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.

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.
