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. Open back in 2017,

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.
