As the PGA Tour's two biggest stars have been stymied by the course this weekend, the top of the leaderboard at the PGA Championship is bracing itself for a busy day on Sunday.
He leads at eight under with Kevin Kisner, who had a second successive 67.
Both made birdie on the 18th hole with lengthy putts that trickled - and trickled - into the cup. "I was defensive and still had to make 4- to 5-footers for par on a couple of them". Casey shot a 1-under 70 on Friday and sits at -3 for the tournament, five shots out of the lead. "Just said, 'OK, I'll bounce it up the cart path and see where this goes". "If we look historically back on my career, I think I will play this tournament worse than the other three majors just in the way that it's set up".
Spieth wasn't alone in his struggles.
The Japanese rescued par at the ninth hole with a 22-foot putt, then began his birdie charge with a 12-foot putt at the par-four 12th and six-footers at the par-three 13th and par-four 14th before a storm halted play. He also shot 72.
Players making a move up included Rickie Fowler (two-under through 14) and An Beyong-hun (3-under through 15).
Par-5, 546-yard No. 7: It's the shortest par-5 on the course, and most thrived.
U.S. Open champion Brooks Koepka led five players at 68.
Quail Hollow underwent a number of changes from its annual Wells Fargo Championship layout.
"Because they were the two things that were missing pretty much the whole year is my driving and my putting, and being able to combine that today, just felt like the old days, which is only last year".
"And you're playing your ass off to get that".
That's the way Kisner approached it. He loves Bermuda, the grass now in place at Quail Hollow, and his confidence soars when he's hitting it well.
Day nearly landed a rare albatross on the par-five seventh hole and the resultant kick-in eagle kickstarted a run of five birdies in the next seven holes - either side of a weather delay - to enable a five-under-par round of 66 to race to six under in total. "And the worries that I had about my swing showed up today in the way I played". "Even if they didn't do anything else with the golf course and just changed it to full Bermuda like it is now, all of a sudden it makes the golf course two shots more hard". I could and should have finished at least in the under-par zone.
