serving Milos Raonic 6-7 (4), 6-2, 6-4 under the lights in the fourth round of the BNP Paribas Open Tuesday, extending his run of winning 35 of 37 matches since last year's US Open. Rafael Nadal didn't have as much trouble in sunny conditions, beating countryman Marcel Granollers 6-1, 6-4. It was similarly easy on the women's side for top-ranked Victoria Azarenka and No. 2-seeded Maria Sharapova, who won their matches in just more than an hour to reach the quarterfinals. Ana Ivanovic defeated Caroline Wozniacki 6-3, 6-2 in a matchup of former Indian Wells champions and former top-ranked players. Ivanovic served out the match with a 40-love game to complete her biggest win over a top player in months. Wozniacki's loss ensured she will drop out of the No. 4 spot in next week's rankings. Federer broke to open the second set and broke again in the seventh game to even the match. In the third, he broke Raonic to go up 4-3. Raonic held at love to get to 5-4 before Federer won four straight points to close out his 73rd consecutive win against a player outside the top-20. Nadal, ranked second in the world, has won his past 10 matches against fellow Spaniards, and 22 of his past 23 sets against them. Granollers, who has risen from 50th to 26th in the rankings over the past year, cracked a 132-mph serve during the match, but he couldn't overcome Nadal's quickness and touch. Nadal served out the match in a deuce game. Nadal plays No. 21 Alexandr Dolgopolov in the quarterfinals. Azarenka, a 6-3, 6-1 winner over Julia Goerges, moved on to play fifth-seeded Agnieszka Radwanska, who advanced when American wild card Jamie Hampton retired with cramping in the third set trailing 3-6, 6-4, 3-0. Sharapova beat Roberta Vinci 6-2, 6-1, and next plays Maria Kirilenko, who beat No. 30 Nadia Petrova 6-1, 5-7, 6-2. On the men's side, fifth-seeded David Ferrer lost for just the second time this year, 6-4, 6-3 to Denis Istomin of Uzbekistan. Istomin next plays No. 9 Juan Martin del Potro, who defeated Fernando Verdasco 6-2, 7-6 (6). David Nalbandian defeated Janko Tipsarevic 6-3, 3-6, 6-3, while Thomaz Bellucci advanced when Nikolay Davydenko withdrew. Other winners were Jo-Wilfried Tsonga; Marion Bartoli; Li Na; and Angelique Kerber, who beat American Christina McHale.
