A double-bogey at the final hole cost England's Justin Rose a £725,000 victory at the Nedbank Golf Challenge in Sun City, South Africa.
The European number one and home favourite Trevor Immelman, who had both started the day on 16 under, were level on 17 under on the 18th tee but Rose pulled his drive into trees, had to lay up short of the water but then flew the green and duffed a chip back to card a six.
Immelman had problems of his own and could make only bogey — his third in succession — but still won on 16 under with a level-par final round of 72.
The South African, a late invitation to the 12-man event, had appeared to have blown his chances after squandering the two-shot lead he held after 15 holes.
On the short 16th both pulled their tee shots but Immelman chipped and two-putted while Rose splashed out of a bunker to the edge of the green and holed from 12 feet.
At the next Rose salvaged another par after almost driving into the water while Immelman bogeyed from just off the back.
"This event is what we in South Africa have always regarded as
Africa's
major," said Immelman.
"Ever since I was a kid I've watched it on television. I dreamed of playing it one day, and then I dreamed of winning it.
"Today that dream has come true and it is a very special moment for me."
Three-time champion Ernie Els shot a disappointing 72 to finish third on 11 under while England's Luke Donald's 73 was only good enough for a share of sixth on five under.
