She advanced on her third match point – an ace – to next face the winner from US third seed Jessica Pegula and two-time Melbourne winner Victoria Azarenka.

“This will be my first semi-final here and I’m very happy about it,” Rybakina said. “I was nervous in the last game, but not as much as before the match.
