London: Bride-to-be Dominika Cibulkova sent world number three Agnieszka Radwanska crashing out of Wimbledon on Monday, while Australian Open champion Angelique Kerber cruised into the quarter-finals.
Cibulkova defeated Poland's Radwanska en route to her first grass-court title at Eastbourne last month and emulated that result with a surprise 6-3, 5-7, 9-7 fourth round victory to secure her first Wimbledon quarter-final berth since 2011.
The 27-year-old will play Russian world number 50 Elena Vesnina or Russian world number 35 Ekaterina Makarova for a place in her first Wimbledon semi-final.
Cibulkova cried tears of joy as she rolled on the court in celebration after the final point, but the triumph could come with a sting in the tail as she will have to postpone her wedding if she makes it to Saturday's final.
The 2014 Australian Open runner-up is due to get married to fiancé Miso Navara in Bratislava on the same day after planning the big occasion nine months ago.
Radwanska, beaten in the 2012 Wimbledon final, is still waiting for her first Grand Slam title.
German fourth seed Kerber cruised into her third Wimbledon quarter-final with a 6-3, 6-1 thrashing of Japanese world number 49 Misaki Doi.
Kerber, who won her maiden Grand Slam crown in Melbourne in January, has yet to drop a set in four matches and could leave Wimbledon as the world number one if she wins the title and Serena Williams fails to make the semi-finals.
"I'm feeling my tennis is getting better and better every day. This is what counts in the second week of a Grand Slam," Kerber said.
"It's important for my confidence. But I know I have still a long way (to win Wimbledon). I have to play really good."
Kerber plays Romania's Simona Halep, who fought back to reach her second Wimbledon quarter-final with a 6-7 (5/7), 6-4, 6-3 victory against American ninth seed Madison Keys.
Fifth seed Halep, a former French Open runner-up, made the semi-finals at the All England Club in 2014.

Russian 21st seed Anastasia Pavlyuchenkova, who celebrated her 25th birthday on Sunday, reached her first Wimbledon quarter-final with a 6-3, 6-3 win over Coco Vandeweghe of the United States.
After conquering her dislike of grass, she faces defending champion Serena or Russian 13th seed Svetlana Kuznetsova for a place in the semi-finals.
"I'm not supposed to say this, but really I didn't like grass at all. Now it's kind of changing a little," Pavlyuchenkova said.
Later on Monday, Serena and sister Venus Williams will aim to get the Fourth of July celebrations in full swung by advancing to the quarter-finals.
With American Independence day festivities underway, world number one Serena and five-time Wimbledon champion Venus are the last women flying the stars and stripes flag at the All England Club.
Serena was due to face Kuznetsova on Centre Court as she looks to move a step closer to winning a record-equalling 22nd major title by lifting the Wimbledon trophy for a seventh time.
Venus will be in action on Court One against Spanish 12th seed Carla Suarez Navarro as she targets her first Wimbledon quarter-final since 2010.
At 36 years and 17 days, eighth seed Venus is the oldest woman to appear in the last 16 at Wimbledon since Martina Navratilova 22 years ago.
Venus won the last of her seven Grand Slam titles when she lifted the Wimbledon trophy for a fifth time in 2008 and hasn't made the semi-finals of a major since the 2010 US Open.
If the Williams siblings both win, it will be the first time since 1999 that more than one player aged 30 or over reached the Wimbledon quarter-finals.
Lying in wait for Venus or Suarez Navarro is Kazakhstan's Yaroslava Shvedova, who reached her first Wimbledon quarter-final with a 6-2, 6-4 win over Czech 28th seed Lucie Safarova.
World number 96 Shvedova is the lowest ranked player left in the women's tournament.
