It's all going off.

The crowd leap up as Nick Kyrgios finally seizes a break point at the sixth opportunity to clinch the second set and level things up.

Stefanos Tsitsipas then receives a warning for smacking the ball into the crowd. Kyrgios wants his opponent defaulted and the Greek is booed as he returns to the court.

But on we go.

Nadal is furious with himself as he punches a volley long on his serve, even though he's a set and two breaks ahead. It doesn't matter though, he gets the job done and he's 4-0 in front.

Amid the carnage and drama on Court One, it's as routine as possible on Centre Court.

Meanwhile, Kyrgios is complaining that Tsitsipas hit a ball into the crowd and wants him to be defaulted.

"You're a disgrace," he tells the umpire.

Tsitsipas gets a warning while a supervisor comes out to chat with Kyrgios. Tsitsipas takes the opportunity to go to the loo.

"I'm not playing until we get to the bottom of this," Kyrgios says.

Quite frankly I'm surprised it took that long for Kyrgios to get that warning.

Whatever his thoughts on that, he claws himself back to 30-30 before Tsitsipas slams down an ace. He can't convert game point and we go to deuce, but soon enough, Kyrgios has break and set point.

He gets it with the most casual shot you'll ever see.

Second set to Kyrgios.

A little trip by the ball boy right in front of Nadal is a reminder that this surface can be a little slippery. The pair nod at each other, a sort of 'are you ok' , 'yes i'm fine, thanks' in international language.

Nadal looking for a double break, 30-40 on the Sonego serve. And Nadal gets it. Sonego aims to find the angle but can't get his maths right and puts it wide.

Nadal in cruise control and you need a good imagination to see Sonego turning this set around from here.

In my opinion if you're called out for that you should forfeit a point or a game. We're at Wimbledon here.

The problem is you forget there are two people on the court here.

Kyrgios has just been given an obscenity warning.

Boos from the crowd.

I think Stefanos Tsitsipas is well within his right to say that he wants a bit more time. The ball kids are still moving and Nick Kyrgios is going to serve.

Kyrgios was becoming increasingly vocal but he seemed to calm down as he reached his fifth break point of the match in the previous game.

Some wonderful serving shuts the door on Tsitsipas' first opportunity and there are spectators on their feet to applaud the Australian as he wriggles free to hold.

Are we destined for another tie-break in this Saturday night showstopper?

People are on their feet in front of me to applaud that game wn for Nick Kyrgios to hold his serve. Despite his outbursts, despite his antics, people love him.

A Kyrgios drop shot tickles the top of the net as it drops over for 40-0. Kyrgios is storming through this game but he's stopped in his tracks with two lazy shots pushed into the net.

Then a wayward forehand flies wide and suddenly we're at deuce. If Tsitsipas breaks here then Kyrgios has only himself to blame.

Tsitsipas then has his first break point of the match, but Kyrgios responds with an ace, then moving to hold.

We saw two very different Kyrgios' in the space of about 30 seconds there. That was a bit bonkers.

Sonego does at least manage to win a couple of points off the Nadal serve, but only two as Nadal holds to consolidate that early break.

There's a huge roar from the Court One crowd sense an opportunity for Nick Kyrgios when he goes 30-15 up on Tsitsipas' serve, the Greek flailing at a Kyrgios lob and failing to land it between the lines.

That opportunity dissipates as Tsitsipas takes the next point with an ace, but break point soon arrives for Kyrgios. He's had four so far, zero converted. What about this one?

Nope.

After two more deuces and three Tsitsipas advantages, the fourth seed holds.

Nadal was not at his best in the previous rounds, dropping a set in both. But he has definitely stepped up several levels today.

Maybe he saw Novak Djokovic's similarly one-sided match on Friday and he's just making a little bit of a point...

He just seems so full of energy, bouncing between points. Nevermind the nerve-blasting treatment he's had in his foot, it's like he's had springs inserted in there.

Two break points for Nadal. He goes long with a forehand from the baseline on the first of them, but a stunning crosscourt passing winner gives the second seed the break.

Sonego being outclassed and, following 36 minutes of dominance, Nadal is a set and a break up.

Sonego tries something from the party book with a 'tweener, but Nadal is at the net to smash away a winner, before then moving to 15-30 and the Italian is already on the ropes within seconds of the second set starting.

Alice Stainer: It seems to me that #Rafa, external has a different energy about him today. More focused, more confident & authoritative. He's found his #Wimbledon, external!
