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.
