London, England (SportsNetwork.com) - Former Wimbledon runner-up Agnieszka Radwanska and 2011 titlist Petra Kvitova were third-round winners, while Australian Open champion and second-seeded Li Na was ousted Friday at The Championships.
Czech Barbora Zahlavova Strycova stunned two-time Grand Slam champion Li 7-6 (7-5), 7-6 (7-5) to reach the fourth round of a major for the first time in her career.
"I believed in myself coming into this match and I felt I could (win) and that it would happen," said Zahlavova Strycova. "I'm really glad I could pull through."
Next up for Zahlavova Strycova is 16th-seeded Caroline Wozniacki, who cruised past teenager Ana Konjuh 6-3, 6-0 in 70 minutes. Wozniacki is still seeking a trip into her first-ever Wimbledon quarterfinal.
The fourth-seeded Radwanska cruised to a 6-2, 6-0 victory over Portugal's Michelle Larcher de Brito. The Polish star was the runner-up at the All England Club two years ago.
Radwanska will face No. 22 seed Ekaterina Makarova in the next round after the Russian bested Caroline Garcia of France by a 7-5, 6-3 margin.
The sixth-seeded left-hander Kvitova outlasted five-time Wimbledon champ Venus Williams 5-7, 7-6 (7-2), 7-5 to improve to an impressive 22-5 lifetime at Wimbledon.
The 34-year-old former world No. 1 Williams hasn't made it to the fourth round at Wimbledon since 2011.
"I did the best I could. I think she played well at every single moment," said Williams. "I gave it my all. Sometimes it's not enough."
Up next for Kvitova is Chinese Peng Shuai, who rallied past American Lauren Davis 0-6, 6-3, 6-3.
Czech Lucie Safarova, the No. 23 seed, handled No. 10 Aussie Open runner-up Dominika Cibulkova 6-4, 6-2, while Czech Tereza Smitkova outlasted Serbia's Bojana Jovanovski 4-6, 7-6 (7-5), 10-8
In second-round action, third-seeded French Open runner-up Simona Halep outlasted Ukrainian Lesia Tsurenko 6-3, 4-6, 6-4 and Swiss Belinda Bencic defeated American Victoria Duval 6-4, 7-5.
