Louis de Jager will head into the weekend as the highest placed South African at the Hero Open after a brilliant second-round 66.
De Jager enjoyed a solid bogey-free display on Friday in a round that included six birdies, which will see him start moving day on four under par.
He will also be the only South African in contention after the cut was set at two under par.
After a good opening round on Thursday, Justin Walters suffered a disappointing second day out at the Arden Marriott Hotel and Country Club.
A nasty five-over-par 77 saw him drop 64 spots on Friday to conclude on one under par
Justin Harding also found Friday’s round rather tough with a three-over 75, while Dean Burmester is a further stroke behind on two over par, alongside Haydn Porteous.
Bryce Easton, Brandon Stone and Zander Lombard bowed out of the event after difficult rounds as well.
Spain’s Sebastian Garcia Rodriguez and Englishman Sam Horsfield will however be the leaders when play gets under way on Saturday after finishing their second rounds on 13 under par
