Sabalenka and Gauff will meet in the semi-finals should they win their respective matches in the last eight. Belarus's Sabalenka was out on a roasting centre court for only 62 minutes before registering an 18th consecutive win at Melbourne Park.

"I'm super happy to get through this difficult match in straight sets," said Sabalenka, who faces Anastasia Pavlyuchenkova next. The Russian 27th seed beat ailing Croatian 18th seed Donna Vekic 7-6 (7/0), 6-0.
