Scott Jamieson will go in search of the biggest title of his career when he takes a one-shot lead into the final round of the Nedbank Golf Challenge on Sunday, with Shane Lowry seven back and requiring an inspirational charge to get in the mix.

Jamieson won the weather-shortened Nelson Mandela Championship in the 2013 European Tour season but taking home a cheque for just under £940,000 and a first Rolex Series trophy in Sun City would dwarf that achievement and boost his chances of making Thomas Bjorn's Ryder Cup team next year.

A bogey-free 67 moved the 33-year-old to eight-under and a narrow advantage over France's Victor Dubuisson, who signed for a 71 after holding a two-shot overnight lead.

Jamieson was a picture of consistency as he made birdies on the second, fourth, ninth, 13th and 14th.

Lowry endured a nightmare triple-bogey on 14 yesterday that halted his progress and the Offaly man gave up two shots on the eighth today. However three birdies got him home on level par for his round and one-under for the tournament. 

Padraig Harrington is two shots further back after a one-under 71, with Paul Dunne on seven-over following his one-over 73.

Two-time major championship winner Martin Kaymer was at five-under alongside home favourite Branden Grace, with another South African in Haydn Porteous and Italian Francesco Molinari two shots further back.

Englishman Tommy Fleetwood would take the Race to Dubai title with a win on Sunday but he was six shots off the lead after a third-round 67.
