Johannesburg, Feb. 23 : The key to Australia defeating South Africa will be team skipper Ricky Ponting, who averages more than 50 per innings in Tests.
If the captain grabs the Proteas by the scruff of the neck and overshadows rival skipper Graeme Smith to make the series his own, not only will Australia''s chances of retaining the world No. 1 ranking go through the roof, but Ponting will go close to overtaking Steve Waugh in fourth place on the list of Test run-scorers," says in an article for the Sydney Morning Herald.
