Kevin Na birdied four of the first eight holes and shot a four-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 five feet for birdie at the par-4 2nd. 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 cosy course made famous by Ben Hogan.
"On the first tee, I saw that wall, looked at the names, right below Justin Rose," Na said, referring to the defending champion. "And in my head, I engraved my name on it. I was just trying to visualise success before I teed off.
"They say this is a golf course that I've had the most leads in a tournament, so it tells you how much I like this place and how well I've played here."
Local favourite Jordan Spieth's strong putting disappeared in a two-over 72, as the Dallas native finished eight shots back to remain without a victory since his third major title at the 2017 Open Championship.

Jim Furyk's hopes faded when the 2003 US 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.
"He wasn't letting up, so I knew I was going to have to make three or four birdies coming in," Finau said. "I gave myself the looks to do it. Just wasn't able to make it happen."
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 five over.
Victorian Aaron Baddeley jumped five places to finish tied 48th after finishing his final round with an even-par 70.
