South Africa's Haydn Porteous carded a final round 69 to win his maiden European Tour title at the Joburg Open.
Porteous became the second South African in as many weeks to open his account after Brandon Stone's triumph at the South African Open last Sunday.
The 21-year-old, who had gone into the fourth day on the East Course at the Royal Johannesburg & Kensington Golf Club tied with compatriot Zander Lombard and England's Anthony Wall on 15 under, completed a flawless round which included three birdies to finish two shots clear on 18 under.
Porteous told the European Tour's official website: "Words can't describe how I feel right now. It's surreal to be honest.
"I've been battling with my golf for the last few months and hats off to [fitness coach] Garth Milne for all the strategy and game-plan and gym.
"I started to hit a few fairways and a lot more greens and gave myself some chances to make birdie. Unfortunately the putts didn't go in, but I was keeping the pressure low and making sure I was going to be making par."
Lombard's hopes were dashed as he dropped shots on the ninth, 11th and 14th holes on his way to a 1-under 71, leaving him in second place.
Wall had to settle for a four-way tie for third after he finished the tournament with a 72 following three sub-par rounds with his two birdies, one of them at the first, cancelled out by two bogeys.
But he at least had the consolation of qualifying for The Open at Royal Troon along with Porteous and Lombard as a result, just as he did last year.
