Osaka’s Australian Open title defence over

Defending champion Naomi Osaka is out of the Australian Open after American opponent Amanda Anisimova survived two match points before clinching a memorable third-round victory.

However, Osaka says she feels "proud" of her approach and performance, despite the defeat that ender her campaign to retain her Australian Open title.

"I fought for every point. I can't be sad about that. You know, I'm not God. I can't win every match,"

she said.

"Today, of course there were things I felt I could improve on, but even with that, I had two match points, and I think that's something that I can be proud of myself for."

"I think this for me is the biggest step, even though I lost. I think I was really focused throughout the entire match, and I didn't have a dip. So that's really good."

Japan's 24-year-old Osaka was beaten by unseeded American Amanda Anisimova, who had lost her nine previous matches against top-20 opponents.

Osaka was seeded 13th after taking a four-month break at the end of last season, during which she revealed she had been suffering from depression.

The two-time champion, who also won the 2019 title at Melbourne Park, had also breezed through her opening two matches but faced a different proposition in Anisimova.

The American announced her arrival as a potential star when she reached the 2019 French Open semi-finals aged 17.

But the death of her father and coach Konstantin shortly before the US Open later that year understandably had a debilitating effect on her career.

Osaka is set to drop outside of the world's top 80 after being unable to defend a host of ranking points at the Australian Open. (BBC Sport)
