and it's all over! Australia have thrown it away towards the end, full on the off stump and Boucher slogs it over midwicket for a boundary, the crowd goes wild, and the South Africans - on the field and in the dug out - are ecstatic.
South Africa were in deep trouble at one stage - they were 83 for 5 - but Boucher and Morkel sparked a revival with a stand of 58 for the sixth wicket. Morkel fell for a superb 19-ball 37 but Boucher stayed till the end, repeating his feat in that famous chase of 434, to guide his team to a thrilling four-wicket win.

Timely wicket for Australia, but the end of a superb contribution from Morkel
