Azarenka is hoping to rebound from last week in Tokyo, where she withdrew after feeling dizzy in the third round.
Azarenka has won four times this year, including the Australian Open. Sharapova won her first Grand Slam title in four years at the French.
Other first-round winners included Sorana Cirstea of Romania and Carla Suarez Navarro of Spain, who upset fourth-seeded Petra Kvitova of the Czech Republic.
