Durban - Scott Jamieson is set up to win two European Tour events in Durban within two months after taking a five-shot lead on Saturday after three rounds into the Volvo Golf Champions.
Jamieson fired a four-under-par 68 for a total of 201 at Durban Country Club to move clear of Thai Thongchai Jaidee, Julien Quesne of France and South African Louis Oosthuizen.
The Scot won the first event of the 2013 European Tour - the inaugural Nelson Mandela Championship - last month at another Durban course after the tournament was cut to two rounds by torrential rain.
He is alone among the 33 competitors in having shot three sub-70 ruonds over the 6,111-metre track, opening with a 69 and shooting a second-round 64 to be one stroke behind Oosthuizen at the halfway stage.
Jamieson began the third round erratically with a birdie and two bogeys within four holes before an eagle three at eight enabled him to turn one under par.
He made a much better start to the inward half with three birdies on the trot from 11 only to bogey 17 before closing with another birdie and an advantage that offers hope of a second European Tour success.
Oosthuizen flopped amid much anticipation that he would stretch his lead in the penultimate round and most of the damage was inflicted on the first nine where he bogeyed four holes.
The Volvo Champions is restricted to 2012 European Tour winners and those with more than 10 career titles on the circuit, and there was no halfway cut because of the small field.
