CHARLOTTE – Unheralded Kevin Kisner fired a one-over par 72 Saturday and clung to a one-stroke lead over fellow American Chris Stroud and Japan's Hideki Matsuyama after the third round of the PGA Championship.
On a wild day at formidable Quail Hollow, nearly every player was humbled by the 7,600-yard layout, Australia's Jason Day stumbling to a 77 with a closing quadruple bogey.
Kisner, who won his second US PGA title three months ago at Colonial, stood on seven-under 206 after 54 holes despite a double-bogey disaster at 16 when his approach found the water and a bogey at 18 when only a lucky bounce off a rock saved him from another watery grave.
Stroud, who won last week in Reno to claim the final berth in the PGA field, closed bogey-bogey for a 71 to kept him one back.
Matsuyama, trying to become the first Japanese man to win a major title, fired a 73 to share second on 207. He answered an opening bogey with a birdie at the par-5 seventh but was undone by bogeys at 12 and the par-3 13th.
South Africa's Louis Oosthuizen, the 2010 British Open champion and a three-time major runner-up, shared fourth with American Justin Thomas on 208 with American Grayson Murray another stroke back.
