Australia’s Ariarne Titmus has won the silver medal in the women’s 800-metres freestyle at the Tokyo Olympics.

Titmus’ second place in Saturday’s final won by American Katie Ledecky gives the Australian a fourth medal of the Games.

It follows her wins in the 200m and 400m freestyles and a bronze in the 4x200m freestyle relay.

The Australian could also add another in the 4×100 medley relay final on Sunday.

In the 800m freestyle final, Titmus and the rest of the field were unable to counter Ledecky, who won the event for a third consecutive Olympics to claim a seventh career gold medal.

The American won in eight minutes 12.57 seconds from Titmus (8:13.83) and Italian Simona Quadarella (8:18.35).

Australia’s Kiah Melverton (8:22.25) finished sixth.
