"That's one of the craziest decisions I have ever seen a professional make, that second shot", said Faldo.
Matsuyama, who started the day with a two shot lead, struggled with three bogeys against a single birdie for a 54-hole total of 6-under 207 at Quail Hollow Club, sitting in a tie for second place with American Chris Stroud. Stroud, ranked 203rd, resumed in the greenside rough at the par-4 fifth hole, chipped to seven feet and sank the par putt.
After sinking a 22-foot par putt at the ninth, Matsuyama began his birdie charge with a 12-foot putt at the par-4 12th and six-footers at the par-3 13th and par-4 14th.
While Olesen and Kisner shared the lead with 67 each, there were five players at three-under 68 in Tied-3rd.
The tournaments Matsuyama has won this season are not lighter ones, winning two World Golf Championships with the best fields in golf, and the Waste Management Phoenix Open, which always has a solid field and huge galleries.
Kisner and Matsuyama, both leading a major for the first time, were at 8-under 134.
'No need to worry' about swine flu
In Yangon, 73 out of 256 hospital patients are found to be infected with H1N1 and the death toll reached seven. "I will get it confirmed", he said.
"I'm hitting the ball really nice and things are going my way. However, I'm happy to be just one stroke back and still have a chance", he said. "He's working hard. And I feel like he's the hardest worker out here right now, just because he wants to win", said Day. "After playing practice rounds I felt there was a decent one out there". Par at the last, and he would be just three back trying to win his second PGA Championship in the last three years. "I hope he slows down and gives the rest of us a chance". He'll need a herculean effort to leapfrog the 11 players in front of him and hoist his first major championship trophy.
"The ball is coming out of the gun right where I'm looking at it", Kisner said. "Hitting fairways are key".
Austria's Bernd Wiesberger would have made the cut four over par with a birdie on his final hole, but bogeyed it instead to miss out by a shot and end his streak of 26 consecutive events earning world ranking points. He closed with back-to-back pars.
The 33-year-old Kisner showed a sublime touch on the final green to escape with only a bogey five for a one-over 72 and seven-under 206 as he bids for his first major title. DeLaet two-shot the par-three for a birdie, shaving a stroke.
"Anything under 71 today is a good score", McIlroy said.
