Serena Williams Ousted in Fourth Round at Wimbledon

LONDON (AP) —The stunning string of upsets at Wimbledon continues into the second week. Defending champion Serena Williams lost in the fourth round, falling 6-2, 1-6, 6-4 to Sabine Lisicki of Germany.

The loss ended Williams' career-best 34-match winning streak and her attempt to capture a sixth title at the All England Club.

Williams was up a break twice in the third set but Lisicki fought back both times and broke again to go ahead. She converted her second match point with a forehand winner.

In other play on a busy day at the All England Club, former champion Petra Kvitova became the first player to reach the quarterfinals, beating Carla Suarez Navarro of Spain 7-6, 6-3.

She was joined minutes later by Kirsten Flipkens of Belgium, who reached her first career Grand Slam quarterfinal by ousting Flavia Pennetta of Italy 7-6, 6-3. Li Na routed Roberta Vinci of Italy 6-2, 6-love to reach the quarterfinals for the third time.

Fourth-seeded David Ferrer overcame another slow start with a 6-7, 7-6, 6-1, 6-1 victory over Ivan Dodig of Croatia.

All fourth round matches in men's and women's play are on the schedule.
