Scott Jamieson leads Volvo Golf Champions by five shots at Durban Country Club

Scott Jamieson: Commanding lead after 54 holes

Scott Jamieson is on the verge of a Durban double after moving five shots clear in the Volvo Champions Golf in South Africa.

The Scottish ace, who won the Nelson Mandela Championship at nearly Royal Durban just seven weeks ago, carded a third round four-under 68 at Durban Country Club on Saturday as overnight leader Louis Oosthuiizen stumbled unexpectedly.

Oosthuizen could only card a two-over 74 and slipped back into a three-way tie for second alongside Thailand's Thongchai Jaidee (73) and Frenchman Julien Quesne, who fired an impressive five-under 67.

That trio are two in front of Padraig Harrington (67) and Francesco Molinari (68), who both shot their best rounds of the week.

Jamieson was slow out of the blocks on Saturday with bogeys at the first and fourth but he hit a brilliant second shot to five feet at the eighth and made it for eagle.

A hat-trick of birdies from the 11th moved him three in front and despite a bogey at 17 he chipped close at the last to pick up a further stroke and finish at 15-under.

Oosthuizen, who held a one shot overnight lead, went to the turn in a worst-of-the-day 40 and although he found four birdies on the back nine, two more bogeys meant he signed for a 74.

Jaidee had moved three shots clear after birdies at two and three but they were his only gains of the day as bogeys at eight, 16 and 18 left him trailing by five at the close.

Hopes of a charge from Ernie Els were soon wiped out after two early bogeys and he's now 10 shots back after a 71.

Exciting possibilities

Jamieson came into the tournament as a member of the world's top 100 for the first time in his life - at 100th - but could end it with all manner of exciting possibilities opening up for him.

Never having played a world championship, he would be looking at a place in next month's 64-man Accenture Match Play in Arizona and being in the top 50 at the end of March would give him a dream debut in the US Masters at Augusta - the town where he went to college.

Not bad for someone who failed in his first three attempts to survive the European Tour qualifying school before coming through the Challenge Tour three years ago.
