The world No. 1 and three-time Grand Slam champion lags behind her contemporaries in endorsements despite standing atop her sport.

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.

American Madison Keys upset top-ranked Aryna Sabalenka 6-3, 2-6, 7-5 to win the 2025 Australian Open. This win gives Keys her first ever Grand Slam title at the age of 29.

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.
