Fritz 4-6 7-5 3-6 4-5 Alcaraz*
Has there ever been a better player on volleys than Carlos Alcaraz?
He goes to 30-0 by completely shifting his body weight and softly volleying a deft shot back over the net, which Taylor Fritz can't get to on sprint.
The Spaniard secures the hold to love - again.
Fritz will come out to serve next to stay in this match.
Fritz 4-6 7-5 3-6 4-4 Alcaraz*
Some huge serving from Taylor Fritz there, just when he needed it most.
The American holds to 15, without giving Carlos Alcaraz much of a look of a break opportunity.
De la Puente 0-3 Hewett*
It is hot off the court and it is hot on the court for Alfie Hewett.
The defending champion is off to a flier in this semi-final with Spain's Martin de la Puente as he holds his serve comfortably before putting more pressure on the third seed.
Hewett can't take the first two break-point opportunities, but a superb forehand return brings up another and a volley at the net secures the double-break.

Straightforward hold for Carlos Alcaraz.
He puts Taylor Fritz back on serve. Can he put the American under the pressure needed to earn a break?
Let's see.

Excellent stuff from Taylor Fritz.
The American saves a break point, which he gifted to Carlos Alcaraz after firing a simple forehand long.
But the fifth seed takes the next two points on deuce for the hold.

That's a beautiful expression of how much feel he has on his racquet. There was never a doubt that he was going to make that ball.
*Fritz 4-6 7-5 3-6 2-3 Alcaraz
That's a frustrating one for Taylor Fritz.
The American gets to 15-30 and sniffs the opportunity to break.
But Carlos Alcaraz produces two body serves to win consecutive points and he earns the point with his trademark fake drop shot winner.
De la Puente 0-1 Hewett*
Defending champion Alfie Hewett is under way in his men's wheelchair singles semi-final with Spain's Martin de la Puente.
It is the ideal start for the Briton as he manages to break the third seed in the opening game.
Fritz 4-6 7-5 3-6 2-2 Alcaraz*
Seriously impressive from Taylor Fritz.
The American fires off *four* aces in a row in devastating fashion to secure the hold in the blink of an eye.
Much better from the fifth seed.

When you get to this stage of a match, serving first is clearly an advantage. You always feel like you're a sprint away from the finish.
*Fritz 4-6 7-5 3-6 1-2 Alcaraz
Not a lot of tennis to report on in that game or indeed the set so far.
These two are proving very dominant on serve and giving little up in terms of break opportunities.
Fritz 4-6 7-5 3-6 1-1 Alcaraz*
That will give Taylor Fritz a bit of confidence.
The American holds in a flash, putting Carlos Alcaraz back on serve almost immediately.
*Fritz 4-6 7-5 3-6 0-1 Alcaraz
Missed opportunity for Taylor Fritz.
The American goes 0-30 up - and you can sense he's hoping that Carlos Alcaraz's focus had dropped from winning the third set.
But no such luck.
The Spaniard takes the next four points to take the hold.

I hope he plays with this joy always, Alcaraz.
It just transmits to everyone watching. He is just having a great time, obviously.

Taylor Fritz's body language has shifted significantly, and who can blame him? He barely had time to celebrate his battling second-set display before Carlos Alcaraz stepped it up another gear.
Just a high-quality response by Alcaraz to a high-pressure moment.

Fritz can still turn this fourth set in his favour.
But, when Alcaraz got off to the fast start and an early break, he has just looked so comfortable and confident with his game.
Disappointment for Great Britain's Mimi Xu, who has lost in three sets in her girls' singles semi-final against American Julieta Pareja.
Sixth seed Pareja won the decider 6-4 to progress to the final.
British interest continues in the men's wheelchair singles, though, with Alfie Hewett set to get his semi-final under way on Court One against Spanish third seed Martin de la Puente.

Carlos Alcaraz secures the third set by breaking Taylor Fritz for a third time in the match.
The Spaniard earns two set points and lets the first one pass him by.
But after a solid return on Fritz's serve, the American hits a forehand long to gift Alcaraz the game.
