And so we bring this Sportsday to a close, and what a day it turned out to be.

James Ward produced a quite stunning comeback to beat John Isner 15-13 in the fifth set and give Great Britain a 2-0 Davis Cup lead over the United States.

Hope you enjoyed it. Let's leave you with a photo of the man of the moment.

James Ward, you beauty. If I had a cap, I'd doff it. Goodnight.

What a day of tennis that has been.

And who'd have thought Englishman Ward would end up getting a bigger roar in Glasgow than Andy Murray? Amazing.

Woof: James ward - HERO!

Ben Roach: There was only one song those Scots could play after that epic... More of The Proclaimers!

RacketlonNews: Every British racket sports player stand up and salute James Ward. From two sets to love down to win 15-13 in the 5th set.

Kenny Simpson: WHAT. AN. EFFORT.

GB captain Leon Smith looks almost as shattered as James ward.

"He deserves all the plaudits he gets after that match," said Smith.

"It was so gutsy. he kept fighting, even if he was 40-0 down on Isner's serve and that paid off in the key moments.

"I can barely speak. I've almost lost my voice.

"But it's really tough for the USA now at two matches down. But they have Jim Courier as captain and he will not let them go down without a fight."

James Ward is interviewed on court. He looks emotional. The crowd are cheering wildly.

"I'd prefer it if I had less five set matches... I don't know what to say," he says.

"This is by far the best atmosphere I've ever been involved in and thank you very much to all the crowd."

He added: "It was difficult. I had a lot of chances in the last set. It was an unbelievable match."

James Ward has just come from two sets down to beat the best player in the United States.

What a hero. He goes wild, then hugs Andy Murray for a long time, the kind of time you'd hug your partner for on Valentine's Day. Hope Kim isn't jealous.

But why not. That was brilliant. Four hours and 52 minutes. One of the best Davis Cup comebacks of all time? Very possibly.

Game number 28 of the fifth set.

And Ward starts well, moving to 0-30. Isner suddenly looks spent.

And the American slams a forehand wide. 0-40. The crowd go wild. Three matchpoints.

He only needs one. Get in son. Ward has done it. Pop the champagne.

This man is loving it.

Danger for Ward as he slips to 0-30 behind on serve.

A tense hush falls around the Glasgow crowd. Two greatpoints and he's back to 30-30. Cue pandemonium again.

Andy Murray is even feeling the heat. He's removed that big sweater, the one that made it look like he was outside trying to make his way home after work on a freezing winter's night, revealing a blue T-shirt. Very fetching.

Ward goes 40-30 ahead . A big serve and he holds. Great comeback that from an awkward position. 14-13. Phew!

Ladies and gentleman, we've just broken a record.

Four hours, 49 minutes - makes it the longest ever World Group singles match at the Davis Cup.

On the court, it's 13-13. Ward serving.

Nicola Jade: Four and 3/4 hours in and I am knackered just watching James Ward and John Isner... Unbelievable tennis!

Jamie Gardner: What is it with Isner and 5th set marathons!

Dan Turner: Whatever the result, this is a heroic performance by James Ward.

Here. here Dan. Though let's make sure it's not another case of plucky Brit loser eh?

Well, what a game that was. Ward wins it to love to go 13-12.

Both men return to their seats to take a well-earned two-minute breather.

Isner looks like he needs the break more but remember he's been here before.

Back at Wimbledon in 2010, the American overcome Nicolas Mahut 70-68 in the deciding set of an unforgettable first-round encounter.

Isner outlasted Frenchman Mahut to win 6-4 3-6 6-7 (7-9) 7-6 (7-3) 70-68 in the longest match in history, taking 11 hours and five minutes over three days.

Hopefully this one won't take quite as long, especially as I'm meant to be meeting a pal of mine in half an hour for a pint.

Cameron Johnson: My mate has came round to house and suddenly we're captivated by Davis Cup match. Come on Ward!

Sniff of a chance at 0-30 on the Isner serve but the American, sensing danger, hits back to 40-30. Great forehand from Ward and it's deuce. But a weak end to the game, two Ward mistakes, sees Isner take it. 12-12.

The GB team applaud their man, and on we go.

Piers Newbery
BBC Sport at Emirates Arena, Glasgow

"Provisions are being horded, transport rearranged, toilets queued for… an epic match in the best traditions of the Davis Cup, and tie could really be on the line as a Ward win would leave the US struggling.

"Credit to Isner, he has produced big serves when it matters, while Ward came through a hugely edgy game to hold for 12-11."

This fifth set has now lasted 89 minutes. That's one hour 29 minutes. After they've already played four sets. How do they do it? I'm shattered after four press-ups at the gym.

Ed Fondue: Andy Murray has just popped out to take part in Wimbledon.

Very good Ed. But don't joke about it. The way things are going it could happen.

Some decent play from Isner during the game, coupled with one or two mistakes from Ward - means the American takes it deuce. That hasn't happened often this set.

Alarm bells ring. And they get even louder as Isner moves to advantage.

The American has suddenly raised his game and Ward's level has just dropped a fraction. Two breakpoints, both saved by Ward. Gutsy stuff, but then you expect gutsy from a lad who has come back from two sets down.

He takes the game. Brillaint stuff. 12-11. Everyone keeping up? Good.

Rhosyn Morgan-Davies: The noise from the crowd is incredible! They're like football fans! Wish I was there.

Kenny Simpson: This is getting insane!
