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)

Sabelenka will face 19th seed Madison Keys for the Daphne Akhurst Memorial Cup, with the American having produced one of the shocks of the tournament to beat Iga Swiatek in a final-set tiebreak to secure a dramatic 5-7, 6-1, 7-6 (10-8) victory.
