Jeunghun Wang had an eagle and six birdies in a superb third round on Saturday to take a 3-shot lead into the final day of the Nedbank Golf Challenge in South Africa.

Wang's 8-under 64 took him to the lead after starting five shots behind overnight leader Alex Noren. The 21-year-old South Korean went bogey-free to go 11 under overall, ahead of home favorite Louis Oosthuizen.

England's Andy Sullivan was a shot behind Oosthuizen, and Noren is in a tie for fourth with Branden Grace.

There was a recovery from Henrik Stenson, with the European Tour's Race to Dubai leader producing a 3-under 69 to climb into a tie for sixth. Stenson is still seven shots behind Wang and needs to win to wrap up the money list title before the season-ending World Tour Championship next week.
