Australian Open: 15-Year-Old Coco Gauff Knocks Out Defending Champion Naomi Osaka [Video]

American teenager, Coco Gauff has knocked out the defending champion, Naomi Osaka, in straight sets to reach the fourth round of the Australian Open.

The 15-year-old excelled in the Rod Laver Arena and won 6-3 6-4.

Osaka won the pair’s only previous meeting at last year’s US Open, but it was Gauff who was victorious in Melbourne, winning in 67 minutes.

“I don’t know where that came from,” the American said after the match. “Honestly, like, what is my life?”

“Two years ago I lost in the first round in juniors and now I’m here,” Gauff added.

“I was telling myself one point at a time and keep fighting. You never know what happens on this court.”

Gauff will play either China’s Zhang Shaui or American Sofia Kenin in the fourth round.
