Andrey Rublev will be asking himself where some of these shots were earlier on in this match. You can see him kicking himself.
That was a good bit of play. He hasn’t been following the ball in quite enough, in my opinion, but he knows his game better than I do!

The crowd rallied behind Andrey Rublev as he stepped up to serve at 0-40 down, sensing the Russian is just beginning to fade away here.
It appeared to do the trick as Rublev showed great fight to come through the first three break points, but its Carlos Alcaraz who receives the appreciation of the crowd as he heads to his chair.
One break in each of the past two sets is all the 22-year-old has needed to turn this around. You certainly wouldn’t back against him seeing this out from here.
Carlos Alcaraz extends his lead with ease, holding to love for the second time this set.
He’s only lost two points on his serve in three games this set.
As you were on Court One, a couple of holds of serve since our last update so Linda Noskova still leads by a break in set two after dropping the first.

There has been one lull per set for Andrey Rublev.
The mistakes are coming like buses aren’t they? You wait for one and then boom, boom boom. Error, error, error all in the same game.
He’s done it!
After letting three break points pass him by, Carlos Alcaraz breaks with the fourth time of asking.
Andrey Rublev’s serve just deserted him in that game.

Huge opportunity for the Spaniard.
Anastasia Pavlyuchenkova awaits the winner of this match – the Russian beat Great Britain’s Sonay Kartal in her fourth-round match earlier today.
Finding a victor won’t be quite as straightforward as we thought at the end of the first set, as Linda Noskova finds a break of serve early in set two.

Carlos Alcaraz is being very clever serve-volleying every point here.
He just doesn’t want Andrey Rublev to settle and get his sights in.

Maybe he’s human after all?
Nevertheless, the Spaniard manages to hold to 30.

It was like lightning.
Almost like the decision, whether deliberate or it just unfolded, certainly in the last round Alcaraz played a high level of tennis throughout. But today, it is like he is just picking moments when lightning will strike and he will just whip that ball.
Another hold to love for Andrey Rublev.
We’ve had three games in this fourth set and only 12 points have been played.
Both players are on top of their serve.

Andrey Rublev is a great competitor. He hates to lose so he will be fighting to the end here, that’s for sure.
He isn’t being pushed back by Carlos Alcaraz either. If you look at where he hits on the rallies, it is about where he stands to serve. He won’t let Alcaraz push him deep behind the baseline.

It is a scary thought that Carlos Alcaraz is still looking to improve.
He adjusted his backhand a little bit recently, making his takeback a little bit lower. We tend to see that move in players who start their careers with bigger swings, because you just don’t have time to take a big swing against the top players.
Deary me, Carlos Alcaraz.
The Spaniard holds to love, doing so with consecutive aces.
Two quick-fire games at the start of this fourth set.

The difference is quite extraordinary.
When Carlos realised he had to elevate his level, he had to produce more, the concentration on his face changed entirely.
