FORT WORTH, Texas (AP) -- Kevin Na birdied four of the first eight holes and shot a 4-under 66 to cruise to a four-shot victory over Tony Finau at Colonial on Sunday.
The South Korean-born American opened with a two-shot lead and was in front by at least that many for the final 16 holes after putting his second shot inside 5 feet for birdie at the par-4 second. Na finished 13 under.
Na's third career PGA Tour victory, and second in 10 months, came after putting himself in contention with a second-round 62, one off the Colonial record. It was his third score at least that good in a span of six on the cozy course made famous by Ben Hogan.
Local favorite Jordan Spieth's strong putting disappeared in a 2-over 72 as the Dallas native finished eight shots back to remain without a victory since his third major title at the 2017 British Open.
Jim Furyk's hopes faded when the 2003 U.S. Open champion went in the water for double bogey at the par-3 13th on the way to a 73. The 17-time tour winner's last title was at Hilton Head in 2015.
Finau briefly was within a shot of Na early in the round, and the first-round leader was two back when Na birdied 14 about the same time Finau had a bogey at 16 to push the lead to four. Finau, looking for his second career win three years after his first, closed with a 68.
It's the first time since 2002-03 that consecutive Colonials were decided by more than one stroke. Defending champion Justin Rose, who won by three and was the highest-ranked player in the field at No. 3 this year, had his third score of par or worse, shooting 70 to finish 5 over.
