Tiger Woods fired a six-under-par 66 in Hawaii on Wednesday to surge past Jim Furyk and defend his title at the one million-dollar Grand Slam of Golf.
Woods, the world's No. 1 player, captured his seventh title in this unofficial postseason event that has been held nine times.
He finished with a 36-hole total of eight-under 136, two shots better than Furyk, who carded a 71.
Woods started the round three strokes off the pace but quick applied the pressure with birdies at the second and third holes.
Furyk maintained his slim lead as both he and Woods birdied the par-five sixth.
Winner of the British Open and PGA Championship this year, Woods, caught Furyk with a birdie at the ninth hole and took the lead when Furyk missed a six-foot par putt for his first bogey of the tournament at the par-four 10th.
Amid some rain at the oceanside Poipu Bay Golf Course, Woods made a 15-foot birdie at the par-four 15th, where Furyk missed a six-footer for birdie and fell two shots back.
Woods won 500,000 dollars.
US Open champion Geoff Ogilvy of Australia began the day one shot off the lead but carded a two-over 74 and finished at 142.
That was three shots better than Canadian Mike Weir, who also had a 74.
The event is supposed to feature the winners of the year's majors. But Masters champion and 2004 winner Phil Mickelson decided not to participate and was replaced by 2003 Masters champion Weir.
With Woods winning two majors, Furyk was given a berth for finishing second on the PGA Tour money list. He won his only previous appearance here in 2003 - the year he won the US Open.
