Arthur Fery is clinging on in this match.

The Briton goes wide with his serve and Zizou Bergs can't get it back.

This is where Arthur Fery really enjoys the new ball because it goes through the court a little bit quicker and it puts a little bit of pop on his serve.

He senses there's a little bit of tension in the Belgian right now. He's got the break so let's see what happens.

Arthur Fery keeps plugging away and gets to deuce.

Nothing is coming easy for Arthur Fery at the moment. The Briton battles to 15-15 and then 30-30.

Hmmmm.

Zizou Bergs has break point.

Madison Keys is a break down but the 26th seed is a break up early in the second.

A double fault from Amanda Anisimova gifts the game to her fellow American and Keys then comes from 0-30 down on serve to consolidate the break.

Zizou Bergs defends the first.

But a double fault hands over the break.

Still work to do here for Arthur Fery - he trails by a break - but it's movement in the right direction.

It's a real shame that things have got away from Arthur Fery in the third and fourth sets here. For me, it's just experience and he will learn from this match. Some of my best learnings were from the biggest losses that I had, and that's exactly what he will experience here.

It has been great to see what he has been doing at Wimbledon, but things definitely got away from him today. We've seen him getting frustrated and seeming a bit tired.

Here we go.

The Brit could never really get a hold of this match.

There was a period at the end of the second, start of the third where you thought maybe, but since that he has just been brushed aside.

Arthur Fery let out a huge scream in anger after putting into the net to hand over that break.

Can he get his emotions in check as he looks to hit back?

Madison Keys actually won the toss in this match - and that's the first decision a tennis player has to make when they walk out onto court. She chose to receive and I think that really cost her in that first set.

The first set has gone the way of last year's finalist Amanda Anisimova in the all-American contest on Centre Court.

The sixth seed got the crucial break at 4-3 and served it out to 30. Anisimova had 16 unforced errors to Madison Keys' eight in that set but also had more than twice as many winners.

Zizou Bergs is threatening to wrap this match up in quick fashion now.

Alexander Zverev continues to offer very little on serve as Marcos Giron goes into the net.

The German second seed then brings up four set points as Giron overcooks a forehand, and takes them at the third opportunity with a deft volley at the net.

It's a long way back for Giron from here.

It's another hold for Zizou Bergs as Arthur Fery powers a forehand a long way over the baseline.

The Belgian is looking very strong on serve again and will now look to put pressure on Fery as he hunts for the double break.

Arthur Fery gets the crowd on their feet with a brilliant passing shot to make it 15-15 on the Zizou Bergs serve.

Plenty more shots like that are going to be required if the Brit is to fight back in this one.

It is tough for Fery to get into the rallies. He is straight away on the backfoot. He has to hang in there.

If there is a dip from Bergs, he has to be ready to take it and any opportunities that come his way.

Arthur Fery's second serve was punished again in that opening service game, he wasn't hitting his spots. The backhand side is also breaking down a little bit, he isn't willing to go deep enough in the rallies.

Zizou Bergs has been having easy service games because his first serve is so much bigger than Fery's and his serving percentage is so much better.

With a bit of help from the net and some more big first serves, Alexander Zverev goes into the change of ends with a 4-2 lead.
