British duo Joshua Paris and Eden Silva are out of the mixed doubles.

The unseeded pairing fell to a straight-set 7-6 (7-5) 6-3 defeat against Czech-Dutch pairing Katerina Siniakova and Sem Verbeek out on court three.

There was just one break of serve in the encounter but, when the big moments came, it was Siniakova and Verbeek who came out on top.

They will face either eighth seeds Mate Pavic and Timea Babos or unseeded pairing Jackson Withrow and Irina Khromacheva in the semi-finals.

Break consolidated. Alex de Minaur is halfway to forcing a fifth set.

It's pretty comfortable for the 11th seed as well. Even when a double fault gives Novak Djokovic a sniff at 40-30, he finds a good second serve on the next point and goes on to hold.

After Flavio Cobolli's win over Marin Cilic earlier - and with world number one Jannik Sinner still to come later - we could have three Italian players into a men's Grand Slam singles quarter-final for the first time ever.

Still plenty of work for Lorenzo Sonego to complete the second leg of that trifecta, of course.

Ben Shelton reminds him of that, holding serve to begin set two on court one, aided by a wonderful job just inside the baseline.

What did I say about Novak Djokovic starting to dominate?

Well, you can ignore that! Alex de Minaur breaks first in the fourth set - and does so comfortably.

He gets the better of an entertaining exchange at the net, brings up three break points and gets the second of them when Djokovic put a tame backhand into the net.

My word, that was some game and end to the first set.

Ben Shelton really came in to that, earning himself two break points after getting to grips with the Lorenzo Sonego serve.

But the Italian saved both, and served out to take a deserved lead in this match.

The American is now getting a warning from the umpire about the time he's taking to prepare for Sonego's serve but he's not happy with the warning - arguing that the Italian is waiting until the moment to serve every time.

This huge serve from both players has been something to witness, but Sonego has been serving particularly well. Shelton hasn't got near to him.

This is probably Sonego's best performance in an individual match, but even that might not be enough.

There has never been a player more technically proficient than Novak Djokovic.

If you're going to train some young kids, get them to look at his groundstrokes and pretty much copy everything that he does.

They could try, but doing it is the hard part.

Crucial hold for Alex de Minaur to start the fourth set.

Novak Djokovic is starting to dominate and dictate the rallies but De Minaur clings on.

The Australian has to save a break point but even then, the pressure exerted by Djokovic is clear, as - with the court at his mercy - De Minaur gets to the net whips a forehand that only just drops on the baseline.

He wanted to give the Serb absolutely no chance, which he did, I suppose.

Brilliant deep serve from 19th seed Liudmila Samsonova saves a break point against Spain's Jessica Bouzas Maneiro on court two.

That's a big hold for Samsonova after she pinched a tight first set.

That pressure is going to be right there. If he has that opportunity to get to the final here he is going to be really tight.

We have already witnessed it when he was trying to reach his 100th title, how long did that take him? He has been on 24 Grand Slams for quite a period of time and I think it will be a very nervous Djokovic. It is a really tough, emotional moment.

It will be like a whole new opponent that he has to play - picking up number 25.

How in the world did De Minaur miss that shot? He gave set point to the Serb.

What a sensational way to seal the third set.

De Minaur gave everything he could to that last point. It was just a slight mistake on the backhand which gave Novak the forehand and allowed him to dictate.

Novak Djokovic leads after another superb rally.

He's come from a set down and is now just a set away from another Wimbledon quarter-final.

There was a chance for Alex de Minaur at 30-30 but he dumped a backhand into the net. A costly unforced error.

"Novak! Novak! Novak," chant the crowd before set point.

It's a long point but Djokovic gradually takes control, moving De Minaur one way then the other before coming into the net to finish it.

What has De Minaur got left?

Liudmila Samsonova has taken the opening set against Jessica Bouzas Maneiro out on court two.

The 19th seed claimed an important break of serve at 6-5 up to secure a healthy one-set advantage in the last-16 match, leaving Spain's Bouzas Maneiro bitterly disappointed after a strong first-set showing.

There were multiple breaks of serve in that first set, so expect more drama to unfold in this one!

This is a serving clinic from Lorenzo Sonego right now.

His first-serve percentage is at 82% after four service games - meaning he's failed with just two attempts so far.

Shelton, by contrast, is getting just 35% of his first serves in so far.

De Minaur is playing top tennis today. The best I have seen him play in a long time. His forehand has been a problem at times and he is not able to finish points. But that's just because the game is getting tight now.

Djokovic has been making De Minaur run more and more. He finally has a chance to go ahead in this set.

A painful loss of serve for De Minaur.

Novak Djokovic will serve for the third set!

The Serb was furious with himself for attempting a drop shot at 0-30 when he really had no need to.

That ball ended up in the net but Alex de Minaur was not able to come back.

At 30-40, he fires a forehand wide and Djokovic has the chance to go up two sets to one.

In the context of this match, with how this has been going for both players, the outcome of this third set really does feel crucial.

Alex de Minaur has done very little wrong and he absolutely must believe this is there for the taking.

In this tight set, the crowd, the majority of whom just want to see a brilliant match continue for as long as possible, are strongly backing whoever needs them most at any particular moment.

Sonego is playing great percentage tennis right now. He is playing hot and having no trouble with the Shelton serve. This is a real problem for Shelton early on.

Just as Alex de Minaur might think he's got a chance at 30-30, Novak Djokovic's serve comes up trumps.

He goes out to De Minaur's forehand side and it's all the Australian can do to get a racquet on it, then nails a ace down the T to hold.

Who will blink first in this third set?
