American teenager Coco Gauff fulfilled the potential she has long promised by landing her first Grand Slam title with a fightback win over Aryna Sabalenka in the US Open final.
Gauff, seeded sixth, started slowly in front of an expectant home crowd but grew in confidence to wear down second seed Sabalenka in New York.
Gauff, 19, clinched a 2-6 6-3 6-2 win on a delirious Arthur Ashe Stadium.
Australian Open champion Sabalenka must wait for a second major title.
The 25-year-old Belarusian can at least console herself with the knowledge she will become the world number one for the first time.
