Geoff Ogilvy overcame a slow start to cruise to a six-stroke victory at the season-opening Mercedes-Benz Championship.

The Australian entered the final round at Kapalua's Plantation Course with a six shot lead but made a poor start with bogeys at his first two holes.

The 31-year-old saw his lead cut to just one after making his fourth bogey of the day at the eighth but he steadied himself with an eagle at the ninth before reeling off a run of four consecutive birdies from the 12th to power away from the field.

Ogilvy finished with an eagle, seven birdies and four bogeys for a five-under-par 68, putting him at 24-under, six ahead of Anthony Kim (67) and Davis Love III (67).

Sean O'Hair fired the day's best round of eight-under 65 to move up to fourth on 17 under, a shot ahead of fifth-placed Justin Leonard (70).

South Africa's Ernie Els (67) shared sixth place with Americans Zach Johnson (67), Kenny Perry (70) and DJ Trahan (71) on 15 under.
