Coco Gauff repeated her Wimbledon victory over Venus Williams, winning 7-6 (7-5) 6-3 under the roof on Margaret Court Arena on the opening day of the Australian Open.
The 15-year-old's success in the first round at the All England Club last summer catapulted her to global stardom.
With Gauff now a top 100 player - and Venus having been a doubt for the tournament with a hip injury - this result came as less of a shock.
The young American showed maturity well beyond her years to battle through after nerves kicked in during the first set.
Gauff led 5-3 and had three set points, while a 5-2 lead in the tie-break also disappeared, but a missed backhand volley from Venus at 5-6 helped her young opponent over the line in the opener.
There were no wobbles in the second, and Gauff said: "That was really difficult, she played really well. I was really nervous for today's match. I was a bit shocked, I'm sure everybody was shocked, when they saw that draw, but I'm really glad to get through it."
Venus praised Gauff, saying: "I think honestly she played really well, consistently, both matches. She clearly wants it, works very hard, is extremely mature for her age. I think the sky's the limit for her."
