LONDON (AP) -- Less than 24 hours after knocking Serena Williams out of Wimbledon, Sabine Lisicki made quick work of her next opponent, topping Kaia Kanepi 6-3, 6-3 in 61 minutes Tuesday.
The 23rd-seeded Lisicki advanced to her second Wimbledon semifinal.
Lisicki broke Kanepi in the first game and didn't look back in the opening set. She double-faulted three times in the third game of the second set to lose serve for the first time but broke right back, then won four of the next five games.
Radwanska moved a win away from her second straight Wimbledon final, defeating Li Na 7-6 (5), 4-6, 6-2 on Tuesday in a match that took nearly 3 1/2 hours to complete, including two rain delays, an injury timeout and a 10-minute final game.
Radwanska won on her eighth match point to close out a game in which she also saved three break points.
Last year, Radwanska became the first Polish woman since 1939 to reach a Grand Slam final before she fell to Serena Williams.
Radwanska had 18 unforced errors to 40 for Li, who won the 2011 French Open.
Marion Bartoli of France eliminated the last U.S. player at Wimbledon on Tuesday, reaching her third Grand Slam semifinal by beating Sloane Stephens 6-4, 7-5 in a rain-interrupted, break-filled match.
The 15th-seeded Bartoli, the 2007 runner-up at the All England Club, was leading 5-4 with Stephens serving at deuce when they resumed after a 2 1/2-hour rain delay. Bartoli won the next two points, the latter a 27-stroke exchange, to take the opening set.
That began a stretch in which Bartoli broke Stephens five consecutive times, four at love. After Stephens broke to get within 5-4, then held to 5-all, Bartoli took the last two games, including yet another break at love to end the quarterfinal.
Kirsten Flipkens upset former champion Petra Kvitova 4-6, 6-3, 6-4 to reach the Wimbledon semifinals on Tuesday.
Playing in her first Grand Slam quarterfinal, the bespectacled Flipkens had only five unforced errors in a gutsy performance. She fell face first on the court and kissed the grass after closing out the match with an ace that was challenged by Kvitova.
Flipkens said "It's ridiculous! Last year I didn't even get into qualifying. To be a semi-finalist at Wimbledon, it cannot be better."
The No. 20 Flipkens will next play Marion Bartoli.
Kvitova, who won the title at the All England Club two years ago, called for a medical timeout at 5-2 in the second set and had her temperature checked.
