American Zach Johnson recorded his third win in six tournaments with a thrilling one-shot victory in the Tournament of Champions in Hawaii.
The 37-year-old shot a bogey-free seven-under 66 to overturn
an overnight two-shot deficit
and win on 19 under.
Jordan Spieth, 20, birdied the last two holes to move to 18 under but Johnson parred the par-five 18th to win.
Webb Simpson and Kevin Streelman were tied third on 17 under while defending champion Dustin Johnson finished sixth.
“Getting the ball in the fairway and giving my wedges a chance was crucial”
Spieth, Simpson and Dustin Johnson began the day in a tie for the lead and five players entered the back nine with a chance to win, but it was Johnson who delivered, shooting four birdies in five holes from the 12th following some fine work with his wedges.
"Getting the ball in the fairway and giving my wedges a chance was crucial," said the 2007 Masters winner.
"It's about plotting my way, putting myself in a yardage spot that I know is going to give me an opportunity."
Victory for Johnson on the Plantation Course at Kapalua follows success in the World Challenge in California last month,
where he beat world number one Tiger Woods in a play-off,
and the BMW Championship in September.
It was the 11th title of his career, as he begins his 11th season on tour. Since his rookie year in 2004, only Phil Mickelson and Vijay Singh have won more titles in that period.

Spieth looked on course to become the youngest player to record two PGA Tour wins since Ralph Guldahl in 1932 when he birdied the two par fives on the front nine to take a one-shot lead at the turn.
He too had no dropped shots in his four-under-par round of 70 but three missed birdie opportunities on the back nine proved costly.
"I was very pleased with the finish, being able to birdie the last two holes and at least have somewhat of a chance on 18," said Spieth.
"But ultimately, 14, 15, 16 hit me hard in the middle of the back nine."
Jason Dufner was four strokes back in fifth, with Dustin Johnson, who made five bogeys, tied-sixth with Australian Adam Scott, Billy Horschel, Dustin Johnson and Matt Kuchar.
The solitary Briton in the 30-man field, Scotland's Martin Laird, finished 10 shots off the lead on nine under.
