Carlos Alcaraz holds to love again.

The weather being extremely hot makes the conditions faster, the balls are travelling faster through the court.
You have to feel for Fritz because he tried so hard in the second set, got himself going and he just dropped for three or four minutes? Out of that, he's a break down and you have a feeling this set is going to be difficult to turn around.
The body language from Alcaraz is better, he is full of energy again and bringing the flair.

You are living on the edge.
What people don't know is that living on the edge in tennis exponentially will eventually work against you.
It's what your average can do, not what your highlights can do.
Fritz 4-6 7-5 2-3 Alcaraz*
Taylor Fritz gets the hold. My word, he needed that.
The big-serving American does exactly that, with a couple of 130mph+ serves, giving Carlos Alcaraz little chance on the return.
The Spaniard remains a break up.
*Fritz 4-6 7-5 1-3 Alcaraz
13 points in a row for Carlos Alcaraz.
The Spaniard very quickly puts the pressure back on Taylor Fritz.

What a way to seal the break by Carlos Alcaraz, drawing his opponent into the net then lobbing him. He's been under big pressure in the last few games but has ridden through it to get his nose in front once more.
It felt like the momentum was with Taylor Fritz but Alcaraz has stopped that in its tracks.

Isn't this incredible? After such a terrific second set and playing at such a high level, Fritz is really fuming to so quickly be handing the initiative back to Alcaraz early in the third set.
That's the thing about great champions - they can keep bringing that level and keep asking the questions.
Fritz 4-6 7-5 1-2 Alcaraz*
Deary me, Carlos Alcaraz. That is special.
The Spaniard gets his second break of the match and this one comes with Taylor Fritz playing his best tennis of the match.
The defending champion wins all four points without response, ending the game with a deft drop shot that Fritz retrieves, only for Alcaraz to send him running on the lob.

Incredible.
This is quality serving from Taylor, but Alcaraz has just responded here to the challenge of having lost the set.
*Fritz 4-6 7-5 1-1 Alcaraz
Well, that's some response from Carlos Alcaraz.
His focus and intensity levels definitely dropped during that second set.
But encouraging signs there that he's back on it, with the Spaniard holding to love.
Fritz 4-6 7-5 1-0 Alcaraz*
Taylor Fritz takes the early lead in the third set by holding to love on his service game.
The American started off there like he finished off in the second.
The fifth seed finishes off the hold with an brilliant ace down the line.

Surprised 'oohs' from the crowd after Carlos Alcaraz double-faulted and that was followed by a big cheer as Taylor Fritz sealed the break to take the second set, as they know we have a match on here now.
Alcaraz was on another level in the first set but Fritz stepped it up in the second, upped the scoreboard pressure and now it is all square.
If Alcaraz is going to have a chance of winning a third Wimbledon title in a row, he's now going to have to really work for the opportunity.
*Fritz 4-6 7-5 0-0 Alcaraz
Carlos Alcaraz stands alone at the back of the court, with Taylor Fritz taking a short break.
May be the only shaded area on Centre Court actually, so it's quite a smart play.
Fritz is back now and we'll soon be getting the third set under way.

Each day the 27-year-old Briton is asked by the world's leading players to mimic the style of their next opponent on the All England Club practice courts.
This morning, he was Taylor Fritz.
As a Wimbledon hitting partner, Jones has been the go-to guy for Carlos Alcaraz this year and warmed the Spaniard up for this semi-final.

I didn't see that coming at all. I always felt Carlos was in control but serving first made a real difference for Fritz in that set.
As you get towards the back end of the set, the pressure is enormous on the player serving.
Hats off to Fritz, he really earned that set. I think we're in for a real tussle now.
*Fritz 4-6 7-5 0-0 Alcaraz
Tim Henman
Former British number one on BBC One
That was what we talked about. Building scoreboard pressure, getting your nose in front and dealing with your own tennis.
The intensity dropped from Alcaraz. All of a sudden it is game on and one set all.
*Fritz 4-6 7-5 0-0 Alcaraz
Marion Bartoli
Former Wimbledon champion on BBC Radio 5 Live
Carlos Alcaraz has been feeling this pressure for 30 or 40 minutes now and it's shown for the first time.
*Fritz 4-6 7-5 0-0 Alcaraz
All square!
Taylor Fritz has been a little bit better on his return games but I certainly did not see him breaking to love to win the set!
Two unforced errors and a double fault in that game from Carlos Alcaraz, whose level has dropped for a couple of games at just the wrong time.
