Roger Federer recorded a fine win in his 400th Grand Slam match on Friday

Roger Federer continued his straightforward progress through the French Open draw with a 6-2, 6-3, 6-3 victory over Argentina's Leonardo Mayer on Sunday. But he hadn't been past the fourth round at a Slam since, in part because he missed time after knee surgery.

The 20-time Grand Slam victor eased through with a 6-2, 6-3, 6-3 win Sunday against unseeded Argentine Leonardo Mayer.

One more win and Federer will be right back where he left off on his last trip to Paris in 2015 - the quarterfinals. "I was able to put pressure on him and I'm very happy with my performance", Federer said.

Bad light meant Stefanos Tsitsipas' match against Filip Krajinovic, as well as the clash between Grigor Dimitrov and Stan Wawrinka, had to be halted before reaching a conclusion, meaning they will have to return to the court on Saturday.

But despite the heartbreaking and exhausting manner of the defeat, the world number six, who started the year ranked 15th, said he would not want men to play fewer sets at Grand Slam tournaments.

Roger Federer's return to Roland Garros after a four-year absence could not have gone better through three matches.

It was the second time Federer has beaten Mayer at a Grand Slam - the other also coming in straight sets, in the first round of the U.S. Open in 2015.

After just over an hour in his match, Federer was already two sets up but Mayer offered some semblance of resistance in the third until the sixth game, when Federer, 37, broke decisively, ending his opponent's ordeal on the first match point. "Rod Laver was my idol a handsome player to watch, but this guy he is the most elegant, spectacular, makes it look easy, just the most attractive player that I've ever seen play this game", said the American on the Swiss.

Defending champion Rafael Nadal was equally impressive during a 6-2 6-3 6-3 win over Argentine debutant Juan Ignacio Londero, reaching his 38th Grand Slam quarter-final. "I'm just happy with my game". Open champion Sloane Stephens who downed former champion Garbine Muguruza 6-4, 6-3 to book her place in the quarterfinals.

Kei Nishikori needed over four hours to beat Laslo Djere 6-4 6-7 (8-10) 6-3 4-6 8-6 to go through to the next round.

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

"I feel fortunate to have played in the why I did against a player like Donna", she said. Federer also became the third oldest man to reach the last eight at Roland Garros.
