Davis Love III returned to the day job and found an American who failed to make his Ryder Cup team just too hot to keep pace with at the Justin Timberlake Shriners Hospitals for Children Open.
Ryan Moore was only 40th on the United States Ryder Cup points list but showed his quality with a 10-under-par 61 in his opening round at TPC Summerlin in Las Vegas.
Love was also under par, but only three under, and finished the day tied for 29th.
After the disappointment of Medinah, where as captain he saw his side give up a 10-6 lead to lose the match to Europe over the course of the singles, Love was keen to return to action.
His round was nothing if not steady, with birdies at the fourth, fifth and seventh and 15 pars.
Moore, by contrast, was tearing up the course and the 30-year-old was not the only one, with Zimbabwean Brendon de Jonge just one off the pace and American's Tim Herron and John Huh on eight under.
Starting at the 10th, he was seven under through eight holes and almost reached the turn at nine under when his approach to the par-four 18th hit the flag and damaged the cup but rolled so far away he could only two-putt.
Moore's only dropped shot came at the eighth hole, his 17th, but the graduate of the University of Nevada-Las Vegas repaired the damage by making birdie at the next.
"It didn't feel like a great round early," Moore said. "I did get off to a nice start. I birdied 11, 12, 13, and then eagled 15. But it wasn't just perfect, perfectly sharp, hitting it right where I'm trying to every single time.
"I was just hitting good, solid shots and converting.
"Then on 18, I was seven under going into that hole, and I holed it out and bounced off the pin to about 40 feet.
"That's when it was like, 'Oh, I guess I'm playing pretty good today'.

"So it was at that point obviously I felt pretty good making the turn shooting 29. I was just trying to keep doing what I was doing. That was just simply out it in the fairway, give myself chances with my wedge and nine-iron, and I knew I was going to convert some of those chances."
His round tied the course record. De Jonge, Herron and Huh did not drop a shot between them on a course set up for low-scoring, which saw US pair Chris Kirk and Justin Leonard tied with Sweden's Jonas Blixt for fifth place on seven under 64.
Fijian veteran Vijay Singh was in a group on five under which included Scotland's Russell Knox, the leading Briton.
England's Gary Christian was alongside Love on three under.
