KAPALUA, Hawaii -- A new year brought out the best in Dustin Johnson, who powered his way to an 8-under 65 and an eight-shot victory Sunday in the Sentry Tournament of Champions.
In a field that featured the top five players in the world, Johnson made a strong opening statement that the No. 1 ranking he has held for nearly a year might be difficult to take away.
Johnson stretched a two-shot lead to six shots at the turn, then delivered the biggest moment of the week with a drive on the par-4 12th hole that stopped 6 inches from the cup for a tap-in eagle. He also drove the par-4 14th hole.
He finished at 24-under 268. The eight-shot margin of victory was his largest ever, and it was one short of the tournament record set by David Duval since this event moved to Kapalua in 1999. Jordan Spieth also won by eight shots in 2016.
Jon Rahm made his Kapalua debut by closing with a 69 to finish second. The 23-year-old from Spain moved to No. 3 in the world.
Harman closed with a 72 to finish third, while Hideki Matsuyama(66), Pat Perez (69) and Rickie Fowler (70) were another shot behind.
"I got off to a great start, and I want to keep it going,'' Johnson said. "Everything is going in the right direction."
