Dustin Johnson held his nerve to close out a four-shot victory at the PGA Tour's season-opening Hyundai Tournament of Champions in Hawaii.
Johnson, who started the final round of the weather-shortened 54-hole event three clear of the field, did not have things all his own way, but saw off the challenges of Brandt Snedeker and Steve Stricker to emerge triumphant.
Johnson (68) eventually finished on 16-under-par with defending champion Stricker, who hit every green in regulation during his final round, having to settle for the runner-up spot on 12-under after a 69.
Snedeker (69) claimed third spot on 10-under, while US Ryder Cup colleagues Keegan Bradley (70) and Bubba Watson (71) shared fourth just one shot further back.
Early on it appeared that Snedeker would be the biggest danger to Johnson following a thrilling birdie-birdie-eagle-birdie run from the third hole which took him to within a shot of the leader.
Indeed, he had a birdie putt to move into a share with Johnson at the seventh hole, but would go on to three-putt for a bogey before dropping further shots at eight and then nine to fall dramatically out of contention.
Birdies for Johnson at six and seven saw him re-establish a comfortable cushion, but when he dropped a shot at nine and playing partner Stricker made birdie, the gap was back to just two.
A further birdie for Johnson at 12 gave him renewed breathing space but, with the winds picking up again, a wild drive into bushes at 13 would cost him a double-bogey that allowed Stricker to close to within one.
However, the leader responded in spectacular fashion at 14, chipping in from 25 yards for eagle after a monstrous drive at the par-four and opening what prove a decisive gap.
Johnson put a gloss on his triumph with a birdie at the par-five 18th and has now secured at least one victory in each of his last six seasons on the PGA Tour.
