Canadian Milos Raonic caught a break Friday at the French Open as he needed less than a half hour to complete a third-round victory over Spain's Guillermo Garcia-Lopez.

Raonic, the No. 5 seed from Thornhill, Ont., advanced when Garcia-Lopez retired from the match due to a left thigh injury. The Canadian, who was leading 6-1, 1-0 at the time, said he can use the extra rest.

"I'll take it when I can have it," Raonic said. "I've played a lot over the last weeks. I'm playing well. I'm happy with the way I was able to start today. I think I've made good progress and I'm getting better and better each match.

"Now I'm just looking forward to playing in two days."

Garcia-Lopez needed treatment at the end of the first set. Raonic had a 12-2 edge in winners and recorded five aces over the 28-minute contest.

Raonic is the only Canadian left in the singles draws in Paris after both Eugenie Bouchard and Françoise Abanda lost their second-round matches in the women's tournament.

Raonic's next opponent is 20th-seeded Pablo Carreno Busta. The Spaniard advanced by beating No. 11 Grigor Dimitrov in straight sets.

"I watched a bit of his match today, he's playing well," Raonic said. "He's improved a lot over the last 16 months or so. I played him a few times toward the end of last year. He's very solid, he's disciplined, he shows up and he's there and he doesn't exit the match, you really have to beat him.

"You have to take it to him. So it's going to be about trying to get control and trying to hold on to it throughout the match."

Raonic did not drop a set in their three previous head-to-head meetings. He won on grass at Wimbledon last year and beat him twice on hardcourts later in the season.

Raonic is making his sixth career appearance at Roland Garros. His best result came in 2014 when he reached the quarter-finals.

Djokovic storms back

Defending men's champion Novak Djokovic reached the fourth round after rallying to beat Diego Schwartzman 5-7, 6-3, 3-6, 6-1, 6-1.

Djokovic sealed victory on his first match point with a forehand winner down the line, completing the win in 3 hours, 19 minutes.

The second-seeded Serb gave Schwartzman a hug and a part on the head at the net — and then joined in the applause as the Argentine player walked off Court Philippe Chatrier.

"I was expecting a difficult game with a lot of rallies from the baseline, because the conditions are heavy," Djokovic said moments after his win. "I want to congratulate Diego for a great battle, because he played very well."

Schwartzman needed some treatment to his back late in the fifth set.

Nadal nearly scores triple bagel

Rafael Nadal dropped just one game on his way to a straight-sets victory over Nikoloz Basilashvili.

It was Nadal's 100th best-of-five-sets match on clay. He has a 98-2 win-loss record.

With rainclouds rolling in, Nadal seemed keen to get his third-round match over as quickly as possible and the No. 4 seed took 90 minutes to win 6-0, 6-1, 6-0.

"I don't know if it was perfection," said Nadal, who turns 31 on Saturday. "I went on court thinking it was going to be a tough match ... I believe I played the best match since a while."

Women's champ advances

Defending women's champion Garbine Muguruza advanced to the fourth round by beating Yulia Putintseva 7-5, 6-2.

The fourth-seeded Spaniard broke her opponent's serve three times in the second set.

Muguruza will next face 13th-seeded Kristina Mladenovic of France, who defeated American Shelby Rogers 7-5, 4-6, 8-6.

Venus schools youngster

Venus Williams reached the fourth round by beating an opponent who is 15 years younger than she is.

Williams, who turns 37 this month, did not get much of a test during a 6-3, 6-1 victory over 60th-ranked Elise Mertens of Belgium that lasted just over an hour at Court Philippe Chatrier.

The 21-year-old Mertens was playing in only her second Grand Slam tournament.

Williams is a seven-time major champion and was the runner-up at Roland Garros in 2002.
