Lee Westwood achieved a European Tour double yesterday by winning the season-ending Dubai World Championship and the money-list title.

An imperious eight-under-par 64 gave him a final 23-under total of 265 and a runaway six-stroke win over fellow Briton Ross McGowan (68).

Westwood's rival for the Race to Dubai money-list, Rory McIlroy (67) of Britain, was third on 273.

Englishman Westwood picked up €1.77 million ($2.37 million) for his double triumph.

McIlroy arrived in Dubai leading the money-list but the 20-year-old Northern Irishman was eclipsed by Westwood, who started the week in second position.

"The way I played under this much pressure and the circumstances of it all was about as good as I've ever played," Westwood told reporters after a flawless eight-birdie round.

"It's easily the biggest moment in my golfing career so far. I knew what I had to do and to go out and shoot 66-64 at the weekend, making no bogeys, gives me a lot of confidence for the future.

"My commiserations go out to Rory."

A dejected McIlroy said: "Every time I looked up at the leaderboard Lee was making birdies.

"He played unbelievable golf and fair play to him. Lee's different class and he deserves to be number one."
