Azarenka will face Romina Oprandi of Switzerland, while Sharapova will play Angelique Kerber of Germany. Kerber beat former No. 1 Caroline Wozniacki 6-1, 2-6, 6-4.
"I played really well in the beginning and got a little tense in the second set," Sharapova said. "But I felt like I really needed that challenge."
Azarenka looks to rebound from her trip last week to Tokyo, when she withdrew from the tournament after a bout of dizziness in the third round.
Li Na beat Shuai Peng 4-6, 6-2, 7-6 (3) in an all-Chinese clash. Li will face third-ranked Agnieszka Radwanska.
