Aussies claim welcome win

Peter Siddle and Mitchell Johnson did the damage with the ball as the hosts added just two runs to their interval score of 289.

Johnson claimed four wickets for 118, while Siddle picked up three wickets for 56 as Australia gained some revenge for their recent Test series defeat to South Africa on home soil.

Having started the day at 178 for two, Hashim Amla (57) reached his half-century when he capitalised on a Johnson half-volley and drove him through the covers for four. But seven runs later he perished when attempting to flick Siddle through the leg side - his failure to keep the ball down proved his undoing as Phillip Hughes gathered a simple catch at short square-leg.

AB de Villiers was next to follow when Billy Bowden sent him on his way after being trapped leg before wicket by Andrew McDonald for three.

The batsman was not convinced, though, and asked for a referral, but his fate was confirmed by TV umpire Asad Rauf, who eliminated any doubt the ball was sliding down leg side.

The new ball, which was expected to be crucial on the final day, was taken as soon as it became available and Johnson almost struck with the first delivery when Jacques Kallis was trapped low on his pads and given out lbw by Bowden.

Kallis also opted to go upstairs, with Rauf deciding that the ball pitched outside the line and reversed the initial call by the on-field umpire. But Kallis only lasted until Johnson's next over when he tried to drive a fuller delivery and instead succeeded in playing on for 45 as South Africa slumped to 247 for five at lunch.

After the break JP Duminy was first to go when his attempts to fend off a Siddle bouncer saw the ball float easily to Ponting at second slip for 29, and Morne Morkel threw his wicket away cheaply with an attempted pull shot off Johnson that only flew high to Hughes at mid-on for two.

Wicketkeeper Mark Boucher was next to go, clean bowled by Ben Hilfenhaus, followed by Paul Harris and Dale Steyn as the tourists clinched an impressive victory.
