That will do it! An ace down the middle moves Jannik Sinner one set away from becoming the Wimbledon champion again.

Sinner, from slipping in the rally, takes the first break and the racquet throw is what Zverev thought about that.

Talk about the turning point... for Zverev to have that break point on Sinner's serve to then flexing his knee, it really has changed the complexion of this set.

Alexander Zverev finds the fence and Jannik Sinner, all of a sudden, has three set points.

Blimey, you wait for over two hours for a break point and then two come in quick succession.

London buses and all that.

Sinner's first chance came in the eighth game of the first set at 4:45pm - now he's finally made the breakthrough in the eighth game of the third set.

Jannik Sinner slips, but he's back up in a flash to resume the rally and Alexander Zverev goes long.

The first break of the match and it goes to Sinner.

He'll serve for the third set now.

Oh dear. A double fault by Alexander Zverev and suddenly we're back at deuce.

And the German then misses the baseline by a hairsbreadth.

It's a break point for Sinner.

That fall doesn't seem to have impacted Alexander Zverev as he opens up his service game with an ace.

But after bringing up game point he allows Jannik Sinner back in and we go to deuce.

There is nothing in it. Absolutely nothing in this match.

That fall for Zverev was unsettling for him but it is a good sign he hasn’t asked for the trainer.

Oh no. That was a real heart-in-mouth moment when Zverev went over.

Anyone who was there at the 2022 French Open semi-final where Zverev fell over and ruptured ankle ligaments had a horrible sinking feeling.

Thankfully it is nowhere near as serious this time.

Jannik Sinner stays composed, saves the break point and wraps up the hold to stay in front.

Zverev looks to be OK. Must have been the shock of the fall, more than anything.

Jannik Sinner runs over and helps Alexander Zverev back to his feet. A good sport.

The German seems to be OK, but that break point - his first of the match - has disappeared.

Oh no. Alexander Zverev is down.

He's clutching his right knee.

Alexander Zverev holds his hands on his hips and glares up at his team. He knew how big of a chance that was, but Jannik Sinner aces to move 40-30 up.

An inside-out forehand winner down the line from the German gets us to deuce though.

And now he's got break point as Sinner nets!

Alexander Zverev holds his head in his hands after planting into the net. 30-30.

Now the door opens for Alexander Zverev after Jannik Sinner double faults and then sends a forehand wide. 0-30.

You just feel the energy level of Zverev is starting to come back slightly.

He is on his toes right now, bouncing around.

Groans from the crowd as Alexander Zverev, after taking an age to step up to the baseline, is interrupted by a shout from the crowd. His ball toss goes wayward, he has to do the whole routine over again and ultimately fires long.

An ace gets him back on track, though, and he holds. That was good bit easier than his last couple of service games.

It feels like it is starting to lean a little more towards Sinner now. I think he has stopped allowing Zverev to dictate. When he gets into the point, he starts controlling it. That’s an accumulative effort. But they are still small margins.
