Louis Oosthuizen started the day with a one-shot lead at the AfrAsia Bank Mauritius Open but lost it with consecutive bogeys at the 4th and 5th holes. He made five birdies over the next ten holes then bogeyed the 16th and birdied the final hole for a 69 to win by two shots.
The South African, who co-designed the course at Heritage La Réserve GC with Peter Matkovich, had won his first title in five years at the weather-delayed Alfred Dunhill Championship on Monday.
"Golf is the strangest thing," he said. "The last five weeks I've not done a lot with golf, I've played a few rounds and when I got to Leopard Creek I was working on a small little thing. I started hitting it really good and I know I'm putting well and then I just carried on with that momentum."
"I started off very poorly and that errant second shot on 16 made it interesting but I hit a few good shots coming in... I'm glad I held onto it," he continued.
"I'm glad I could pull this off this week, it's sort of a dream come true being able to play a tournament on a golf course you helped design and end up winning it.
"This is the first event my daughters have been to where I won, this is very special."
England's Laurie Canter closed with a flawless 68 to finish second at 15-under.
Fellow Englishman Daniel Brown shot a 65 for a share of third place at 14-under alongside South African Jacques de Villiers who closed with a 71 and Sweden's Sebastian Söderberg who shot the best round of the day featuring ten birdies and a single bogey for a 63.
