London, England - Fourth-seeded former runner-up Agnieszka Radwanska was sent packing, while former champion Petra Kvitova secured a berth in another Wimbledon quarterfinal on Monday.
Russian left-hander Ekaterina Makarova, seeded 22nd, leveled the sluggish Polish star Radwanska in 6-3, 6-0 fashion in fourth-round action on the No. 3 Court.
Radwanska reached the final here two years ago, but lost to Serena Williams.
The sixth-seeded Czech lefty Kvitova blew past Chinese Peng Shuai 6-3, 6-2 to reach the round of eight here for a fifth year in a row. Kvitova was the Wimbledon champ in 2011 and reached the semifinals the year before that.
Her quarterfinal opponent will be surprise fellow Czech Barbora Zahlavova Strycova.
Former world No. 1 Caroline Wozniacki exited the draw, losing 6-2, 7-5 to the unseeded Zahlavova Strycova on Day 7.
Zahlavova Strycova finished with a lopsided 31-11 advantage in winners and advanced to her first Grand Slam quarterfinal on her sixth match point. She had not taken a set in three previous meetings with her 16th-seeded Danish counterpart.
The 43-ranked Zahlavova Strycova has now beaten seeded players in three consecutive matches.
Wozniacki has never made it past the fourth round at the All England Club.
Lucie Safarova beat Tereza Smitkova 6-0, 6-2 in an all-Czech fourth-round matchup.
The 23rd-seeded Safarova will meet Makarova in the quarterfinals.
Czech women went 3-1 on Monday, with the only loss coming in the all-Czech Safarova-Smitkova affair, and this marks the first time that three Czech women have reached the quarterfinals at Wimbledon.
In some third-round action on Day 7, 19th-seeded German slugger Sabine Lisicki upset 11th-seeded former world No. 1 Ana Ivanovic 6-4, 3-6, 6-1. Ivanovic captured her first-ever grass-court title a few weeks ago in Birmingham, but has never fared well on the lawns at Wimbledon, having failed to get past the fourth round here now the last seven years.
Lisicki, meanwhile, thrives on the grass at the AEC, where she was last year's surprise runner-up and reached at least the quarterfinals here in her previous four trips.
Up next for the German will be Kazakhstan's Yaroslava Shvedova, who moved on when American Madison Keys pulled out of their third-round match because of a left thigh injury. The two were scheduled to complete their match on Monday after Shvedova took the first set 7-6 (9-7) and things were tied at 6-6 in the second set before darkness forced the suspension of play on Saturday.
Keys' exit leaves the women's draw without any Americans, and for the first time since 1911, there are no Americans, male of female, playing in the fourth round at Wimbledon.
Two quarterfinals will be staged on Tuesday, as Kvitova will tangle with Zahlavova Strycova and Makarova will battle Safarova.
And the fourth round is scheduled to conclude on Tuesday, as third-seeded French Open runner-up Simona Halep will face Kazakhstan's Zarina Diyas, fifth- seeded French Open champ Maria Sharapova will battle ninth-seeded German Angelique Kerber and Lisicki will take on Shvedova. Sharapova captured her lone Wimbledon title in 2004 and was the 2011 runner-up here to Kvitova.
