INDIAN WELLS, Calif. - Women's singles quarterfinal play in the BNP Paribas Open concludes Thursday with two matches on the Indian Wells Tennis Garden's Stadium Court, while the men's singles quarterfinals will begin with two matches.
The day's play is set to begin at 11 a.m. with the top-seeded woman, China's Li Na, facing 12th-seeded Dominika Cibulkova of Slovakia. Li has won all five of her matches against Cibulkova, including a 7-6 (3), 6-0 victory in the final of this year's Australian Open.
The other women's quarterfinal will pit the lone remaining American in the women's singles draw, 17th-seeded Sloane Stephens, against 20th-seeded Flavia Pennetta of Italy. Pennetta has won two of her previous three matches against Stephens, but Stephens was the winner in their most recent meeting, last May in Rome. The match will be the third of the day on the Stadium Court and won't begin until 3 p.m. at the earliest.
Men's quarterfinal play won't begin until 1 p.m. at the earliest when 10th-seeded Canadian Milos Raonic faces 28th-seeded Alexandr Dolgopolov of Ukraine.
Both players have victories over big-name players in the tournament. Dolgopolov Monday upset the tournament's top seed, Spain's Rafael Nadal, while Raonic ousted Wimbledon champion Andy Murray of Britain on Wednesday.
The fifth-seeded Murray broke Raonic's serve in the third game of the third set to take a 2-1 lead, but Raonic won the next four games. Murray held serve in the eighth game of the set, but Raonic then held serve to close out the 4-6, 7-5, 6-3 victory.
``I was just really disappointed with how the last 15 minutes of the match went,'' Murray said. ``That was really, really poor.''
The other men's quarterfinal matches seventh-seeded Roger Federer and the 17th-seeded South African Kevin Anderson, who upset Federer's Swiss countryman, third-seeded Stanislas Wawrinka, 7-6 (1), 4-6, 6-1 on Wednesday. Anderson broke Wawrinka's serve in the first game of the third set and again four games later.
``I felt I was tired mentally, but that's not the problem,'' Wawrinka said after losing for the first time in 2014 following 13 victories. ``I should just accept that and be positive. I think I was negative on all the match. I was complaining a lot about my serve, about the way I was playing and with that, I don't deserve to win matches.
``I should have been more positive with myself, just trying to find (a) solution.''
In other matches Wednesday, the highest remaining seed, second-seeded Novak Djokovic of Serbia, defeated 24th-seeded Marin Cilic of Croatia, 1-6, 6- 2, 6-3, in a late-night match, and the last American remaining in the men's draw, 12th-seeded John Isner, defeated 30th-seeded Fernando Verdasco of Spain, 7-6 (3), 3-6, 6-3.
``I just accepted the fact that he came out of the blocks better than I did,'' Djokovic said after improving to 8-0 against Cilic. ``He was very aggressive, not missing at all, serving incredibly fast and accurate. I couldn't do much really, I was forced to back up.
``I believed that I could come back. The second set was a whole new story. I reset myself and told myself it was the start of the match. I forgot about the first set and the second and third set went really well. It was the intensity I want to have and I hope to keep it up.''
In women's quarterfinal singles play Wednesday, second-seeded Agnieszka Radwanska of Poland defeated seventh-seeded Jelena Jankovic of Serbia, 7-5, 2- 6, 6-4, and sixth-seeded Simona Halep of Romania defeated Australian qualifier Casey Dellacqua, 6-2, 6-2 in 61 minutes.
Radwanska will face Jankovic in a semifinal Friday. Radwanska has won three of their five matches, but Halep triumphed in their most recent meeting in January.
