The 23-year-old, fresh from her maiden Grand Slam triumph at the French Open, has not dropped a set all week and an 11th successive victory will see her displace Japan's Naomi Osaka in top spot and emulate Evonne Goolagong's feat from 1976. Barty sent down 11 aces and fired 24 winners on Saturday to dispatch world number 51 Barbora Strycova from the Czech Republic 6-4 6-4. "I have to try and do what I can do and that is prepare and do as best that I can tomorrow and try and play a good tennis match and if I win, it's a bonus," said Barty, who is seeking her sixth WTA tour title at an event where she was runner-up to Petra Kvitova in 2017.
