Kvitova in, Sharapova out at Wimbledon WIMBLEDON, England, July 2 (UPI) -- Reigning champion Petra Kvitova moved into the Wimbledon quarterfinals but world No. 1 Maria Sharapova and Belgian star Kim Clijsters were eliminated Monday. Kvitova rallied for a 4-6, 7-5, 6-1 victory over 24th-seeded Italian Francesca Schiavone to claim her 11th straight win at the All-England Lawn and Tennis Club. She used 13 double-faults from the 2010 French Open champ to her advantage. Also posting a victory Monday was four-time winner Serena Williams, who also had to stage a comeback in her 6-1, 2-6, 7-5 triumph over Russia's Yaroslava Shvedova on a cold and rainy day in suburban London. Williams and Kvitova will face each other in the round of eight Tuesday. Sharapova, meanwhile, fell to 15th-seeded German Sabine Lisicki 6-4, 6-3. The big-serving German avenged her semifinal loss against Sharapova in last year's Wimbledon semifinals. Lisicki fired six aces and broke Sharapova four times in the 84-minute match. Unseeded Clijsters, who has announced her intention to retire, fell hard to eighth-seeded German Angelique Kerber 6-1, 6-1, who now moves on to battle Lisicki in an all-German round-of-eight match. Clijsters, 29, will retire from tennis for a second time following this year's U.S. Open. Also notching wins Monday were second-seeded Victoria Azarenka of Belarus, third-seeded Pole Agnieszka Radwanska, 17th-seeded Russian Maria Kirilenko and No. 21 seed Tamira Paszek of Austria.
