What a day for Jack Draper!

The British number one came through his first Grand Slam quarter-final with flying colours, beating Alex de Minaur 6-3 7-5 6-2 to book his place in the last four.

You can read Matthew Henry's report right here.

Draper was superb and has still yet to drop a set - it's shades of Emma Raducanu in 2021 - but there was still the odd tricky moment.

Not least when he needed a medical timeout and had his right thigh strapped up early in the second set.

De Minaur was also struggling but showed real grit to push Draper all the way in the second set. However, Draper stood firm and dominated the third to clinch a huge win.

We have to wait until Friday for his semi-final but we'll be back on Thursday when it's women's semi-final day in New York. Be sure to join us for that!

Karolina Muchova will face either top seed Iga Swiatek or American sixth seed Jessica Peluga in the semi-finals.

They are the first match of the evening session on Arthur Ashe and while Peluga will have the backing of the crowd, Swiatek goes in as the favourite.

Following that one, it's a blockbuster men's quarter-final between world number one Jannik Sinner and 2021 US Open champion Daniil Medvedev.

Jack Draper will be watching. He will face the winner in the semi-finals on Friday.

Karolina Muchova spoke earlier after beating Beatriz Haddad Maia to reach her second consecutive US Open semi-final: "A little bit of a weird match I have to say. I had some problems but I wouldn't like to comment on them if that's fine. I'm happy I managed it with the run to the bathroom and back. Sorry if I disturbed anyone but I had no other choice."

On serving for the match with new balls: "They helped a lot. The ball goes faster, and you can put more spin on, so I was pretty happy. I was trying to put the first serves in. I knew it could make some problems so that was nice."

On the sports she played as a child to help develop her tennis game: "My dad was a footballer and I was always around my brother so it was handball, football, volleyball, everything, synchronised swimming, all the weird things so I'm sure it helped me with the moves."

On facing Iga Swiatek or Jessica Pegula in the semi-finals: "I'm really happy. I wouldn't say that before the tournament. Let the better player win. Every round is very tough here and I'm sure it's going to be a tough and exciting match."

That's almost it from us after a momentous win in the young career of Jack Draper.

His straight-set win over 10th seed Alex de Minaur means he is the first British man through to the US Open semi-finals since Andy Murray in 2012 - the year he won the tournament.

More on that in a moment but first, a look at what else has happened today at Flushing Meadows and what is still to come...

There will be a massive, massive step up in class and level for the next match and that is going to be a huge gulf of difference and he is suddenly going to have to find a much higher level.

He has shown everyone that he can play at a high level it's whether he can sustain it against one of these big guns.

It's either going to be Medvedev or Sinner and that is a huge, huge difference in terms of the calibre of opponents he has been playing.

Jack Draper has taken advantage of the fact that Carlos Alcaraz went out and then he's absolutely thrashed the guy that beat Alcaraz. That's all you can do.

He is handling every stage of this as well as you can. If he carries on like this, who knows where it might take him.

The next match he will genuinely play one of the best players in the world, certainly the two best players left in the draw ranking wise and achievement wise are playing each other tonight and he will play the winner.

It's going to get tougher but my word has he been impressive.

While Jack Draper can look forward to his first Grand Slam semi-final, the wait goes on for Alex de Minaur.

The Australian has made four quarter-finals but is yet to win through to the last four.

He was forced to withdraw ahead of his quarter-final against Novak Djokovic at Wimbledon because of a hip injury and that appeared to be bothering him again today.

Real frustration for him but there will be other chances for the 25-year-old. He'll just hope he's fully fit when the next one comes.

Anon: Jack, you're the real deal... you're going all the way.

Jon: I would say unbelievable, but I’m not sure it is - there are statements, but this was standard! Jack Draper was great throughout; dominated his serve of course, pacey & pushed De Minaur wide and centrally; in open play his power shrank his opponent. Draper should be feared by ALL!

Britain men's number one Jack Draper speaking after beating Alex de Minaur to reach his first Grand Slam semi-final: "To be out here, my first match on the biggest court in the world, it's a dream come true for me. Thank you for the support, it means the world."

On how he beat De Minaur today: "I think I played a solid match. I feel the best fitness wise that I have in a long long time. That's where Alex has got me in the past. I think he was struggling a little bit today with something which may have helped me a little bit. Credit to Alex, he is an amazing fighter, an unbelievable player and we are going to have many more battles to come."

On whether he will watch the match between Jannik Sinner and Daniil Medvedev: "I'm a big sports fan and a big tennis fan so I'll definitely be watching the match tonight if it doesn't' go too late and just enjoy the win and relax."

Jack Draper has got a bit of time to enjoy this moment - and what a moment it is for the 22-year-old! - but it won't be long before attention turns to the semi-final.

He already knows that it will be an enormous test against a Grand Slam winner. But which one?

Jack Draper has a 100% record in Grand Slam quarter-finals...

He was the first Brit into the US Open men's singles quarter-finals for eight years, he's the first into the semis in 12 - and he's yet to drop a set.

Alex de Minaur might not have been at 100% but Draper still had a job to do and he was ruthless.

The left-hander sent down 11 aces, won 84% of his first serve points and hit 40 winners. Brilliant stuff.

Pam D: Wowser! Great work Jack. You made it look easy and it wasn’t easy! Well done lad!

Richard: Never in doubt, tonight. Great performance.

Sam: Has there been another player so in control of their emotions since Federer?

Jack Draper is starting to come of age.

I have got goose bumps after watching that, it was absolutely breath-taking.

I think he will have won quite a few hearts with the way he won that match.

He handled everything about this match with perfection.

Stunning!

Unbelievable defence from Jack Draper to stay in the point before nailing the passing shot beyond a helpless Alex de Minaur.

And another forehand winner. Three match points!

Ace. Three points away.

Jack Draper breaks again!

He is within touching distance now.

Alex de Minaur tries to hit his way out of trouble but can only find the net.

Are the wheels finally coming off for Alex de Minaur?

A wild forehand begins his service game and from there Jack Draper is able to bring up three break points...

It's good point construction from Jack Draper, he is keeping his wits about him.

He's completely relaxed, almost nonchalant.

Big hold and Jack Draper takes another step towards the semi-finals.

Another heavy serve brings up advantage before Alex de Minaur goes long.

What has the Australian got left?
