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

The world No. 1 is seeking a third Australian Open title in a row. This is what makes her the best player in the world.

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.
