Scotsman Scott Jamieson leads France’s Victor Dubuisson by one shot on eight under going into the final day of the Nedbank Golf Challenge at Sun City.
Dubuisson held a two-shot lead after two rounds but his 71 allowed Jamieson to leapfrog him with a five-under 67.
Jamieson, 33, made five birdies and dropped no shots whereas 2014 Ryder Cup player Dubuisson bogeyed three par 4s.
Two-time major champion Martin Kaymer of Germany is three behind Jamieson, as is South Africa’s Branden Grace.
Italian Francesco Molinari shot a best-of-the-day 65 to sit on three under alongside South African Haydn Porteous.
Another Scotsman, David Drysdale, is a further stroke behind along with Englishmen Lee Westwood (74) – who was two behind Dubuisson after two rounds – Race to Dubai leader Tommy Fleetwood (67) and in-form Ross Fisher (73).
South Africans Charl Schwartzel and Louis Oosthuizen – who are both major champions – are also on two under, as is France’s Matthieu Pavon.
“I was much better on the greens today than I have been,” said Glaswegian Jamieson, who has played twice for GB&I in the Seve Trophy.
“It is exciting and I’m in a good position but tomorrow is a new challenge.
“There is still an awful long way to go but if I can do what I did today then I will be in with a good shout.”
