"It's a great feeling to come back and defend a title," Muguruza said in a courtside interview. "It's never easy."
Meanwhile, Azarenka received treatment on her leg during a medical time-out between sets, but she apparently failed to resume due to pain.
Azarenka last won against Muguruza in the round of 16 at the Miami Open in April 2016, when she went on to win the title in her most recent final before Sunday.
