INDIAN WELLS, Calif. - Eugenie Bouchard of Westmount, Que., defeated CoCo Vandeweghe 6-3, 6-2 to reach the fourth round of the BNP Paribas Open.

The sixth-seeded Canadian faced the only break point on her serve of the match in the last game, but Vandeweghe netted a forehand. Bouchard hit a forehand winner on her second match point. Vandeweghe had 24 unforced errors in the third-round match, the farthest the American has gotten at Indian Wells in four tries.

"I felt very solid," Bouchard said. "That's important against a player who can have big weapons. She had some great serves and some great forehands. I was going to try to neutralize that and take my chances when I had them."

Bouchard had plenty of support in the crowd from the many Canadians who spend the winter in the desert. They waved red and white Maple Leaf flags in what seemed like a home match for Bouchard.

In late women's action, Maria Sharapova beat Victoria Azarenka in a match between former No. 1 players.

The second-seeded Sharapova posted a 6-4, 6-3 victory to reach the fourth round. She won this tournament in 2006 and 2013 and lost to Azarenka in the 2012 final.

Sharapova's next opponent will be defending champion Flavia Pennetta. The 15th-seeded Italian defeated 21st-seeded Australian Samantha Stosur 6-4, 6-2.

Former Indian Wells champion and No. 4 seed Caroline Wozniacki lost 6-4, 6-4 to 31st-seeded Swiss Belinda Bencic. Wozniacki titled here in 2011 and was a runner-up twice.

Bencic, 18, failed to win a game off Wozniacki last year in Istanbul.

The teenager will face 2010 Indians Wells champion Jelena Jankovic in the fourth round. The 18th-seeded Serbian rallied to beat 16th-seeded American Madison Keys 5-7, 6-4, 6-3.

No. 5 seed Ana Ivanovic of Serbia, the 2008 Indian Wells winner, was beaten 6-2, 5-7, 6-2 by 25th-seeded Frenchwoman Caroline Garcia.

Garcia will next play 24th-seeded German Sabine Lisicki, who beat 11th-seeded Italian Sara Errani a 6-4, 6-2.

In night action on the men's side, top-seeded Novak Djokovic and fourth-seeded Andy Murray were third-round winners.

Djokovic managed his way past Albert Ramos-Vinolas 7-5, 6-3, while Murray held off 26th-seeded German Philipp Kohlschreiber 6-1, 3-6, 6-1 in a topsy-turvy affair on the hardcourts at the Indian Wells Tennis Garden.

The reigning titlist Djokovic is a three-time Indian Wells champion and former runner-up. He beat Roger Federer in last year's marquee finale.

Murray, meanwhile, is just two wins from surpassing Tim Henman's haul of 496 career match victories, which will make him Britain's most successful player in the Open Era in terms of matches won. He also needs just four more triumphs to join the 500 wins club.

The Australian Open runner-up Murray lost to the great Rafael Nadal in the 2009 Indian Wells finale.

Up next for the two-time Grand Slam champion from Scotland will be Frenchman Adrian Mannarino, who upended 14th-seeded struggling Latvian Ernests Gulbis 6-4, 6-4.

Kei Nishikori, the No. 5 seed, dropped the first set of his third-round match to Fernando Verdasco before rallying for a 6-7 (6-8), 6-1, 6-4 win. The 12th- seeded Feliciano Lopez beat Pablo Cuevas 6-2, 4-6, 6-3.

In an upset, 32nd-seeded Bernard Tomic fought past eighth-seeded David Ferrer 7-5, 6-4.

American John Isner got past 16th-seeded Kevin Anderson 7-6 (8-6), 6-2 and Thanasi Kokkinakis defeated Juan Monaco 6-2, 5-7, 7-6 (7-5).
