He at least is starting to see signs of it coming together with an 8-under 63 on Friday in the Wells Fargo Championship, matching his career-low score on the PGA Tour and giving him a one-shot lead going into the weekend at Quail Hollow. Then there's two-time Wells Fargo victor Rory McIlroy alone in fifth at 9-under after a 3-under 68. It appeared McIlroy was building some momentum, but the second horn sounded suspending play again as he was lining up his birdie putt and he had to go all the way back to the clubhouse again. McIlroy was less than 50 feet away from the pin in two, but, remarkably, took five to get down.
But McIlroy pulled it together, making birdie on the short par-4 14th hole and the reachable par-5 15th hole to claw back to within two shots of the leaders, none of whom could separate themselves from the pack coming down the stretch at Quail Hollow's hard three closing holes called the Green Mile.
Homa's win was delayed by inclement weather.
Dufner, the second-round leader, had back-to-back bogeys late in his round.
Dufner made consecutive bogeys during the storm delays, answered with consecutive birdies and joined them at the top with a 71.
Pat Perez had a bogey-free 66 through two rain delays and was one shot behind.
His nightmare began when three-putted for par at the seventh, failed to birdie the driveable eighth after a poor pitch and then three-putted the ninth from 50 feet to turn five strokes behind Dahmen and Homa on eight under.
"I'm not really trying to be mediocre", he said.
"One of the holes today I felt I was going to throw up but my hands felt unbelievable on the club, felt as solid as a rock and golf swing and putting stroke were as good as I could have imagined. I'm usually good with words, but I don't think I have any".
"I didn't beat myself today", said Dahmen, who could hardly have been happier for the victor and was looking forward to a big night on the town. He, too, gets into the PGA Championship in two weeks at Bethpage Black and gets an invite into the 2020 Masters and Players Championship. "I like how I played, I like my chances and I like where I'm standing after three days".
"Played first six holes well today, pretty steady and then the three-putt on seven derailed any momentum I had", the Northern Irishman told reporters.
"I told myself I'm right in the thick of the tournament but you have to stay patient and nearly let it come to you rather than try to chase it", McIlroy said about The Players Championship.
Three more birdies and just one dropped shot followed on the back nine as McIlroy headed back to the clubhouse on nine under.
Homa always had the talent, winning the NCAA title at Cal with a three-shot victory over Jon Rahm.
Two-times Quail Hollow champion Rory McIlroy's expected charge never got off the launch pad.
