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.

Aryna Sabalenka saw her two-year reign at the Australian Open end after losing to Madison Keys in the final – and she didn’t take it well.
