There has been the odd flicker of entertainment in this second set but it's largely been serve dominated.

Alexander Zverev wins another service game to love to inevitably take the second set on Centre Court to a tie-break.

There's a host of famous faces sitting together on Centre Court, making a box of their own.

You've got Doctor Who's Ncuti Gatwa, Chicken Shop Date's Amelia Dimoldenberg and Game of Thrones star Nathalie Emmanuel among a sea of other celebrity names enjoying the tennis.

Taylor Fritz getting encouragement from the crowd as he banks a service game to love with a clever shift of his body to produce a forehand winner.

The American only lost five points on serve in this set. Alexander Zverev has lost just six.

Which way is this set going?

Court One was packed for the end of Alex de Minaur's match with Arthur Fils.

That one ended with fireworks and there was never a good moment to quickly pop out to the loo, or to get some refreshments.

No surprises then that the court is pretty sparsely covered as Yulia Putintseva and Jelena Ostapenko warm up. But we should fill up again soon.

A trickle of applause signals the arrival of Yulia Putintseva and Jelena Ostapenko on court one, which still has its roof closed in anticipation of rain.

This pair have played each other four times previously, winning two each, but it is their first meeting on grass.

Mark: Alex de Minaur was not looking good at the end of his match. It looks like the physios are going to have to work some magic before the quarter-final.

Taylor Fritz pops an energy gel while Alexander Zverev guzzles a drink during the break as the crowd on Centre Court hums.

A pivotal few games coming up.

A large ooh from the Centre Court crowd in that last game as Taylor Fritz makes anyone who has ever picked up a racquet feel much better about their own game with a wild swipe and a complete miss of the ball with an air shot.

A nonchalant, almost dismissive, toss of the spare balls by Alexander Zverev after he wins the eight game of the second set to love. Very little to choose between these two players at the moment.

It looked like Alex de Minaur rolled his ankle in the closing stages. He's asked about it on court but says "he'll be alright."

Court one is emptying after Alex de Minaur's victory as fans head out for refreshments, but they will be back in due course with Yulia Putintseva v Jelena Ostapenko up next.

Kazakhstan's unseeded Putintseva beat top seed Iga Swiatek in the third round and her reward is Latvian 13th seed Ostapenko.

Two-time Wimbledon mixed doubles champion Jamie Murray has teamed up with American Taylor Townsend at this year's Championships.

They are playing their first round match on court two against Colombian Nicolas Barrientos and Japan's Miyu Kato.

The British-American team have won the first set 6-3 and it's on serve in the second set.

David Franks: Re coaching just discussed by BBC tennis team, perhaps a good compromise would be that coaches can use signals any-time but no vocal-instruction, as what they say may unfairly put the opponent off.

A rare double fault from Alexander Zverev, who is playing while wearing a knee support on his left knee, gives Taylor Fritz a glimmer of hope, before some great variety from the German fourth seed.

Zverev produced a lovely cross-court winner and then a deft volley, It has been a match of few chances and even taking his opponent to deuce, but then no further, feels like a missed opportunity for Fritz.

Alexander Zverev double faults at 40-30 in the sixth game to give Taylor Fritz an opening. Deuce.

However, the 6ft 6in German has found a knack of raising his service game when needed so far in this contest, and he clinches the game with consecutive points.

New balls.

Let’s hear from Alex De Minaur who reaches the quarter-finals of Wimbledon for the first time:

Firstly, are you ok?

“I’ll be alright. I’ll find a way. Thank you guys. The atmosphere was unbelievable . I can be proud of myself to be in the quarter-finals of Wimbledon, playing in front of you guys, so thank you.”

What pleased you most about your performance?

"Getting over the finish line. I definitely made it a lot harder than I should have. Happy to get through. Great job mentally to stay with it even though I couldn’t serve at the end. I couldn’t hold my serve, I just backed my returns instead and on to the next."

Next – Rune or Djokovic – both of who you’ve beaten in the past:

"I’m just excited to be in the quarter-finals, have another battle and give myself a shot. One thing you can definitely count on is me going out there, trying my hardest and playing my heart out.

Alexander Zverev is wearing as much gold jewellery round his neck as Mr T (okay, that might be a slight exaggeration...) but it's not weighing the German down at the moment.

Here's how he closed out the first set a little while ago.

Alex de Minaur can barely acknowledge the Court One crowd. He hobbles over to the net to shake Arthur Fil's hand before dropping into his seat.

He and Fils have just played a properly epic match and are both getting a superb reception.

Ah. There is some concern here for the fitness of Alex de Minaur.

The Australian can be seen pulling up as he played that match-winning shot.

He went back over to his chair and was shaking his head in the direction of his coaching box.

Let's see if he has anything to say on that when he is interviewed on court in a moment.

A place in the quarter-finals against either second seed Novak Djokovic or 15th seed Holger Rune awaits.
