Bye for now

Andy Murray is off for some well-earned rest.

I'm off for a sarnie.

See you back here tomorrow for some women's semi-final action.

That break down thusly:

Serena Williams or Simona Halep v Karolina Pliskova 

and 

Caroline Wozniacki v Angelique Kerber

Keep an eye on the website for live scores from Stan Wawrinka v Juan Martin del Potro.

Laters.

Nishikori 1-6 6-4 4-6 6-1 7-5 Murray

Some quotes from Andy Murray's news conference. He is immediately asked about the gong noise from the speakers, which disrupted him when he had a break point in the fourth set.

"When we stopped the point at break point at the beginning of the fourth set it was the fourth time it had happened in the match and the first time we had stopped the point," says Murray.

"I didn't play a good game after I got up from the change of ends, but after that there was a lot of time and I had a lot of game points in the 4-1 game. I lost my serve a couple of times when I was up in the game. That was the difference.

"It is different serving under the roof. It slows the conditions down and becomes easier to return. You have delays in matches and that is not good for television. You want to watch the match without any breaks, but you want to complete as many matches as possible outdoors.

"Under the roof he was able to dictate more of the points and was playing closer to the baseline than me."

Murray out of US Open

Andy Murray has been speaking to the media after his defeat.

He is fairly philosophical and it sounds like he feels the closing of the roof rather than the backfiring speakers were the bigger factor in his defeat.

Full quotes to come.

Semi-final line-up

So this is how your semi-final line-up is looking:

Novak Djokovic v Gael Monfils

Stan Wawrinka or Juan Martin del Potro v Kei Nishikori

Thanks to a withdrawal and two retirements, Novak Djokovic has spent just six hours and 26 minutes on court across his five matches.

By contrast, Nishikori was on court almost four hours tonight alone.

'Strategically smart'

Nishikori 1-6 6-4 4-6 6-1 7-5 Murray

Wow what a great performance from @keinishikori. Strategically smart tennis and mental toughness gets him into #USOpen semi final. Congrats!

Disappointing loss for #Murray with poor serving & mental lapses. Can't always play ones best. But credit to #Nishikori for taking advantage

Gong!

Andy Murray was two sets to one up and was halfway through a point which, had he won, would have moved him a break up in the fourth, when a hugh gonging noise forced the umpire to replay the point.

Murray failed to break when play resumed and was broken himself in the very next game.

So what was the cause?

The United States Tennis Association have released a statement blaming a malfunction in the "digital audio sound processors" in the Arthur Ashe arena.

I'm sure Andy Murray will have some "feedback" for them on that one.

USTA issues statement on recurring gonging sound during matches: #USOpen

Now the Murray/Nishikori match was just what the US Open is all about-- and the fans needed to see-- guts and determination from both!!!!

Nishikori 1-6 6-4 4-6 6-1 7-5 Murray

#Nishikori massive win. From 2 sets to one down he beats #Murray 7-5 in 5th. Andy has more days than he wanted before Davis Cup.

Serve stats

Andy Murray managed only a 55% hit-rate with his first serve and won only 39% of points behind his second serve.

That was the spoiler that prevented the world number two taking flight.

Nishikori was reading his second serve like the Gruffalo by the end of the match. 

"It was too exciting on the court"

Kei Nishikori speaking on court: "It was too exciting on the court, but I tried to stay calm. In the beginning I didn't start well, he has a great return, but I finished well. The rain delay helped me to change tactics. I tried to hit a few more drop-shots than usual today and it worked really well today.

"I have great memories of this place and this is a great chance for me in the semi-finals."

Andy Murray sends a forehand streaking wide to spark a bout of gripping and grimacing from the Scot.

Fifteen-all.

The murmur and burble of the crowd is in Murray's ear as he prepares to serve. The umpire issues a warning to the public.

This is where you have to erase all pain from the brain. You can't think how much your legs hurt or how sore your neck is. It is all desire from now on.

I feared for Nishikori's psyche as he fussily picked fluff of a ball before his opening serve. I needn't.

Andy Murray drifts successive returns long over the baseline to hand Kei Nishikori a pass straight to 30-0.

A dreamy lob over the top of the Scot brings up 40-0.

And Nishikori's brute force seals the game on the next.

Henry Monk: I think it shows why Murray is a grand slam winner by showing grit to get himself to 5-4 first.

*Nishikori 1-6 6-4 4-6 6-1 4-5 Murray

Kei Nishikori's touch at the net was that of a brain surgeon for the previous three sets.

Suddenly it is like he is gripping his racquet through boxing gloves.

A clumsy cuff over the baseline gives Murray 30-15.

The Briton seals his hold with a string-stretching ace into the apex of the service box.

Nishikori to serve to stay in the match next. And with a changeover to stew on that fact...

So many twist and turns that we have ended right back where we started.

Two men and nothing between them.

That volley at 40-30 was so easy and so regulation for Nishikori. That could cost him.

Murray takes Nishikori to deuce

*Nishikori 1-6 6-4 4-6 6-1 4-3 Murray

Kei Nishikori's turn to feel the pain.

He winces as his muscles tighten and he nets a midcourt forehand for 40-30.

A gimme of a forehand volley at the net. He has been making harder shots stick all night. 

Into the net! Japanese fans cover their eyes.

Deuce.

Murray is trying to end the points too quickly. He needs to think of what got him into such a big lead in the early part of the match.

Kei Nishikori leans out wide and slaps a pearl of a return winner for 30-15.

He scurries and fetches, filling Arthur Ashe with the smell of burning shoe rubber in the next rally.

Basically he is Murray-ing, Murray.

A forehand cushion into open court and it is 40-30.

The Japanese clambers into another return down the line. Murray rooted and watching, along with tens of thousands of others in the stands.

A mite long. Murray holds. Just.

It is breaking one of the first rules of tennis. Do not break your concentration and talk to yourself between the first and second serves.

Andy Murray's second double fault of the match sure chooses its moments.

It's ugly head rears up to hand Kei Nishikori a break point.

Nishikori converts and British fans' stomachs lurch.

Murray down and three Nishikori service holds away from being out.

This is boiling down to the smallest fractions in the crucible of a fifth set. 

Kei Nishikori slips a sublime forehand slice into the front court for a drop-shot winner and a toehold at 30-15.

He loads up big on the forehand side on the next point and is only a whisker away. 40-15 Murray.

But a crunched return down the line and another winner and we are into deuce-town.

Nishikori long on the second break point!

Decider level!

And, perhaps most enticingly, the Nishikori forehand is coughing and spluttering.

This is high-octane, 80%-proof stuff. The sort of legal high that comes with government approval.

This is a chance. Kei Nishikori presses a forehand a few inches too long for 0-30.

We are close to full Murray meltdown.

He pulls his cap down over his eyes as he ships an early point.

His team get a tongue-lashing as he drifts to 30-30.

The world number two is teetering.

But he pulls back on the joystick just in time to avert full tailspin. A forehand rolled away to hold the game from the Scot.

This is a closer to watch from behind the sofa. Nerve-shredding, cuticle-chewing stuff.
