The former British open champion Louis Oosthuizen has returned an 11-under-par 62 to surge into a two-stroke lead after the second round of the Africa Open at the East London Golf Club.
It's a welcome return to top form by the 2010 Open winner, who has not finished first in a European Tour event since lifting the Africa Open trophy at the club after a play-off 12 months ago.
South Africans Tjaart van der Walt (second-round 64), former Major winner Retief Goosen (68), first-round leader Thomas Aiken (69) and Jaco Ahlers (68) share second place.
