Agnieszka Radwanska, Li Na and Sabine Lisicki all won three-set matches in the third round on Saturday at Wimbledon.
Radwanska, the fourth seed and last year's runner-up, battled past American Madison Keys, 7-5, 4-6, 6-3, while the sixth-seeded Li came back from a set down to earn a 4-6, 6-0, 8-6 triumph over Klara Zakopalova of the Czech Republic.
Lisicki, meanwhile, knocked off former U.S. Open champ Samantha Stosur with a 4-6, 6-2, 6-2 decision. Next up for Lisicki, who reached the 2011 Wimbledon semifinals and was twice a quarterfinalist, could be top-seeded Serena Williams, who was set to play a late match against Japanese veteran Kimiko Date-Krumm.
Radwanska's next opponent will be Bulgaria's Tsvetana Pironkova, a 6-1, 4-6, 6-2 winner over Croatia's Petra Martic. Pironkova's only Grand Slam success has come at the famed lawns of the London suburb. She's never been past the second round at the Australian Open or French Open and has had one run to the fourth round in seven tries at the U.S. Open. However, she was a Wimbledon semifinalist in 2010 and a quarterfinalist in 2011.
Li will meet Italian 11th seed Roberta Vinci in the fourth round on Monday. The 2011 French Open champ from China is into the second week at Wimbledon for just the third time in seven visits, with quarterfinal appearances in 2006 and 2010 her best results.
Vinci advanced Saturday with a 6-1, 6-4 rout of Slovakia's Dominika Cibulkova.
Also Saturday, British crowd favorite Laura Robson rallied from a set and a break down to beat New Zealand's Marina Erakovic. The 1-6, 7-5, 6-3 win lifted Robson into a fourth-round match against Estonia's Kaia Kanepi, a 6-2, 6-3 winner over American Alison Riske.
"I just tried to put the pressure on her serve, and she made a couple of double faults, which helped me," said Robson about coming back against Erakovic. "I knew that that was my chance to get in her head a little bit, and that's what I did."
Petra Kvitova and Sloane Stephens were among the early winners Saturday in matches that were halted Friday due to darkness.
Kvitova, the 2011 champ and this year's eighth seed, trailed in the third set of her match against Russian Ekaterina Makarova on Friday, but the Czech star dominated when play resumed. She dropped just one game Saturday and advanced with a 6-3, 2-6, 6-3 triumph.
"I didn't have a good night's sleep," mused Kvitova. "The match was still in my mind, what was good and bad. Today was another day for me. I played aggressively and that was the key."
Next up for Kvitova will be Spain's Carla Suarez Navarro, who completed her third-round win Friday against Canada's Eugenie Bouchard.
Stephens also had her match halted by darkness Friday after splitting the first two sets with Petra Cetkovska, but the 17th-seeded American managed to pull out a 7-6 (7-3), 0-6, 6-4 victory.
Just 20 years old, Stephens has now reached at least the fourth round of each Grand Slam this year. She was a surprise semifinalist at the Australian Open after beating Williams in the quarters and lost to Maria Sharapova in the French Open fourth round.
Monica Puig will be the fourth round opponent for Stephens on Monday. The Puerto Rico native upset fifth-seeded Sara Errani in the first round and completed her first week at the All England Club with a 4-6, 6-3, 6-4 win over Eva Birnerova of the Czech Republic in another match stopped Friday by darkness.
