Jeunghun Wang has moved into a three-shot lead at the Nedbank Golf Challenge in South Africa after shooting a 64 in the third round on Saturday.
The 21-year-old South Korean's eight-under-par round included an eagle and six birdies on the Gary Player course, on a day in which only six of the 72-player field managed to break 70.
Wang's effort lifted him to 11-under-par, three clear of home favourite Louis Oosthuizen, who bogeyed the final two holes.
England's Andy Sullivan shot a 68 to move third on seven-under, while overnight leader Alex Noren's 75 left him six off the lead.
Race to Dubai leader Henrik Stenson, meanwhile, is seven shots behind Wang after a 69, with Danny Willett on par with a 67.
