Nadal, Wozniacki in quarterfinals

Defending champion Spain's Garbine Muguruza reacts as she plays France's Kristina Mladenovic during their fourth round match of the French Open tennis tournament at the Roland Garros stadium, Sunday, June 4, 2017 in Paris.

These two have met three times before and Nadal won all three matches.

The 31-year-old Nadal is chasing his 15th Grand Slam title and first since 2014 - when he won at Roland Garros.

The nine-time champion matched Roger Federer's Open era record for appearances in the last eight at Roland Garros.

Bacsinszky won 5-7, 6-2, 6-1 in Court Philippe Chatrier, the second year in a row that she beat Williams in the fourth round in Paris.

The 14-time grand slam champion clenched his fist after taking the first set in 37 minutes with a vicious forehand victor and led 3-1 in the second after charging in to guide a backhand victor when Bautista Agut struck the net cord. In the last 16 the Serb faces Albert Ramos-Vinolas, whose best Grand Slam run came when he made last year's French Open quarter-finals.

Caroline Wozniacki, with two slam finals now the most experienced player left, continued her fine year with a surprise 6-1 4-6 6-2 victory over 2009 victor Kuznetsova. It is the first time in a completed match at the tournament that Nadal has only lost one game.

Earlier in the day, Kei Nishikori avoided an upset in his rain-interrupted match, as he eventually overcame Chung Hyeon in five sets.

She said: "I lost confidence, and my opponent was on home turf, so it created a lot of tension".

Bautista Agut was doing his best to fend off his rampant compatriot, but Nadal gave him no chance with another searing forehand before a double fault gifted the world number four a 5-2 lead and he served out a second set in which he dropped just the solitary point on serve.

Karen Khachanov will play Andy Murray in the fourth round after the giant Russian beat American 21st seed John Isner 7-6 (7/1), 6-3, 6-7 (5/7), 7-6 (7/3).

Carina Witthoeft turned up late for her third round match against second-seeded Karolina Pliskova at the French Open.

Elsewhere in the women's draw, Svitolina continued her march towards a first Grand Slam title, edging out Poland's Linette in two evenly matched sets of tennis.
