With Australia loosing one day series 4-1 to South Africa they are no more at the top of the ladder. South Africa now take the top spot and they sure deserve it.
Its been a magical tour for South Africa, nobody would have bet that they would defeat Australia in both forms of the game. Australia's supremacy is dead and gone. I don't see them making a come back in the near future. It wont be long before they loose the top spot in the test ranking as well
