Langley was not entirely new to big-time golf. He qualified for two U.S. Opens and tied for low amateur — with Henley, no less — at Pebble Beach in 2010.
But considering the nerves he felt on the first tee, and going around this tight course without a bogey, he didn't hesitate to call this round his best ever as a pro.
Adding to the dream day was being alongside Henley, one of his closest friends.
Henley also has a strong pedigree, having won on the Nationwide Tour as an amateur and twice more last year to earn his card.
As they walked up the 16th fairway late in the afternoon, the sun starting to slide toward the Pacific horizon and the skinny palms swaying in the wind, they couldn't help but think back to one year ago.
They were playing in a Hooters Tour event in Florida, Henley missing the cut and Langley barely making it.
"We were on the range trying to help each other find it," Langley said. "We were just walking up 16. You could see the ocean behind, PGA Tour signs everywhere. We looked at each other and realized this is pretty cool. To look back one year ago and to know that we weren't here ... we were in a far different place."
And now they're the top names on the leaderboard after one round of the first full-field tournament of the year.
They also had company.
Morgan Hoffman, another rookie, opened with a 66 in the morning. Ben Kohles, who turned pro last summer and won his first two starts on the Web.com Tour, had a 67.
There was room for veterans, too.
Piercy made it look like a breeze, especially compared with the vicious gusts last week at the Tournament of Champions that didn't start until Monday and ended 29 hours later on Tuesday. In a more gentle breeze, and on more traditional greens of Waialae, he played bogey-free and had a pair of two-putt birdies from inside 12 feet for a 66.
