The American pair fired six birdies in the alternate-shot final round at Mission Hills Blackstone course to finish on 24-under 264 overall, notching the 24th US win in the history of the tournament.

English pair Ian Poulter and Justin Rose had the final day’s best round with a 63 to tie for second at 22-under with Germany’s Martin Kaymer and Alex Cejka (69).

Ireland’s Rory McIlroy and Graeme McDowell led by two strokes going into the final round but could only manage an even-par 72 to finish joint fourth with Australia, the Netherlands and Scotland.

The American victory was the first since Tiger Woods and David Duval claimed the title 11 years ago. The event was annual up to 2009, and this year’s tournament was the first in the new biennial format.

“We really clicked. It’s fantastic to win for the US,” said Woodland.

The US duo built a two point lead over Germany from the halfway stage and after a rare slip with a bogey at the par-3 11th, the Americans responded with birdies on the next two holes and then pars the rest of the way to claim victory.

“Undoubtedly the shots on the 12 and 13th were key. It was a great moment and to shoot a par when you expected a bogey,” said Kuchar.

England seemed well out of contention heading into the final day eight shots off the lead, but soared into contention. However they needed more than one of the leading teams to falter. Instead it was only Ireland which came back to the field.

World No. 2 McIlroy was well below his best, fluffing a series of shots, including a putt on the 18th which would have given Ireland a share of the runners-up check.

The rot set in for the tournament favorites when they suffered a penalty stroke on the 6th and the Irish duo recorded four bogeys.

They shared fourth with Australia’s Richard Green and Brendan Jones (69), plus Scotland’s Stephen Gallacher and Martin Laird (66) and the Dutch pairing of Robert-Jan Derksen and Joost Luiten (68).

Like Ireland, South Africa also had a pair of major winners who faltered on the final day, with Charl Schwartzel and Louis Oosthuizen only able to record a 74 to quickly drop out of contention.

Defending champions Italy, represented by Edoardo and Francesco Molinari, also had a final-round 74 to finish 17th, ten shots off the winning score.
 

Meantime, Greg Chalmers followed up his Australian Open title win earlier this month by winning the Australian PGA Championship at Coolum on Sunday after beating Marcus Fraser and Robert Allenby in a three-way playoff.

The 38-year-old Australian left-hander was the most consistent on the only playoff hole, the par-four 18th, when he made par, while compatriot Allenby missed his long par putt following a wayward drive off the tee at the Hyatt Regency course on the Sunshine Coast.

Fraser, another local player, had fallen out of contention when he found the water off the tee and then the bunker on the back side of the green.

“I was surprised to see that par was good enough because I thought we would have to birdie this hole, but that’s how it goes some times,” Chalmers said in a greenside interview.

“The putt was the hardest thing and to have won it now and coupled with the Australian Open, I’ve got two of those, I’m just thrilled.”

Chalmers will now seek to join Allenby as the only players to win all three Australian tournaments in the same year when he plays the Masters at the Victoria Golf Club in Melbourne from Dec. 15-18.

Fraser, who underwent neck surgery earlier this year that saved his career, made it into the playoff when he birdied two of the last three holes, making a mammoth putt from almost 50 feet on the last to notch a three-under 69.

Allenby (68) also qualified for the playoff when he made a birdie on 18, while Chalmers had earlier taken the outright lead when he birdied 17 and made par on 18 to record a 12-under 276.

Overnight leader Kim Kyung-tae and second-placed Bubba Watson faltered early in their rounds, with Kim making a double bogey seven on the fifth, while Watson opened with a double-bogey and had bogeys on the second and fourth.

Kim (76) finished in a three-way tie for sixth with Australians Marc Leishman (69) and Nick O’Hern (67) on nine-under-par 279, while the big-hitting Watson (77) was tied for 12th with Australian Brad Kennedy (69) on seven-under.
