Defending champion Naomi Osaka is out of the Australian Open

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.

Japan's Osaka was beaten 4-6 6-3 7-6 (10-5) at Melbourne Park.

Unseeded Anisimova will play Australian top seed, Ashleigh Barty, in the last 16.

Barty has still not dropped a set this week after a 6-2 6-3 victory over Italy's Camila Giorgi.

The 25-year-old Queenslander is carrying the hopes of a nation desperate to see a home Australian Open champion for the first time since Chris O'Neil in 1978.
