The newlywed Keys, whose husband and coach is former American tennis player Bjorn Fratangelo, said after some much needed sleep, they'll be "back to work on Monday" to prepare for "lots of tournaments" including the BNP Paribas Open at Indian Wells and the Miami Open back to back in March.

MELBOURNE, Australia — Madison Keys beat Aryna Sabalenka 6-3, 2-6, 7-5 in the Australian Open final at Melbourne Park Saturday.

Madison Keys of the United States has upset two-time defending champion Aryna Sabalenka of Belarus 6-3, 2-6, 7-5 in the Australian Open final.

MELBOURNE, Australia — When Madison Keys stepped into Rod Laver Arena at 7:37 p.m. on Saturday night ahead of the Australian Open final, she strode right past the Daphne Akhurst Memorial Cup, the trophy that goes to the women’s champion and was placed on a pedestal near the entrance to the court.

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).

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.

Keys, ranked 14th and seeded 19th, prevented Sabalenka from earning what would have been her third women's trophy in a row at the Australian Open — something last accomplished by Martina Hingis from 1997-99 — and her fourth major title overall.

American Madison Keys dethroned Aryna Sabalenka to become the oldest first-time winner of the women’s singles title at the Australian Open.
