Not a blade of grass is free on Henman Hill as Murray fans without a Centre Court ticket squeeze in to watch on the big screen.

A collective groan went up as Tsitsipas won that tie-break.

Imagine the limbs if Murray can get this done in five…

We could probably just skip to the match tie-break now, couldn't we?

But where on earth would the fun be in that.

Stefanos Tsitsipas looks to wrap up a swift love hold of his own, but Murray checks his progress with a cheeky lob. The Greek simply watches it float over his head, saving his energy before settling things on very the next point.

First set secured for the third seeds Joe Salisbury and Rajeev Ram on court 18.

The duo were pushed to a tie-break by Tallon Griekspoor and Bart Stevens but they have got their reward.

You can't take your eye off this match. Just as you think you know the way it is going there's another twist as Chris Eubanks breaks back.

Some great tennis sees him get three break points and although Cameron Norrie saves the first, the Brit puts a return into the net from up close and we are back on serve.

Just what Murray needed to reset, and that is just the service game he needed to do that, after being a set away from victory.

The perfect response to losing a set?

Win the next game to love. Andy Murray is straight back down to business on Centre Court.

A swift service game for Chris Eubanks and he holds, but Cameron Norrie still has the break.

Well, that's pooped the party.

Tsitsipas is like the kid who's gone around and popped all the balloons.

Other than about a dozen Greeks in Tsitsipas's box - and one Spanish female tennis player - the rest of Centre Court stayed in their seats when Murray lost the set.

How is everyone holding up?

We sort of knew this would go the distance, didn't we?

A thrilling match continues on beyond the four-hour mark.

Andy Murray gets us back under way...

A fierce serve has too much for Chris Eubanks and Cameron Norrie lets out another roar as the return goes long. A hugely important hold and Norrie leads 4-2.

Chris Eubanks is making mistakes now and is a little careless with a shot at 30-15 down as too much power sends it wide.

He hangs in there to get back to deuce before another winner gives him the opportunity for an immediate break. Cameron Norrie saves it, and then another one, and a third before clipping a wonderful shot just over the net and put him on the cusp of an important hold.

There it is. The road to round three will be a long one.

You can't argue that Stefanos Tsitsipas played that tie-break near-perfectly.

He needed to, and he has his reward.

We're going to a fifth set!

Stefanos Tsitsipas continues with a steely focus, despite the distractions from all corners of the arena.

Two solid serves. Three set points.

It's mesmerising stuff.

The crowd can't contain themselves as a 30-shot rally rumbles on, but it's Stefanos Tsitsipas who comes out on top, forcing the issue and closing in to volley for the first mini-break at 4-3.

That could be a huge moment.

Huge opportunity for Cameron Norrie here as he responds to everything Chris Eubanks can throw at him and he has three break points.

The crowd are behind him and Eubanks, who started this set so confidently, looks worried. He gives himself a few words of encouragement before his first serve at 40-0 down but sends it long before then putting a return on his second serve into the net.

Norrie has the break!

A shout of frustration from Andy Murray, who can't get hold of a Tsitsipas serve as the Greek edges ahead at 3-2.

Both players remain so strong on serve, but something has got to give.

Murray levels the tie-break before the change of ends and is greeted back to the court by huge cheers of encouragement.

Ooh. Just. Murray gets fortunate as a shot clips the net cord but kindly falls in, allowing him to follow up with a volley and take his second point on serve.

It's tense out there.

As we saw last night, that Tsitsipas forehand doesn't half pack a punch.

He calls upon it again here to get up and running in the tie-break.

A big game for Cameron Norrie as he saves a break point and then turns it round to seal the hold.

The Brit lets out a roar, he knows how important that could prove to be.
