Eugenie Bouchard raced into the French Open quarter-finals by beating eighth-seeded Angelique Kerber of Germany 6-1, 6-2 in 52 minutes on Sunday.

The 18th-seeded Canadian wasted no time, opening up a 5-0 lead in just 16 minutes. The Montreal native, who reached the Australian Open semifinals this year, next plays either No. 14-seeded Carla Suarez Navarro of Spain or the unseeded Ajla Tomljanovic. They were playing later Sunday.

"I just felt good out there, I executed my game plan really well, so I'm happy with that," said Bouchard. "There are always things to improve, and I'm just going to focus on that tomorrow and try to do even better my next match."

Federer falls to Gulbis in 5 sets

Roger Federer's streak of nine consecutive quarterfinals at the French Open ended Sunday with a 6-7 (5), 7-6 (3), 6-2, 4-6, 6-3 fourth-round loss to 18th-seeded Ernests Gulbis of Latvia.

It was 17-time Grand Slam champion Federer's earliest exit at Roland Garros since 2004, when he was beaten in the third round by three-time champion Gustavo Kuerten.

After that, though, Federer made at least the quarter-finals at a record 36 consecutive Grand Slam tournaments, a streak that ended with a second-round loss at Wimbledon last year.

Now the 32-year-old Federer has bowed out before the quarter-finals at three of the last four majors, including a fourth-round loss at the U.S. Open in September.

"I think it was the biggest, probably, win of my career," said Gulbis, who most certainly could have dispensed with the word "probably."

Addressing the spectators during an on-court interview, Gulbis said: "I'm sorry I had to win. I know all of you like Roger."

Next for Gulbis will be a match against No. 6 Tomas Berdych of the Czech Republic, who eliminated No. 10 John Isner of the United States 6-4, 6-4, 6-4.

Kerber, a quarterfinalist at Roland Garros two years ago, made a string of unforced errors and Bouchard broke for a 2-1 lead in the second set when Kerber returned long from the back of the court.

Trailing 5-2, Kerber played with the strings of her racket as she hunched forward on her chair, her head bowed. Bouchard, by contrast, sat upright, taking a few deep breaths to compose herself before serving out the match. She clinched victory on her first match point when Kerber — a two-time Grand Slam semifinalist — made another unforced error, this time as her wild forehand sailed out.

"I'm confident and I really believe in my skills. I believe I can play with the best girls out there," Bouchard said. "She's top 10, so I respect her. She can play some really good tennis. I was really mentally prepared for anything, for a battle."

With the top three women's seeded players out, Maria Sharapova remains the favourite to win the tournament for the second time. The seventh-seeded Russian later played Samantha Stosur.

Bouchard`s dominant victory over Kerber stretched her winning streak to nine straight matches — the longest of her career. And it lifted her career record against top 10 opponents to 5-10.

Her victims this season have also included No.10 Sara Errani at Indian Wells in March and No.8 Jelen Jankovic last April in Charleston.

Men's eighth seed Milos Raonic of Thornhill, Ont., was attempting to join Bouchard in the last eight as he faced Spain's Marcel Granollers. Raonic is the first Canadian man to play in the fourth round at Roland Garros.

Andy Murray to 4th round

Andy Murray found his second wind to finally get the better of Philipp Kohlschreiber of Germany, needing 40 minutes to complete a 3-6, 6-3, 6-3, 4-6, 12-10 win and reach the French Open fourth round on Sunday.

The match between Wimbledon champion Murray and the 28th-seeded Kohlschreiber was suspended because of fading light Saturday.

"I was cramping yesterday. My muscles were obviously fatigued," Murray said. "I actually woke up [feeling] okay … the nice thing about this surface, compared with the hard court, is when you have a tough match on the hard courts you wake up the next day and your hips are sore, your knees are sore."

Kohlschreiber missed a chance to break Murray in the 19th game of the decider.

"He came up with some great shots when he was behind in games today," Murray said. "I thought both of us served a little bit better. It was a good finish to the match."

Murray, a two-time Grand Slam champion, crouched down and clenched both fists after hitting a two-handed backhand winner on Kohlschreiber's second serve with the score at 15-40 in the 22nd game.

Murray, the 2012 U.S. Open champion, made light of a disturbed night's sleep of barely five hours.

"I was kind of ready to play at 4 or 5 in the morning," he said. "When you know you have to come back and it's 7-all the next day and every single point counts, basically you need to get off to a big start. You're obviously going to be a bit anxious."

He will get a longer rest before playing Monday against No. 24 Fernando Verdasco of Spain, who easily beat 12th-seeded Frenchman Richard Gasquet 6-3, 6-2, 6-3. Murray leads Verdasco 9-1 in their career head-to-heads but they have never met on clay.

In men's fourth-round action later Sunday, second-seeded Novak Djokovic was playing No. 13-seeded Jo-Wilfried Tsonga; fourth-seeded Roger Federer took on Ernests Gulbis; and sixth-seeded Tomas Berdych faced No. 10-seeded John Isner.

In the men's fourth round, Tomas Berdych defeated 10th-seeded John Isner 6-4, 6-4, 6-4. The sixth-seeded Czech next faces either 17-time Grand Slam champion Roger Federer, seeded fourth, or No. 18 Ernests Gulbis of Latvia. They were playing their match later Sunday.
