DUBAI — Rory McIlroy completed a lucrative double when he won the DP World Tour Championship and retained his Race to Dubai crown yesterday following a thrilling victory that was built around a final-round of six-under 66.

The world No3 had to battle hard and then get over an errant tee shot on the 17th hole that ended in the water to beat overnight leader Andy Sullivan of England, who fought tooth and nail and forced McIlroy to dig deep.

The win was worth $3.208m for McIlroy — $1.33m for winning the DP World Tour Championship and $1.875m bonus for winning the Race to Dubai.

McIlroy, who will remain the world No3 behind Jason Day and Jordan Spieth despite the win, finished on 21-under par 267 for the tournament.

That was one shot better than Sullivan, who added a second successive 68 at the weekend to finish on 20-under par 268.

By winning the tournament, the Northern Irish star made sure none of the permutations needed to be worked against the six other players in the reckoning for the Race to Dubai crown could work.

England’s Danny Willett (70) gave it his all, but two late bogeys meant he finished tied for the fourth place at 13-under par 275.

SA ’s Branden Grace made a five-under par 67 to finish alone in third place at 15-under par 273.

After trailing Sullivan for most part of the day, McIlroy built a two-shot lead over the world No53, who was looking for his fourth win of the season on the European Tour, with back-to-back birdies on the 14th and 15th holes.

But, after the leading group was made to wait on the 17th hole, McIlroy failed to draw his tee shot and splashed into the water.

He pitched to nearly 40 feet from the cup and with Sullivan making a regulation par, a two-shot swing looked imminent.

However, McIlroy made what he called the "best bogey of his life" to limit the damage to one shot, and secured the win with a par on the 18th.

"It’s probably the longest putt I’ve ever made for a bogey. I don’t think there’s been one that’s come at a better time ," said McIlroy, who won his third Race to Dubai honour in the past four years.

"To be European No1, yeah, that was a goal of mine at the start of the year. It was a goal of mine in the middle of the year and it was definitely a goal coming into these last few weeks."

The deficit was down to one after eight holes and McIlroy could have made the turn tied for the lead if not for a stunning chip-in for par from behind the ninth green by Sullivan.

On the back nine, McIlroy finally caught up with Sullivan with back-to-back birdies on the 11th and 12th holes.

Korea’s Byeong-hun An won the Sir Henry Cotton Rookie of the Year award on the European Tour by finishing ahead of his closest challenger, Matthew Fitzpatrick of England, in the Race to Dubai.

Englishman Justin Rose, the world No5, finished on seven-under par 281.

Sweden’s world No6, Henrik Stenson, the champion in Dubai for the past two years, finished tied for last at three-over par 291 after a round of 73.
