Canberra: Australia cruised to a 73-run victory over South Africa in their third one-day international on Wednesday on the back of big-hitting innings by Aaron Finch and Steve Smith. Opener Finch cracked 109 off 127 balls and Smith hit a swashbuckling unbeaten 73 off 55 balls as Australia amassed a formidable 329 for five off their 50 overs in Canberra.

The Proteas were always up against it and were dismissed for 256 in the 45th over, with last man Imran Tahir unable to bat because of a knee he injured while fielding. The Australians now lead the five-match series 2-1 ahead of the final games in Melbourne on Friday and Sydney on Sunday.
