Defending champion Naomi Osaka knocked out – day five at the Australian Open

Amanda Anisimova claimed the biggest result of the Australian Open so far as she knocked out defending champion Naomi Osaka in the third round.

The young American won a big-hitting battle on a deciding tie-break and will next face world number one Ashleigh Barty, who eased to victory over Camila Giorgi.

Rafael Nadal dropped his first set of the tournament but recovered to beat Karen Khachanov while Matteo Berrettini edged a five-set struggle against 18-year-old Spaniard Carlos Alcaraz.
