Brandon Stone ran away from his challengers to win the Alfred Dunhill Championship by seven shots on Sunday for his second European Tour title.
Stone finished with a 5-under 67 at Leopard Creek Country Club for 22 under overall, extending his advantage over the chasers after going into the final round three shots ahead.
Stone made seven birdies and two bogeys to secure a comfortable victory for the 23-year-old South African. Richard Sterne was second.
Stone was put under early pressure by playing partner and defending champion Charl Schwartzel, who made three birdies in the first six holes.
The tide turned at No. 7 when Stone made birdie and Schwartzel a bogey. Four-time winner Schwartzel later slipped up with a triple-bogey and a double-bogey on Nos. 15 and 16 to finish tied for fourth.
