Dustin Johnson has stormed home to win the US PGA Tour's Tournament of Champions by eight strokes in Hawaii.
World No.1 Johnson fired an eight-under-par 65 to finish at 24-under at Kapalua's Plantation course on Maui, with Spanish world No.4 Jon Rahm (69) a distant second.
American Brian Harman (72) was a shot further back in third.
Johnson's win is his second in the elite event for the previous year's tour winners, after triumphing in a windswept 2013 event.
The 33-year-old's 17th PGA Tour victory ensures he has a win in 11 consecutive seasons since debuting in 2008.
Starting the final day with a two-shot lead, Johnson made his intentions clear early on with four birdies in the opening 11 holes.
But the defining moment came with a display of his lethal power and precision with the driver at the 12th.
Johnson smashed a 430-yard tee shot which stopped six inches short of going in the hole for a rare hole-in-one on a par 4, but tapped in for eagle and never looked back with another three birdies coming home.
Australian world No.12 Marc Leishman, who led through 36 holes, bounced back from a nightmare third round 76 to shoot a bogey-free 67.
At 13 under, the 34-year-old Leishman finished tied seventh.
Fellow Australian Cameron Smith shot a 71 to finish at eight under, sharing 17th in his first start at the event.
World No.3 Justin Thomas signed off in style with a 67 in an otherwise disappointing title defence, improving his score to four under and tied 22nd.
The Tournament of Champions is a no cut event which this week featured seven of the world's top 10 golfers in a 34-man field.
