UPDATE 1-Golf-Bourdy blitz gives Frenchman Hong Kong cushion

* Bourdy goes two clear after 63

* McIlroy boosts money list chances (Adds quotes)

HONG KONG, Nov 14 (Reuters) - Frenchman Gregory Bourdy conjured up a seven-under-par 63 to snatch sole possession of the lead after the third round of the Hong Kong Open on Saturday.

The 27-year-old carded seven birdies in a near-flawless display for a 16-under-par total of 194 and a two-stroke cushion ahead of joint overnight leader Robert-Jan Derksen.

Dutchman Derksen fired a 65 while Britain's Rory McIlroy went third on 11 under par after a 65 of his own, boosting his chances of overtaking Lee Westwood at the top of Europe's money list.

Westwood returned a 69 to end his challenge and leave him tied for 33rd on five under par at the $2.5 million tournament co-sanctioned by the European and Asian tours.

The Race to Dubai leader continued to struggle on his debut at Fanling, the Briton's hopes of keeping pace with McIlroy dented by three bogeys on the front nine.

Bourdy was delighted after a superb putting performance.

"It was a fantastic round -- one of my best ever rounds," Bourdy told reporters. "I am going to try and keep my putter warm because it was unbelievable today.
