Jaidee back in front
Thai golfer Thongchai Jaidee wasted no time regaining the lead when the Volvo Champions resumed at Durban Country Club on Saturday.
The former paratrooper birdied the second and third holes while overnight pacesetter Louis Oosthuizen flew the green at the short second and bogeyed.
They were 13 under par and 11 under respectively, with South Africa's 2010 Open champion down into a tie for second with Scotland's Scott Jamieson.
Winner of the Nelson Mandela Championship at nearby Royal Durban last month, Jamieson set off again with a bogey after missing the first green, but almost holed-in-one at the 188-yard second and tapped in for birdie.
It was a three-horse race at the halfway stage, but Frenchman Julien Quesne eagled the third and with that climbed to outright fourth place on seven under, still six adrift of Jaidee.
Disappointment for the home crowd came with Ernie Els bogeying the first and short fourth to find himself 11 back.
Jaidee's advantage became three - the same that he held after his opening 65 - when Oosthuizen and Jamieson both failed to get up and down from sand on the 180-yard fourth.
They slipped to 10 under and were only one ahead of Quesne, who followed his eagle with birdies at the fifth and sixth.
But then came a bogey on the next for last year's surprise Andalucian Open winner.
Oosthuizen was nothing like the player who, like Jamieson, shot 64 in the
He drove into a bush down the long eighth, had to take a penalty drop and by taking six was four over for the day and down to joint fourth with England's Danny Willett.
Jaidee, though, had done the same at the eighth and at 12 under he was caught when Jamieson hit his approach to the same hole to within five feet of the flag and made it for eagle.
They were three clear of Quesne, who turned in 33 and birdied the 560-yard 10th.
Jamieson took a two-stroke leap by chipping in from around 25 yards at the 11th and then making a 12-footer on the next.
He stood 14 under, with Jaidee 12 under and Quesne nine under alongside Willett and Oosthuizen, who birdied the 10th and 11th only to drop another shot at the 12th.
