Maria Sharapova has made it two wins out of two following her return from a 15-month doping ban by defeating fellow Russian Makarova 7-5 6-1.
The five-time Grand Slam winner dominated Makarova, ranked 43 in the world, wrapping up the victory in just one hour, 20 minutes.
Sharapova was powerful on serve, as she had been in Wednesday’s win over Italy’s Roberta Vinci, but struggled at times with her return.
Once she had claimed the first set with a late break of serve, she powered through the second, breaking twice before wrapping up the match with an ace.
“Practice and playing are so different and you can only prepare the best you can,” Sharapova said.
“The reaction and anticipation you need are so hard to replicate in training and these are the things I need.”
In the last eight, the 30-year-old faces Estonian qualifier Anett Kontaveit, who was a 2-6 7-6 (7-1) 6-1 victor over Spanish fifth seed Garbine Muguruza.
