Aiken leads in Johannesburg

Thomas Aiken led the Joburg Open early through the third round after his solitary birdie through five holes put him a shot clear on the east course of the Royal Johannesburg and Kensington Golf Club.

The South African was a shot behind halfway leaders Charl Schwartzel, Garth Mulroy and Jamie Elson at the start, but all three dropped shots during their opening four holes.
