broke back for 2-2 in the second when Schiavone double-faulted. However, the fourth-seeded Czech took charge by jumping out to a 5-0 lead in the third set and served out the match at love.
Schiavone, the 2010 French Open winner, won the first set despite hitting just two winners and making 16 unforced errors. Kvitova then won the second despite having four winners and 14 unforced errors.
