In the other match in Group A, the unbeaten Russians booked their place in the quarter-finals by defeating Belarus 71-65.

Australia are widely regarded as the only team capable of preventing the US from claiming their fourth Olympic title.

But Australia coach Jan Stirling denied the competition was a two-horse race, saying: "Neither I or (American coach) Anne Donovan feel like that. We still have a lot of hard yards to do."
