Marc Leishman produced an impressive performance from the front to win the Nedbank Challenge by six shots in Sun City.
The Australian started the final round leading by one shot, and the pressure was on after he bogeyed the third hole to hand a boost to the chasing pack.
Leishman's response included six birdies on the way to a five-under-par 67 to ensure he finished on 19-under at the top of the leaderboard.
Henrik Stenson was unable to catch the leader on a frustrating day for the Swede as he carded four birdies and four bogeys in a round of 72.
Chris Wood's four-under 68 earned him third place, while Danny Willett, who won the event last year, joined Victor Dubuisson, Branden Grace and Robert Streb in a tie for fourth on eight-under.
