Playing the final group, Chris Stroud double bogied 16 and bogied the 17th and 18th holes during the famous green mile at Quail Hallow to slip to 1-under par for the tournament.
It was still a top ten finish for Stroud, who at one point was tied for the lead at 7-under after two birdies on the front nine. Stroud played the back nine in 6-over and after finishing tied for 9th, earned $250,000.
Justin Thomas rallies to win the PGA Championship
CHARLOTTE, N.C. (AP) - Justin Thomas has his first major title after overtaking Kevin Kisner and several others in winning the PGA Championship at Quail Hollow.
The world's 14th-ranked player closed with a 3-under 68 that included four birdies in a six-hole stretch. The run included a dramatic putt on the par-5 10th hole where his ball lingered on the left edge of the cup for about 12 seconds before falling in. He followed that by chipping in from the fringe on No. 13 for another birdie.
Thomas all-but secured his fourth win of the year by sinking a 15-foot birdie putt on the par-3 17th, giving him a three-shot edge. He started the day two shots behind Kisner before finishing 8 under for the tournament.
Louis Oosthuizen , Patrick Reed and Francesco Molinari tied for second at 6 under, though none had a chance to win as they played the 18th. Rickie Fowler and Hideki Matsuyama finished three strokes back. Matsuyama began the round one shot off the lead as he tried to become the first Japanese player to win a major.
Kisner faded at the end, beginning with a three-putt for bogey on 16. That was followed by a birdie miss and a double-bogey for a 3-over 74 that left him four shots back.
Chris Stroud fired a 5-over 76 after entering the round within one shot of Kisner.
