Australian Open: 15-year-old Coco Gauff knocks out Osaka

Coco Gauff stunned Naomi Osaka to reach the fourth round of the Australian Open.
The 15-year-old Gauff has already made headlines around the world, but none of her achievements so far could compare to this as she took apart the defending champion in straight sets.
Gauff, who won just three games against Osaka when they met at the US Open last summer, was rock solid and took advantage of an error-strewn display from her opponent to win 6-3 6-4.
The American is the youngest player to beat a top-five ranked opponent since Jennifer Capriati toppled Gabriela Sabatini at the 1991 US Open.
“Two years ago I lost first round in juniors, and now I’m here. This is crazy,” said the teenager.
“I was just telling myself one point at a time and keep fighting because you never know what happens on this court.
“I’m on Rod Laver Arena, I can’t believe this.”
