CHARLOTTE, N.C. -- On some of the fastest, most frightening and, at times, frustrating greens the PGA Championship has ever seen, Kevin Kisner and Thorbjorn Olesen emerged with a share of the lead Thursday at 4-under 67, the highest score to lead this major after the opening round in seven years.
For all the talk about this 7,600-yard course favoring the big hitters, the shortest club in the bag turned out to be just as valuable.
"Any time you have a putt down grain, downhill ... we just tap it and hope it stops by the hole," Jon Rahm said after a 70.
U.S. Open champion Brooks Koepka led five players at 68. Koepka missed a half-dozen putts from 12 feet or closer, and while it looked as though he hit the ball well enough to go low at Quail Hollow, he wasn't the least bit frustrated.
"It's going to test your patience one way or another," Koepka said. "That's just a major. You've got to stay patient. You can't make doubles out here. That's the big thing. Make sure the worst score you make is a bogey and give yourself a couple of good chances on the easier holes."
That's the way Kisner approached it.
It helps that he grew up in the South and loves Bermuda greens. Given the size of Quail Hollow, Kisner drew up a simple plan. He identified four or five holes where he could make birdie, and he played for par everywhere else.
"I birdied them all today," Kisner said. "Make a lot of pars, and get to a par 5 or one of those short par 4s, I can do my wedge game and get it to 10 or 12 feet. That's my plan. Other than that, I'm playing for par."
The 18th was not one of the birdie holes he had in mind, especially with his ball nestled in the Bermuda rough 205 yards from the pin. Kisner thought the grass was thin enough behind the ball to get a 5-iron on it, and from there it was a matter of judging how much it would bounce. It ran up to the green about 20 feet away, and he used that rhythmic putting stroke to trickle it into the cup.
Olesen picked up birdies on most of the same holes, and he finished with a 30-foot birdie that also sounded like an accident.
"It was a little bit of a safe shot into the green," he said. "That's what can happen on this golf course. When you play safe into the greens, you give yourself very tricky putts, like the one I had -- downhill, left to right. It was very, very fast. But it was just a very good roll. So it was nice to see that one drop."
Jordan Spieth, playing in the only major keeping him from the career Grand Slam, didn't make a putt longer than 5 feet -- that one was for par -- and was coming off a pair of three-putt bogeys from long range when he steadied himself with a pair of perfectly executed birdies for a 72 that left him five shots behind and very much in the game.
Rickie Fowler made plenty of birdies, and he needed them to offset his triple-bogey on the sixth hole. He finished two shots back at 69.
Rory McIlroy, the betting favorite coming into the week because of his two victories at Quail Hollow, was motoring along just fine when he birdied the 10th hole to reach 2 under, just two shots behind. One swing changed everything. He hooked his tee shot into the water on the reachable par-4 14th, had to drop in nasty rough and missed a short putt to make double-bogey. He failed to birdie the par-5 15th and closed with three pars for a 72.
Quail Hollow played to an average score of 74.7, making the PGA Championship look like the toughest test of the year in the majors. The PGA Championship typically features good scoring because it's held in August when water has to be kept on the greens to keep them from dying.
Phil Mickelson failed to make a single birdie -- the second straight major that has happened -- and shot a 79, his worst score ever in the PGA Championship. Ernie Els, who might be playing his final PGA, matched his worst score in the championship with an 80. He also shot 80 when he was 22, playing his first PGA Championship at Bellerive in 1992.
