Second Test, Durban, day five: Australia 369 & 307-4d bt South Africa 267 & 297 by 112 runs
Shane Warne took his 34th five-wicket haul as Australia beat South Africa by 112 runs in Durban to secure an unassailable 2-0 lead in the series.
Warne made an instant impression when he came on to bowl
The home side were 91-0 before Warne struck with his third ball, luring AB De Villiers (46) out of his ground, and ousted Graeme Smith four overs later.
Mark Boucher battled for three hours in dismal light for an unbeaten fifty.
But with the light fading fast and only 7.2 overs left, Warne trapped last-man Makhaya Ntini lbw to finish with 6-86.
Smith was beginning to look like the granite opener who defied England with two double centuries in 2003.
The target of 410 was always likely to be academic, but it seemed as though the home side would at least save the match and keep the series alive.
But things changed when Warne was introduced into the attack after 17 overs of the morning.
His third ball was beautifully flighted and had enough spin to unbalance De Villiers as he pushed forward, Adam Gilchrist making the stumping look easy.
Smith was distinctly unimpressed by his dismissal, believing the ball struck his arm, not glove, as he swept and the ball ricocheted via Gilchrist's gloves into Langer's midriff.
Langer just hangs on at leg-slip to dismiss Smith controversially for 40
Jacques Kallis only lasted 32 deliveries before missing an attempted sweep off Warne being given out lbw.
Herschelle Gibbs also failed to get through to lunch after Stuart Clark pitched one on a length that reared up horrifically off a crack. Gibbs could only fend it off the glove to Warne at slip.
After lunch, Clark produced another hostile one that climbed at Ashwell Prince, and the left-hander was caught on the glove as he tried to take evasive action, the ball looping to square-leg.
Jacques Rudolph cut successive boundaries off Brett Lee but became Warne's fourth victim when gloving to silly point.
And when Shaun Pollock was bowled by Lee, the game looked up with only three wickets remaining at tea.
However, the final session was an intriguing battle with Boucher and the tail-enders defying Australia for long periods.
Nicky Boje played his shots before departing for 48, driving Michael Kasprowicz into the ring of fielders patrolling the covers.
Boucher and Nel had several short-pitched deliveries to contend with in the gradually fading light, which eventually led to the umpires telling Gilchrist he could not bowl Lee or Clark.
That meant Andrew Symonds eventually having to bowl his off-spinners in partnership with Warne.
The finish was remarkably similar to the Durban Test of 2004 when England were left needing only two wickets to beat South Africa when bad light ended the match.
Warne threw everything at last man Ntini - flippers, sliders and vicious turn away from and into the right-hander.
The final dismissal was another contentious one, Ntini adjudged lbw not playing a shot to one that hit him outside off-stump but was not spinning in as much as some other Warne specials.
Australia's impressive effort was done without skipper Ricky Ponting, who was forced to return to the team hotel because of a bug.
