Well, how is he going to fare tomorrow with his one-shot lead? Is world number three Hideki Matsuyama, one shot back in a share of second, his biggest challenge or will someone come from pack?

Join us for the final instalment. They are back in pairs tomorrow and it will be Kisner and Chris Stroud last out at 2.45pm local time, 19:45 BST. It's going to be another late one. Cheerio for now.

Leader Kevin Kisner on the long wait he had at the 18th while Jason Day was making an eight: "I was pretty perplexed about that chip shot I had, rather than watching Jason I was working out how I was going to take five from there. I don't want to be there tomorrow."

Kevin Kisner: "There's no real need to show emotion but I'll show plenty of emotion if I win tomorrow. It's a dream to win a major, the way my game has progressed I like my chances. I'm sure a lot of my buddies will be making their way over tomorrow but the great thing is when I get home golf is over and that's what I love about them."

Kevin Kisner: "At the 18th I didn't do enough scouting, I never thought they were going to put the flag there. I tried to go right at it with a seven iron and it was a stupid play, but it puts a little fire in me for tomorrow."

Some thoughts from leader Kevin Kisner on the pace of play: "It was super hot and standing around in 105 heat index is not a lot of fun. I'm pretty used to slow play, you watch us every week."

Casey is still the highest placed British player, however. Big Bristolian Chris Wood is one over and Wiltshire's Jordan Smith, who eagled the 14th after driving into the heart of the green at the par four as you can see below, is plus two after a round of 70.

The Green Mile has caused some consternation today. Paul Casey was another to suffer, dropping four shots in those final three holes to drop to level par for the Championship. That's level with Jason Day and they could compare horror stories if they are paired together for the final round tomorrow.

Safely in for Kisner and that's it for the third round. The 33-year-old dropped three shots in those three Green Mile holes but he will take a one-shot lead into the final round in his quest for a first major title.

A third round of 73 for Hideki Matsuyama, who still has that tag of "bidding to become the first Japanese player to win a major."

It's a quadruple bogey EIGHT for Day. He can still smile though, but it's Jack Nicholson in the Shining-esque (another Stephen King reference eh?) and the Australian slips to level par for the Championship.

My word that was quick, he hardly seemed to touch that in the fading light as the sun disappears behind the large Quail Hollow clubhouse. Neatly judged and he will be inside three feet for his par. Day has not finished yet, people are losing count of how many he has taken.

Kisner plays out away from the danger and to the back of the green, he is going to be content with a bogey five here, which will be enough to retain the lead. He will be doing well to get down in two though, it is 46 feet away.

After some lengthy jiggery pokery behind the bushes, Day and a rules official decide where he should drop the ball but his fourth shot still does not find the fairway. He hacks out of the rough and is short of the green in five at the par four.

That was a crazy choice for a second shot from Day. He is really shooting himself in the foot. I can't believe a player of his pedigree did that.

It's all happening on the 18th fairway. The crowd were probably expecting Day to just pitch out into the fairway but he tried to draw one from the edge of the cart path, scattering the spectators in the process. His club has clattered into the tree and the ball is nowhere to be seen.

Even mild-mannered leader Kisner is feeling the pressure, his approach drifting left, bouncing high over a rock in the stream and coming to rest in the rough.

Day is in the pine straw a couple of feet behind the trunk of a huge tree. We could have a delay while he arranges the crowd, but hopefully not of Jordan Spieth proportions. In the distance there is a rainbow. The last thing we need is a thunderstorm with the final group so close to finishing.

It's back to back bogeys for Stroud as the par putt touches the left edge yet doesn't drop. He finishes with a 71 and a six under total, which currently shares second, two behind Kisner. Oosthuizen finishes five under and the third member of the group, Francesco Molinari, is two under.

Stroud guides one towards the cup at the last with that unusual broomhandle putter. It looked good from 20-plus feet but it has raced six feet past.

Kisner just shaved the right edge. He looks absolutely shattered. I think the intensity has got to him, but he has got away with a par.

There has been little show of emotion from Kisner today but he puts his hand over his eyes as a good looking birdie putt brushes the edge of the cup but stays above ground. It is a par three for the leader. Day's eventful round continues when he fails to hole down the hill from eight feet for par and he is four adrift again.

That's a sorry way to finish for Fowler, missing on the left from inside three feet for a 73 that will leave him on one under for the Championship. Playing partner and good pal Justin Thomas returns a 69 for a five under total
