DURBAN, South Africa -- Scott Jamieson of Scotland stormed to a five-shot lead in the Volvo Champions as Louis Oosthuizen's challenge faded away in the third round at Durban Country Club on Saturday.
Jamieson began the day a stroke behind the former British Open champion, but his 4-under-par 68 moved him to a 15-under total and five shots clear of Oosthuizen (74), Thongchai Jaidee of Thailand (73) and Julien Quesne of France (67).
Padraig Harrington (67) and Francesco Molinari (68) were another two strokes back in the event for European Tour winners.
Jamieson won his first European Tour title a month ago in the season-opening Nelson Mandela Championship, and now he's one round away from earning the "Durban Double."
"It's been another great day and while I didn't play as well as I did the first two days, especially yesterday from tee to green, I managed to score well, which is the main thing," Jamieson said. "So I'm delighted to be in the position I'm in.
"The experience of winning the Nelson Mandela in a playoff under the extreme pressure with a first European Tour title on the line gave me a lot of confidence that I've taken into this week."
Jamieson eagled the par-5 eighth hole when he landed a 198-yard 5-iron to five feet and holed the putt. He also birdied three holes in succession from the 11th.
For three days, Jamieson has seen off three of the bigger names in golf.
He played the first round in the company of Harrington and finished a shot ahead of the Irishman. On day two he was six shots lower than Thomas Bjorn, and on Saturday he pulled the rug out from under crowd favourite Oosthuizen, who couldn't overcome four bogeys on the front nine.
"You always have your eye out, comparing yourself to them," Jamieson said, "but yeah, I managed to beat them through the week, so that was nice."
