Murray takes on tricky Khachanov for a spot in last eight

Wawrinka took a medical timeout midway through the second set, laying down on the sideline and getting massaged by a trainer, but then played well the rest of the way, using his sweet-swinging one-handed backhand to great effect. "They gave me the energy to fight".

Top seed Andy Murray eased into the last-16 of the French Open with a 7-6 (10-8) 7-5 6-0 victory over a flagging Juan Martin del Potro.

But the biggest for the day could very well be Andy Murray against Juan Martin Del Potro!

The match turned late in the first set when Del Potro failed to serve it out and Murray eventually took the tie-break with his third set point, having saved four.

"I just try to find myself into this zone where I don't do much unforced errors", the Ukrainian said, "and still play aggressive". Admittedly, Khachanov has never won successive grand-slam matches until this tournament.

"Look, regardless of how someone reacts, necessarily", Murray said, "you still have to expect that they are going to come out and start the (next) set strong".

HOW THE AUSSIES FARED: Nick Kyrgios and Jordan Thompson were bounced in the third round of the men's doubles - Ash Barty and Casey Dellacqua won their round two women's doubles match. The next came at 5-4, but he netted a backhand, then double-faulted to grant a break point that Murray claimed with a forehand victor.

"It was a good one for me to get through".

The third-seeded Romanian took care of that problem on Monday at the French Open, routing Suarez Navarro 6-1, 6-1 to advance to the quarterfinals at Roland Garros.

"Whoever won that first set had big momentum", said the British tennis player after the match.

He had two set points at 5-3 before Murray clawed it back level by converting his sixth break point.

But while the popular Del Potro will be best remembered for helping injured opponent Nicolas Almagro in his previous match, the good news is that he's bolstering his game.

"The conditions were very slow and heavy so coming from behind in those conditions can be difficult because it feels you have to work very hard for every point", he added. "Sometimes I feel I'm under pressure during the whole match", said Nadal.

In the undulating tiebreak the world number one led 4-6, misdirected a forehand at the net, and then gratefully received a double fault at 6-7.

Alize Cornet upset ninth seed Agnieszka Radwanska 6-2 6-1 to set up an all-French fourth-round clash with Caroline Garcia, who beat Taiwan's Hsieh Su-wei 6-4 4-6 9-7.

"My service was not hurting him as much any more later into the match". But it still was extremely complicated, because he was starting to return the balls better.

Murray did enough to keep his nose in front throughout, while the Argentine was unable to reprise the heroics that saw the pair produce such magic in last year's Rio Olympics gold medal match.
