World number one-ranked Victoria Azarenka and number two-ranked Maria Sharapova are both headed to the quarterfinals of the 2012 BNP Paribas Open in Indian Wells, Calif., both defeating their opponents in less than an hour. Also victorious was Serbia's Ana Ivanovic, a 6-3, 6-2 winner over former world number one Caroline Wozniacki.
Azarenka advances to face fifth-seeded Agnieszka Radwanska after Azarekna's 6-3, 6-1 win over Julia Goerges. Radwanska makes the quarterfinals after American wild card Jamie Hampton was forced to retire due to cramping. Azarenka has won all three meetings against Radwanska to date in 2012, with two of their matches going to three sets.
Sharapova, who lost to Azarenka in the finals of the 2012 Australian Open, defeated Italy's Roberta Vinci 6-2, 6-1, and next plays the number 20 seed, Russian Maria Kirilenko, a 6-1, 5-7, 6-2 winner over fellow Russian, Nadia Petrova.
Ivanovic lost her first two service games, but after being down four break points in the fifth game, she lost just six points on serve the rest of the way. Ivanovic advances to face France’s Marion Bartoli in the quarterfinals for a second straight year after Bartoli 's 6-1, 6-4 win over Lucie Safarova.
Also advancing to the quarterfinals in Indian Wells were German Angelique Kerber, a 6-3, 3-6, 7-6(4) winner over American Christina McHale in two hours and 33 min. Kerber will meet the number eight seed, China's Li Na, who advanced with a 6-1, 6-0 win over Czech Klara Zakopalova in just 56 min.
