Branden Grace clinched the Nedbank Golf Challenge on home soil with a one-shot victory over Scotland's Scott Jamieson.
The South African hit all 18 greens in regulation en route to a final-round 66 and 11-under winning total at the Gary Player Country Club.
Grace moves alongside Louis Oosthuizen into a tie for fourth on the list of all-time South African European Tour winners, behind only Ernie Els, Retief Goosen and Charl Schwartzel.
The 29-year-old is the first home winner of the Nedbank Golf Challenge since Trevor Immelman in 2007 and moves into the top 10 on the Race to Dubai.
"This is awesome," said Grace. "This is the one event that as a South African you want to win. It's Africa's Major for a reason and what a special place it is.
"There's a lot of history and a lot of great winners on the trophy and I'm very glad to be able to put my name on the trophy as well.
"It's a very special week, we found out on Wednesday we're having a boy.
"I had to stay patient and I had to take the chances when they came my way. I missed a couple of short ones but I think the big key was the putt on 16."
