Slovakian 19th seed Dominika Cibulkova sent world number three Agnieszka Radwanska crashing out of Wimbledon with a surprise 6-3, 5-7, 9-7 fourth round victory on Monday.

Cibulkova defeated Poland's Radwanska en route to her first grass-court title at Eastbourne last month and emulated that result in a high-quality clash to secure her first Wimbledon quarter-final berth since 2011.

The 27-year-old, who has never made the last four at the All England Club, will play Russian world number 50 Elena Vesnina or Russian world number 35 Ekaterina Makarova for a place in the semi-finals.

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 fiance Miso Navara in Bratislava on the same day after planning the big day nine months ago.

Radwanska, beaten in the 2012 Wimbledon final, is still waiting for her first Grand Slam title after failing to make the quarter-finals at the All England Club for only the second time in the last five years.
