French Open 2018: Rafael Nadal beats Maximilian Marterer in last 16

Rafael Nadal won the French Open in 2005, 2006, 2007, 2008, 2010, 2011, 2012, 2013, 2014 and 2017

Ten-time French Open champion Rafael Nadal moved into the 2018 quarter-finals with a 6-3 6-2 7-6 (7-4) victory over Germany's Maximilian Marterer.

Nadal, 32, lost his opening service game and trailed 2-0 in the first set in Paris before recovering well.

He broke Marterer's serve early in the second set and fought back from 3-1 down in the third for a straight-set win against the unseeded 22-year-old.

The Spaniard will play 11th seed Diego Schwartzman, 25, in the last eight.

The Argentine recovered from two sets down to beat South African sixth seed Kevin Anderson 1-6 2-6 7-5 7-6 (7-0) 6-2 to move into the second Grand Slam quarter-final of his career - and first at Roland Garros.

His compatriot Juan Martin del Potro also moved into the last eight with a 6-4 6-4 6-4 win over American ninth seed John Isner.

He will play third seed Marin Cilic, who overcame Italian 18th seed Fabio Fognini 6-4 6-1 3-6 6-7 (4-7) 6-3. The Croat had led by two sets before his opponent played some brilliant tennis, particularly in the tie-break, to draw level.

However, Cilic, who has never progressed beyond the last eight at Roland Garros, broke his opponent in the fifth game of the final set before going on to seal victory.

I don't feel old - Nadal

Nadal, meanwhile, has reached at least the quarter-finals in 12 of the 14 years he has played in the French Open.

The world number one has won 37 consecutive sets in the tournament, though he needed a tie-break in the third set to secure Monday's win over world number 70 Marterer.

Nadal, who celebrated his birthday on Sunday, is now third on the all-time list for most match wins at Grand Slams, moving clear of Jimmy Connors with his 234th.

"I don't feel old, but I am 32, and I have been here since 2003, so it's a long way, a lot of years," said Nadal.

"I started very young. That's a real thing. But, no, I feel happy to be here. I hope to keep doing this for a while."

Schwartzman delight at 'David and Goliath' win

Diego Schwartzman (front) reached the last eight of the US Open in 2017 in his only other Grand Slam quarter-final

Schwartzman, who is 5ft 7in, said his victory over 6ft 8in Anderson was like "David and Goliath".

"I read it when I was young in school, and I just try to think that when I see Kevin or the guys who are two metres (tall)," he said.

"When you're not as strong or you're not as tall as Anderson, you can still win the match. I think people like me more, as well, for that, because they were supporting me.

"They wanted me to remain in the game and the fact he was twice as tall as me was a reason for me to try and remain. But you can have a very good serve whether you're tall or small. That didn't have anything to do with it."

Nadal, who has won all his five previous meetings with Schwartzman, said of the Argentine: "It's always good to see him in the quarter-final because he's a good friend, a good person.

"He's a worker, and I'm happy to see him having all this success. Hopefully not too much."
