Alex Noren was three shots clear at the top of the leaderboard as the final round of the Nedbank Golf Challenge hosted by Gary Player neared its conclusion.
The Swede, who is chasing his fourth European Tour victory of the season, began the day six shots behind overnight leader Jeunghun Wang but notched an eagle, seven birdies and a solitary bogey in his first 14 holes to establish a comfortable lead.
The 34 year old made a dream start on Sunday, opening his fourth round with three straight birdies before rolling in from ten feet for another gain at the fifth to get to nine under.
Noren holed his 30-foot birdie putt at the seventh before repeating the trick from a similar distance at the next to move to 11 under.
When Wang carded a disappointing double bogey at the eighth, Noren briefly found himself with a one-shot lead, but the South Korean fired a birdie at the ninth to join him at the summit.
Noren regained the outright lead at the tenth, however, effortlessly knocking in his 25-foot eagle putt before chipping in for a birdie at the 11th to get to 14 under.
The World Number 17 dropped his first shot of the day at the long 14th when his par putt came up just short.
Wang was three strokes back in second after carding three birdies, two bogeys and a double bogey in his first 13 holes.
