Phil Mickelson knows Quail Hollow as well as any course on the PGA Tour, and his comfort there was clear on Thursday as he earned a two-stroke lead in the opening round of the Wells Fargo Championship.
Mickelson carded a seven-under-par 64 to set the early pace in Charlotte, North Carolina, where the five-time major champion is looking for his first win in 17 consecutive appearances at the event.
The 50-year-old has always played well there, though, finishing in the top five in half of his 16 previous starts at the tournament.
Lee Kyoung-hoon and Keegan Bradley were two shots back after shooting 66s.
Mickelson recorded just one bogey on day one while carding eight birdies, including four of the last five holes.
He won two Champions Tour events last year in his debut season on that circuit, but has not captured a PGA Tour title since winning at Pebble Beach in February 2019.
Mickelson's last opening-round lead or co-lead came three weeks prior to that in Palm Springs, but he did not want to put any additional pressure on himself after Thursday's strong start.
"I don't want to jump ahead, I want to play a good round tomorrow," said Mickelson, who recorded his lowest score on Tour since a 63 in the second round of the 2020 Travelers Championship. "I have an opportunity to play a course I love with a great pairing.
"I'm playing well and I just want to kind of not get ahead of myself and go play another fun round."
Mickelson, who entered the week ranked number 115 in the world, has 30 career opening-round leads/co-lads – the second most on Tour since 1992.
American star Justin Thomas closed out the first round five shots off the pace, while U.S. Open champion Bryson DeChambeau and 2012 tournament winner Rickie Fowler are a stroke further back.
Former Masters champion Patrick Reed shot a 71 as Xander Schauffele and former world number one Rory McIlroy ended the day one over the card.
McIlroy – winner of the Wells Fargo Championship in 2015 – mixed three bogeys and two birdies on a challenging day for the four-time major champion.
Jon Rahm struggled following his opening-round 76, while defending champion Max Homa's bid for back-to-back titles started with a six-over-par 77.
