- Osaka defeated 4-6, 6-3, 7-6 (5) in dramatic tie-break
- Player held two match points at 4-5 in final set
Defending champion Naomi Osaka is out of the Australian Open after a third-round defeat by American Amanda Anisimova.
Osaka has returned to the sport this month after two breaks last season to protect her mental health, and had comfortably won her first two matches. But in 20-year-old Anisimova she came up against a player in red-hot form and, although Osaka did not play badly, she was beaten in a deciding first-to-10-points tie-break, losing 4-6, 6-3, 7-6 (5).
