John Peterson upstaged several big names to grab a two-shot lead at the Wells Fargo Championship as Tiger Woods made a solid start.
Peterson carded a six-under 65 at Quail Hollow, thanks largely to back-to-back eagles at the seventh and eighth holes Thursday.
The American mixed those two eagles with three birdies and just one bogey to hold a two-shot advantage.
On a congested leaderboard, Peter Malnati, Tyrrell Hatton, Johnson Wagner, Keith Mitchell and Kyle Stanley are at four under in a tie for second.
Rory McIlroy, who has six top-10 finishes in eight starts at Quail Hollow, made the best start of the big names.
The Northern Irishman opened with a three-under 68 to be tied for seventh.
Woods made a mixed start in Charlotte, North Carolina, shooting an even-par 71.
The 14-time major champion is playing at the tournament for the first time since 2012 and managed three birdies to go with as many bogeys.
"Ball-striking wise I'm fine, I'm right there," Woods said. "If I make a couple of putts, I'm two or three under par which is fine."
Justin Thomas, back at the scene of his 2017 US PGA Championship win, struggled to a two-over 73.
World number 14 Jason Day fared much better, carding a two-under 69 to be in a tie for 17th.
Brian Harman, last year's winner at Eagle Point Golf Club, could only manage a one-over 72.
