Charl Schwartzel was both surprised and delighted to record his second straight mammoth victory after cruising to the Alfred Dunhill Championship title.
The former Masters champion has struggled for form for much of the year, but he followed up his 11-shot win in Thailand last week with a remarkable 12-stroke triumph at Leopard Creek.
"That doesn't happen often," said the South African, who closed with a three-under 69 to post a tournament-record score of 24 under par.
"Normally after a win by such a big margin, it's hard to put up the same show the next week. It's satisfying to continue that form and play the same sort of golf. I keep talking about consistency, and mine is back where I like it to be."
Schwartzel collected the first of his eight European Tour titles at Leopard Creek in 2004, and he has also had four runner-up finishes at the picturesque venue.
"It's always been a special place for me," he added. "This is where I can almost say my career started and it's always stayed close to my heart.
"It's nice to have continued my form from last week. I was saying a month and a half ago it's been a pretty disappointing year.
"Slowly and surely I started to swing the club a lot better, back to how I did when I won The Masters, and I actually got excited to play again.
"It started at the SA Open and from there got better and better. It's been a pretty good year now."
