Sweden's Alex Noren claimed an incredible fourth European Tour title in his past 11 events with a stunning final round in the Nedbank Golf Challenge.
Noren began the day five shots behind South Korea's Wang Jeunghun, but carded a closing 63 at Sun City to finish 14 under par, six shots clear of Wang.
Ranked 108th in the world after missing the cut in June's US Open, Noren will be inside the top 10 for the first time when the standings are updated on Monday after adding the Nedbank title to victories in the Scottish Open, European Masters and British Masters.
The 34-year-old birdied the first three holes at the Gary Player Country Club and picked up further shots on the fifth, seventh and eighth to reach the turn in 30.
And when he holed from 25 feet for an eagle on the 10th and chipped in for a birdie on the next, the first 59 in European Tour history was a distinct possibility.
A bogey on the 14th put paid to that and Wang's birdie on the same hole cut his deficit to two shots, only for the 21-year-old to bogey the next two holes as Noren birdied the 16th.
Wang, who was just 20 when he became the youngest player in European Tour history to win consecutive events earlier this season, also bogeyed the 18th but held on to second place, a shot ahead of Andy Sullivan, Branden Grace, Ricardo Gouveia, Alejandro Canizares and Victor Dubuisson.
