Hong Kong: Thailand's Udorn Duangdecha stole the thunder from a quality field to lead the Hong Kong Open with a dazzling eight-under-par first round 62.
Dutchman Robert-Jan Derksen was one behind while holder Lin Wen-tang of Taiwan shared third place on 64 with Frenchman Gregory Bourdy, Briton David Dixon and Thai Thongchai Jaidee at the USD 2.5 million event co-sanctioned by the European and Asian tours.
Race to Dubai leader Lee Westwood carded a 66, a score matched by fellow Briton Rory McIlroy who is second on Europe's money list.
Asia's first major winner Yang Yong-eun of South Korea and former British Open champion Mark O'Meara also fired four-under-par 66s.
Derksen won a gold bar for a hole-in-one in Hong Kong two years ago and he set the early pace after birdying five of the last six holes, his only blemish a three-putt at the 16th.
However Asian Tour member Duangdecha, dressed in bright 'flower power' trousers, charged into the lead after reeling off 10 birdies at Fanling.
The 39-year-old only missed out on the course record after bogeying his final hole, the par-four ninth.
Lucky Pants
"They are my lucky pants," the flamboyant Duangdecha told reporters. "I always play in colourful trousers and I have enough in the wardrobe to last me all weekend.
"(A 62) might surprise everyone but I don't think it surprised me too much. It was a shame to finish the round by three-putting the last but I'm delighted with the round."
Hong Kong debutant Westwood and McIlroy are locked in a battle for the USD 1.5 million bonus on offer for Europe's number one at the season-ending Dubai World Championship.
The Englishman leads Northern Irishman McIlroy by around $80,000 after the 20-year-old climbed to second in the money list by finishing fourth at last week's WGC-Champions Tournament in Shanghai.
"The greens are puzzling," said Westwood who finished tied for eighth in China. "I am at a disadvantage having only played the course once before (in practice).
"It is pretty obvious tee to green but there is a big advantage having played a few tournaments around here so to start with a 66 I am delighted."
McIlroy was equally positive after his round.
