Defending champion, Naomi Osaka has been knocked out of the Australian Open after Amanda Anisimova stunned her on Friday January 21, handed her a defeat.
The Japanese four-time Grand Slam champion, seeded 13, won the first set on Margaret Court Arena but Amanda, a 20-year-old American ranked 60th in the world beat Naomi 4-6, 6-3, 7-6 (5) F
“I’m speechless, I can’t stop smiling,” said the 20-year-old, who is undefeated this year after winning a lead-up tournament in Melbourne.

“I knew I had to be playing sharp if I wanted to give myself a chance. Naomi is always going to be playing well, she is an absolute champion.
“So I really had to step up my game and try to be aggressive. That’s what I started doing in the second set and so grateful I was able to do this well today and get the win. It means a lot.”
It’s the fourth time Osaka has been unable to defend a major title, and the 11th time in a Grand Slam she has been knocked out in the third round, including last year’s U.S. Open.
