South African Haydn Porteous held his nerve for a bogey-free round of 69 to claim a maiden European Tour victory at the Joburg Open on Sunday.
Ireland's Paul Dunne finished five shots off the winner after a final round 72 - including five birdies and five bogeys. Three of those came on the back nine after he failed to build on birdies on the sixth, eighth and ninth.
Joint overnight leader Porteous made just five bogeys all week and hit every green in regulation at the Royal Johannesburg and Kensington Golf Club during his final round, while the chasing pack behind him struggled for the same consistency.
The 21-year-old finished the tournament on 18-under-par, two shots ahead of compatriot Zandersaf Lombard (71).
A further shot back was group of four players, all of who looked as though they may steal the limelight on Sunday before fading -- Swede Bjorn Akesson (68), England's Anthony Wall (72), Daniel Im (70) from the US and home hope Justin Walters (69).
The three top-ranked players have also earned their place at he 145th British Open at Royal Troon in July -- Porteous, Lombard and Wall, who qualifies ahead of the other players on 15-under-par by virtue of his world ranking.
