Radwanska Moves Into Semifinals at Wimbledon

Last year's runner-up, Agnieszka Radwanska, moved into the semifinals, while 2011 champion Petra Kvitova joined the list of upset victims at Wimbledon Tuesday.  The fourth-seeded Radwanska held off sixth-seeded Chinese star Li Na 7-6 (7-5),  4-6, 6-2, while 20th-seeded Belgian Kirsten Flipkens upended the eighth-seeded  Kvitova in 4-6, 6-3, 6-4  fashion on the famed grass of Centre Court, where the retractable roof was closed because of rain on Day 8. Up next for the surprising Belgian will be 15th-seeded  Frenchwoman Marion Bartoli, who  took out  the last  American still standing  at the All England Club, 17th-seeded Sloane Stephens, 6-4, 7-5, following a lengthy rain delay on Court 1. Meanwhile, less than 24 hours after stunning the world No. 1, defending champion and five-time overall Wimbledon titlist Williams, the 23rd- seeded  Sabine  Lisicki stayed hot at this fortnight and reached her second semifinal  here in three years by tackling Estonian Kaia Kanepi 6-3, 6-3 in 64 minutes on Court 1. The 23-year-old German broke Kanepi four times, while the Estonian managed only one break in the setback.

The men's quarterfinals will take place Wednesday as top seed and  former Wimbledon champion takes on No. 7 seed Tomas Berdych. Second seed Andy Murray, who lost to Djokovic in this year's Australian Open and was the runner-up at the  All-England club last year, faces Fernando Verdasco. Fourth seed David Ferrer and formidable 6-foot-7 Argentine Juan Martin del Potro will face each other on Wednesday. Also, a battle of players from Poland will see No. 24 seed Jerzy Janowicz take on Lukasz Kubot.  It will be the first-ever all-Polish Grand Slam quarterfinal, with the winner giving  Poland its first-ever male Grand Slam semifinalist.
