The last two Canadian women exited the BNP Paribas Open on Tuesday, with Eugenie Bouchard and Aleksandra Wozniak both suffering fourth-round defeats.

Two forehand errors spelled the end for Montreal's Bouchard, who lost to sixth-seed Simona Halep of Romania 6-2, 1-6, 6-4.

Australian Open winner and top seed Li Na defeated Wozniak of Blainville, Que., 6-1, 6-4, with the Canadian saving ten match points. Li double-faulted on four of the potential match-winners in a dramatic concluding game.

Wozniak, ranked 241 after missing play over the past 18 months due to a shoulder injury, went down fighting in just over 90 minutes as a return sailed long over the baseline.

"It was a good week for me, I'm making progress with my game and I'm feeling very positive," said Wozniak. "I'll now just keep working and trying to improve."

Wozniak lost the opening set in 32 minutes but pinned Li down with a 3-0 lead in the second before the Chinese player fought back.

"That was a crazy final game," said Wozniak. "In the first set she had me on my heels but in the second I began to adapt. I just wish that I could have broken in that final game for 5-all and played on."

The Canadian will prepare for qualifying rounds set for early next week in Miami after using up her final protected tournament entry for this event.

"I have a wild card into Miami so that's another chance," said Wozniak. "I'm glad my tennis is back to this level."

Milos Raonic, Thornhill, Ont., will bid for a quarter-final berth on Wednesday when he plays fifth-seeded Wimbledon winner Andy Murray.

The 20-year-old Bouchard, making her debut in the main draw at the Tennis Garden after losing in the 2013 qualifying rounds, set up a match point for Halep with a forehand wide and drove another one out a point later to end the one-hour 37-minute battle.

Bouchard, ranked a career-high 19 after her Australian Open semi-final, fired seven aces but was weighed down by six double-faults.

"I didn't start so great, but I served better in the second set," said Bouchard. "I had a few easy holds but some tough battles as well. I could have done with a few more first serves. I tried to go for my shots in the rallies. but I didn't take my chances."

Bouchard was stunned in the opening set as Halep raced away to a 5-0 lead before Bouchard could make an impression in what turned into a routine 30-minute effort.

Bouchard rallied in the second as her form returned after the slow start, levelling the sets at one each with two breaks of her seeded opponent,

Bouchard then lost a third-set break as Halep squared at 4-all. Halep put her opponent under pressure on serve in the tenth game, with Bouchard's pair of forehand errors sending her to defeat.

"She was very solid, exactly what I expected," said Bouchard, who will now head to her training base in Florida to prepare for the Miami tournament which starts next week. "She put the pressure on me today, she's won a lot of titles so she knows how to battle.

"Maybe I don't deserve it, but I'll take a day off and get back to practise. Florida is like my second home and I'm looking forward to a good tournament.

Djokovic advances to quarters

Novak Djokovic defeated Alejandro Gonzalez 6-1, 3-6, 6-1 to end the Colombian's surprising run to the third round.

Djokovic, a two-time champion at Indian Wells, earned the only two breaks of the third set, including a seven-deuce game that he closed out with a clever backhand drop volley.

Gonzalez had never won an ATP Tour-level match in six tries before Indian Wells. He won third-set tiebreakers in his first two matches here before keeping the world's second-ranked man on the court for just over 1 1/2 hours.

"It took me a little bit to get used to it," Djokovic said. "You've got new faces and new players who are able to challenge the top guys, and this is good for the sport. It also makes us work harder and improve trying to get our game to a high level because the guys are coming up."

Djokovic had 28 winners to 11 for Gonzalez, who also had 23 unforced errors.

"I just had a big loss of concentration and allowed him to win the second set for no reason," Djokovic said. "Bounced back better in the third, but I obviously cannot allow myself to have these particular concentration lapses in the match at this level."

Djokovic next plays Marin Cilic of Croatia, who beat Tommy Robredo 6-4, 6-3.

Jankovic routs Wozniacki 

Jelena Jankovic routed Caroline Wozniacki 6-3, 6-1 to reach the quarterfinals, winning a matchup of former tournament champions and No. 1-ranked players.

Jankovic next plays either second-seeded Agnieszka Radwanska or 22nd-seeded Alize Cornet, who met late in a fourth-round match.

Top-seeded Li Na played Aleksandra Wozniak of Canada, and American John Isner took on Yen-Hsun Lu of Taipei in night matches.

Jankovic made the quarterfinals for the first time since winning the Indian Wells title in 2010, when she beat Wozniacki. The Dane won the title in 2011 and lost to Maria Sharapova in last year's final.

But she offered little resistance against Jankovic, who raced to 5-0 in the second set before Wozniacki held at 40-love to avoid being shut out in front of her fiance, golfer Rory McIlroy.

"I kind of found my way, found my rhythm, and I was striking the ball very well out there and took control of the points," Jankovic said. "I just did not let her play what she plays. That was very important."

Jankovic was the world's top-ranked player in 2008. Wozniacki reached the top spot in 2010; she's now No. 12. Jankovic, ranked eighth, was the first top-10 player Wozniacki has faced so far this year.

Jankovic ended a five-match skid against Wozniacki, with the Serb having recovered from a back problem that occurred in her match two nights earlier. Jankovic didn't hit on Monday and felt too stiff to put her shoes on.

"I went on court today not knowing how I was going to feel, if I was going to be limited with my movement or if I was going to play my game," she said. "But I did and I was surprised."

American Lauren Davis withdrew from her match against qualifier Casey Dellacqua of Australia because of a gastrointestinal illness. Dellacqua advanced to the quarters against No. 6 seed Simona Halep of Romania, who beat Eugenie Bouchard of Canada, 6-2, 1-6, 6-4.

In other men's matches, Fernando Verdasco of Spain beat No. 8 seed Richard Gasquet, 7-6 (5), 6-1; and Roberto Bautista Agut of Spain beat Jarkko Nieminen of Finland 6-2, 4-6, 7-6 (6).
