Australian Open champion Victoria Azarenka swept aside Polish Urszula Radwanska 6-3 6-1 in a match lasting just under 90 minutes to advance into the quarter finals of the BNP Paribas Open at Indian Wells.
Top seed Azarenka broke Radwanska's serve three times in the opening set and twice in the second.
Azarenka will next face either eighth-seeded Dane Caroline Wozniacki or Russian Nadia Petrova.
The 23-year-old Belarusian is on a 17-match winning streak, coming off titles at the Australian Open (d. Na Li) and Doha (d. Serena Williams). Last year, she defeated Maria Sharapova in the Indian Wells final.
