Barty said: “I think overall I felt pretty good. Ana did an exceptional job in making me play to a very high standard. I knew right from the first point I was going to have to be ready tonight and switched on straightaway. That was really nice to have that challenge.” Petra Kvitova won a high-quality contest to end the day, beating 40-year-old Venus Williams 7-6 (6) 7-5, while sixth seed Garbine Muguruza thumped Alison Van Uytvanck 6-2 6-0. Australian Open champion Sofia Kenin had just won the first set 7-5 against Camila Giorgi when the Italian retired. Osaka was playing her first match since lifting her third slam title in New York last September and eased past Alize Cornet 6-2 6-2 at the Gippsland Trophy.
