Roger Federer cruises through against Leonardo Mayer

Roger Federer 'Playing against a guy like Casper Ruud is so nice'

Federer won his only French Open in 2009, the year Nadal lost to big-serving Swede Robin Soderling in the fourth round. That also happens to be the last time the 34-year-old beat the 20-time Grand Slam champion.

After a cool first week the thermostat was turned up at Roland Garros on Friday as Rafael Nadal and Roger Federer both blazed a trail into the French Open fourth round for the 14th time.

While Federer did not face a single break point in beating Mayer for the fourth time in four meetings, Nadal dropped his serve once - late in the third set - and saved four other break-point chances in his first-ever match against the quick-hitting Londero.

Wawrinka edged Tsitsipas 7-6 (6), 5-7, 6-4, 3-6, 8-6 after 5 hours and 9 minutes of breathtaking tennis in sweltering heat to reach the quarter-finals at a Grand Slam tournament for the first time in two years. "You don't want to be in my place", Tsitsipas said.

"It's fabulous that I can spend this time in Paris", said Federer, who last played the tournament in 2015 when he lost in the quarterfinals to Stan Wawrinka. "He beat me in three sets with his awful shorts". At 37, he is the oldest man to make the quarter-finals of a Slam since Jimmy Connors at the 1991 US Open.

Of Wawrinka he said: "On clay, it's been definitely more risky than on any other surface for me against him".

The 31st-seeded Croat next faces Czech teenager Marketa Vondrousova, who reached her first quarterfinal at a major without dropping a set.

"I have a bad memory of it. Stan beat me in three sets with his awful shorts!"

The two women's quarterfinals established Sunday: 2017 U.S. Open champion and 2018 French Open runner-up Sloane Stephens vs.

The Mallorcan second seed was never in serious trouble, however, and came through 6-1 6-3 4-6 6-3 to set up a clash with Argentina's 78th-ranked Juan Ignacio Londero.

The Spaniard, who turns 33 on Monday, has only been defeated twice in his French Open career and has a 10-2 record over Nishikori while he has yet to lose to Paire in four matches.

He will face the victor of the match between Kei Nishikori and Benoit Paire, which was stopped for bad light with the Japanese seventh seed leading 6-2, 6-7 (8-10), 6-2.

The American, a former US Open victor, needed five match points to get over the line. Federer also became the third oldest man to reach the last eight at Roland Garros.

British number one Johanna Konta continued her comfortable progress through the draw by seeing off Croatia's Donna Vekic to reach her first Grand Slam quarter-final since Wimbledon in 2017.
