Seventh-ranked Day, the Australian star with Filipino roots who won the 2015 PGA and was runner-up past year, parred the final hole with help from electronic scoreboard lights to fire a five-under par 66 and stand third on six-under 136, two behind co-leaders Hideki Matsuyama and Kevin Kisner.
Despite his positive demeanor, Stroud admits he did get frustrated at times playing golf in the shadows of others like Tiger Woods, Phil Mickelson and Rory McIlroy. For that matter, the 11 guys in the field who have won a PGA Championship in this century were a combined 68-over par.
Consider that Spieth's way of saying he'll likely have to wait another year to complete the career Grand Slam. "I feel so lucky and so privileged to play on a course like this".
He said in 1999 that he wouldn't return to the U.S. Open and had "had it with the USGA and the way they run their tournaments" after he swatted a moving ball with his putter on No. 8 in his final round at Pinehurst No. 2, taking an 11 on the hole and signing for an 81.
Splendid run: Hideki Matsuyama took advantage of greens softened by an afternoon storm to reel off five birdies on a six-hole stretch.
"Eagling seven and having three birdies after that was nice", Day said.
"I had to catch my breath for a second a few times", he said. Birdies at seven and eight banished those fears, but the result was still another one over par 72.
Spieth was hoping to become the youngest player to win all four majors.
Drunk American tourist's Nazi salute sparks German punch-up
He was punched by a passer by, who then fled the scene and is being sought by police for causing bodily harm. The tourist was identified only as a 41-year-old American man who was "severely drunk", according to police.
"Didn't do anything great today but I didn't do anything bad".
Hideki Matsuyama made only one birdie and wasted two good scoring chances on the back nine.
Kisner, who is seeking his first major championship victory, has not fared well in the game's biggest events and is keen for that to change this week.
"I've played mini-tours, learned how to win there", Kisner said. I have to hit my tee ball where I'm trying to look, and if I don't, I have to find a way to get the ball in the hole the fastest.
Quail Hollow looked vulnerable for the first time in the week. I found myself in the left rough off the tee and things did not go too well and off the third shot I went into right rough and reached green in four and two-putted. "All I'm going to do is I'm going to do this every day". I love this game. It's that type of golf course where you can easily make bogeys.
The South Carolina native then saw his approach to the 18th bounce off a bridge spanning the creek which runs the length of the hole, but he was able to salvage a bogey from a hard lie in the thick rough.
I had a bit of shaky start with a bogey on 10th, a par-5 and that was a disappointment, as you don't want to let go of the par-5s and certainly not drop a shot there. "But I've got to play well in them is the thing".
