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)

Madison Keys has a chance for tennis immortality again — and it took everything she had to get there. The 29-year-old American stunned No. 2 seed Iga Swiatek at the Australian Open with a dizzying display of power and shot-making to advance to the Grand Slam final, taking the thrilling third set in a tiebreaker.
