Wimbledon, England (Sports Network) - Another top-10 women's seed has been dispatched at Wimbledon.
Estonia's Kaia Kanepi rallied to beat German Angelique Kerber, the No. 7 seed, by a 3-6, 7-6 (8-6), 6-3 score on Friday. Kerber, a semifinalist at the All England Club last year, joined a surprisingly long list of high seeds who have suffered early exits: No. 2 Victoria Azarenka, No. 3 Maria Sharapova, No. 5 Sara Errani, No. 9 Caroline Wozniacki and No. 10 Maria Kirilenko.
The four top-10 seeds remaining represents the fewest to reach the third round at any Grand Slam in the Open Era.
Kanepi's match was one of three postponed by rain on Thursday, as British crowd favorite Laura Robson was able to reach the third round at Wimbledon for the first time with a 6-4, 6-1 win over Colombia's Mariana Duque-Marino under the closed roof on Centre Court.
The 19-year-old Robson, who knocked off Kirilenko, captured the Wimbledon girls' singles title in 2008.
American Alison Riske also was a second-round winner as she battled back to oust Poland's Urszula Radwanska, 4-6, 6-3, 6-4.
The weather was a factor again Friday, interrupting play at times throughout the day.
When the third round finally got underway, only five matches were completed, while three others were suspended after darkness forced the players off the court.
Marion Bartoli of France, Spaniard Carla Suarez Navarro, Belgian Kirsten Flipkens and Italian Flavia Pennetta all advanced to the round of 16.
The 15th-seeded Bartoli battled past Camila Giorgi 6-4, 7-5, while the 19th- seeded Suarez Navarro became the first Spanish woman to reach the fourth round at Wimbledon since Conchita Martinez in 2001 with a 7-5, 6-2 win over Canadian Eugenie Bouchard.
The 20th seeded Flipkens handled Serbian Vesna Dolonc, 6-4, 6-2, while Pennetta fought back from a sluggish start to beat 29th-seeded Frenchwoman Alize Cornet, 0-6, 7-6 (7-4), 6-2.
Italian Karin Knapp also advanced to the round of 16 with a 7-5, 6-2 triumph over Michelle Larcher De Brito.
Eighth-seeded Petra Kvitova, the 2011 Wimbledon champ, trailed Russian Ekaterina Makarova early in the third set of their third-round match before darkness halted play. Kvitova took the first set 6-3, but dropped the second set before falling behind 1-2 in the third.
American Sloane Stephens also saw her third-round match against Petra Cetkovska suspended due to darkness. Stephens and Cetkovska split the first two sets before play was halted.
One other third-round match was suspended, with Czech Eva Birnerova holding a 6-4, 2-1 cushion against Monica Puig.
