The Madison Keys who will play two-time defending champion Aryna Sabalenka for the title at the Australian Open on Saturday night is not the same Madison Keys who was the runner-up at the U.S.

With women’s tennis on the verge of an epic showdown between its top two players with the Australian Open title on the line, Keys, the 29-year-old American, crashed the party. She stormed back against Iga Swiatek to win their semifinal 5-7, 6-1, 7-6 (10-8).

Sabalenka beat good friend Paula Badosa of Spain earlier Thursday, 6-4, 6-2. Sabalenka, a 26-year-old from Belarus, can become the first woman since 1999 to win three consecutive Australian Open singles crowns. "If she plays like this," the 11th-seeded Badosa said, "I mean, we can already give her the trophy."
