MELBOURNE - Fifth seed Aryna Sabalenka of Belarus fought back from a set down to defeat reigning Wimbledon champion Elena Rybakina to win the Australian Open women's singles title on Saturday.

In a nerve-jangling final, Sabalenka overcame the gallant 22nd seed 4-6, 6-3, 6-4 to record her first Grand Slam triumph.

It capped a spectacular tournament for Sabalenka, who hadn't dropped a set before the final, while Rybakina of Kazakhstan was unable to add a Grand Slam title to last year's Wimbledon crown.
