Swiatek will face No. 19 Madison Keys of the U.S. on Thursday night for a berth in the final. The other women’s semifinal is No. 1 Aryna Sabalenka, the two-time defending champion, against her good friend, No. 11 Paula Badosa.

No. 19 seed Madison Keys scored the big upset on Day 9 of the Australian Open, defeating No. 6 Elena Rybakina 6-3, 1-6, 6-3 at Margaret Court Arena to advance to the tournament quarterfinals.

A few hours ago Iga Swiatek dropped just three games as she breezed past Emma Navarro to reach the Australian Open semi-finals and continue her bid for a maiden Melbourne title. Five-time major winner Swiatek was ruthless in a 6-1 6-2 victory over eighth seed Navarro.
