PARIS — After a pair of five-setters, Andy Murray made it through to the fourth round of the French Open in only three.
The second-seeded Murray, who spent more than seven hours on court in the first two rounds, beat Ivo Karlovic 6-1, 6-4, 7-6 (3) Friday.
Murray was in control from the start, quickly jumping to a 5-0 lead. The big-serving, 6-foot-11 (2.11-meter) Karlovic wound up with only 14 aces after hitting a tournament-high 72 aces through the opening two rounds.
Milos Raonic also advanced, overcoming an aching hip to beat 133rd-ranked "lucky loser" Andrej Martin of Slovakia 7-6 (4), 6-2, 6-3.
Raonic said he will have tests on the aching left hip that led him to ask for painkillers during his match on Court 1.
"I just tried to fight through," the eighth-seeded Canadian said. "I’m happy with the fact that I was able to continue."
In the women’s draw, Garbine Muguruza, Simona Halep and Samantha Stosur all made it through to the fourth round. But two-time Wimbledon champion Petra Kvitova lost to Shelby Rogers 6-0, 6-7 (3), 6-0.
Rogers, an American ranked 108th, is now into the fourth round at a Grand Slam tournament for the first time.
The fourth-seeded Muguzura beat Yanina Wickmayer of Belgium 6-3, 6-0, while Halep had a tougher time against Japanese teen Naomi Osaka. Halep won 4-6, 6-2, 6-3 in what was the 18-year-old Osaka’s first match against a top-10 player.
Playing in only her second major tournament, Osaka won the first set but then struggled against the 2014 French Open runner-up from Romania.
"I’m just going to take this as like a learning lesson," Osaka said. "Maybe I managed to like worry her for a second there."
Halep broke Osaka to love in her first service game of the second set and converted the first of two break points at 5-2 to level at one-set each. In the third, Halep again broke Osaka to love for a 5-3 lead and then served out the victory.
Muguruza, who was the runner-up at Wimbledon last year and reached the quarterfinals at the French Open in 2014 and 2015, lost one service game to Wickmayer in the first set but otherwise had no real difficulties.
Wickmayer had no break points in the second set and saved none of the six she faced, while Muguruza had an impressive ratio of 19 winners to only 11 unforced errors.
