Arthur Fery will have the unknown factor against Alexander Zverev.

He needs to use that to his advantage because they have obviously never played. I'm sure Zverev will have seen him play a bit this week, but it is different to actually being on the court and facing him.

He won't know how the ball comes off the racquet or the different problems that he possesses.

We will shortly turn our attentions to the semi-finals of the women's singles, which will get under way from 13:30 BST with Karolina Muchova v Coco Gauff.

But first, let's get some more reaction to Arthur Fery's extraordinary run to the men's semi-finals.

Alfie Hewett, speaking after his straight-set win in the men's wheelchair singles quarter-finals: "He has a lot of weapons in all sides, strong forehand, backhand and serve comes through quick. Very good on the grass, if you get a bit of momentum, confidence, it can be difficult to break that.

"I rode my luck a little at 5-4, but in second I just served a bit better and tried to keep the ball out of the spot a bit more."

On form coming in: "Every week is different. The slam weeks are always special and anything can happen. As much as I take confidence and performance from those results, it is is never a given so just happy to get through today's match."

On expanded grass court season and how much of a difference it makes: "It is incredible. We have been saying it for years that the more grass court tennis we can have the better for everyone involved.

"It is a real special time or us Brits. I don't want it to end so hopefully it can continue."

Britain's Andrew Penney has been knocked out of the men's wheelchair singles, losing his quarter-final 6-0 6-1 to third seed Martin de la Puente.

The Spaniard will next face defending champion and top seed Tokito Oda, who has just closed out a 6-2 6-2 victory against fellow Japanese player Takuya Miki.

Oda had previously defeated Britain's Gordon Reid in the last 16.

Alfie Hewett meanwhile will play Gustavo Fernandez of Argentina, the fourth seed at this year's Wimbledon.

Fernandez beat American Casey Ratzlaff 6-0 6-1 in his quarter-final.

In the second set, Alfie just streaked ahead.

When he is playing well and within himself, not forcing it, he is great. When he is forcing, something he needs to look at, just be a bit calmer, get your first serve in and look where your opponents strengths are.

Ji Zhenxu shows he still has come resistance left in him by holding serve for the first time in the second set, forcing Alfie Hewett to serve for the match.

Hewett, who is much calmer now after looking very frustrated during the first set, needs no second chance - he holds to 30 and wins the match with a beautiful backhand into the open court.

In the end, it was fairly straightforward for the British number one.

Another bullet forehand by Alfie Hewett. I think he is sensing the finishing line here.

You can see the confidence has returned for Alfie Hewett after that first set wobble. A terrific backhand winner flashes past Ji before he can move to the delight of the home crowd - the Brit has hit double the number of winners compared to his opponent today.

Hewett seals the double break, and holds his own to move one game from the last four.

This is identical to the scenario in the first set, but what a tussle that turned out to be.

Hewitt will want to avoid Ji's fightback here in the second set.

Alfie Hewett wants normal service to resume on number three court, and a splendid winner down the line earns him a break point on Ji's serve.

But Hewett's radar still isn't quite perfect, as he sprays a backhand return way wide to take us to deuce.

Hewett earns another break point - and yet another double fault from Ji hands the break to the second seed.

Hewett consolidates the break, and will aim to wrap up this quarter-final in double quick time.

All aboard the Fery at 13:30 BST on Friday!

The Centre Court order of play has just been released for tomorrow and Britain's Arthur Fery will take on French Open champion Alexander Zverev in the first semi-final.

World number one and defending champion Jannik Sinner will then face 24-time major champion Novak Djokovic after the conclusion of that match.

The highest temperature ever recorded at a Championships is 35.7C back in 2015. Today's temperature could get close to that. Humidity is also higher today than it was earlier in the Championships. We're likely to see the peak of the heatwave today at Wimbledon. Temperatures are expected to drop a little by tomorrow, but will remain above 30 degrees for the next two days.

Ji is clearly full of belief now, racing into a 40-0 lead on serve. But some great defensive tennis from Hewett holds off the charge, and he roars in delight as a winner down the line takes it to deuce.

And when Ji plonks a backhand into the net it hands set point to Hewett... which he takes thanks to Ji's fifth double fault of the match!

A hard-fought first set won by Hewett, he will look to wrap up this match sharpish in the second.

In the early stages of this match, it looked as if Ji would not have the quality or courtcraft to properly trouble Hewett.

But despite Ji's latest service game being taken to deuce by Hewett with some help from the net cord, the Chinese player manages to hold for the first time in the match - forcing the Brit to try and serve out the first set.

Hewett's frustration is clear as an attempted back hand pings off the frame high and wide, leaving him in a 0-30 hole.

And after a loose second serve is walloped back past him, Hewett is broken again - we are back on serve.

Ji is ranked nine in the world, so is no slouch.

Immediately after being broken, Hewett makes it three breaks from three of the Ji serve. Ji pulled it back from 0-40 to 30-40, but cannot fend off the Brit as he springs a forehand wide.

But Hewett is himself broken for his second successive service game, giving it up with a rather lame double fault.

A tricky match for the servers, so far.

Some beautiful tennis this morning from Alfie Hewett, including a terrific backhand down the line on his way to securing the double break.

But unseeded Ji is sticking in this match, moves to 0-40 on the Hewett serve - and secures the break back with a lovely deceptive backhand.

This might be a decent workout for Hewett after all.

The latest episode of Wimbledon Daily is available to listen to on BBC Sounds.

Gigi Salmon, Russell Fuller, Naomi Cavaday, Naomi Broady, Annabel Croft and former Wimbledon champions Pat Cash and Marion Bartoli react to Arthur Fery reaching the Wimbledon semi-finals.

The British wildcard continued his extraordinary journey with a straight sets win over French Open finalist Flavio Cobolli – now the French Open champion Alexander Zverev stands in the way of him reaching the final.

As well as hearing from both Fery and Zverev, the team look ahead to Thursday’s women’s semi-finals – with Coco Gauff facing Karolina Muchova and Marta Kostyuk taking on Linda Noskova.

Alfie Hewett is heavy favourite for this match - he and Ji Zhenxu have three times, including at Wimbledon last year. The Brit has won all three in straight sets.

It was a slightly inauspicious start for second seed Hewett, as he double faulted his opening service game. Still got to shake off those cobwebs - and he does, rattling off four successive points to hold serve.

And Hewett has now fully shown why he is favourite, a beautiful slice setting up two break points - which Ji concedes with a double fault of his own.

Hewett then holds again, and is in complete early control at the first change of ends.
