Surprise French Open champion Jelena Ostapenko has joined Svetlana Kuznetsova in the Wimbledon quarter-finals after a thrilling fourth-round win over fourth seed Elena Svitolina.

Svitolina saved seven match points before finally succumbing 6-3 7-6 (8-6) after one hours and 44 minutes on Monday.

Ostapenko is the first first-time major champion to progress to the last eight at the ensuing grand slam since Kim Clijsters made the 2006 Australian Open semi-finals after winning the 2005 US Open.

Bidding to complete a rare “Channel Slam”, the Latvian history-maker will play either five-time champion Venus Williams or Croatian Ana Konjuh in Tuesday’s quarter-finals.

Dual grand slam champion Kuznetsova earlier outclassed former finalist Agnieszka Radwanska in straight sets to be the first woman through to the last eight.

The Russian seventh seed won 6-2 6-4 in one hour and 31 minutes and will face either world No.1 Angelique Kerber or 2015 runner-up Garbine Muguruza in her fourth quarter-final at the All England Club – but first in a decade.

Unseeded Slovak Magdalena Rybarikova is also through after ending the run of Croatian qualifier Petra Martic with a 6-4 2-6 6-3 victory.

Rybarikova awaits the winner of the fourth-round match between fifth seed Caroline Woizniacki and Pat Cashed-coached American Coco Vandeweghe.
