I wonder if it's a nervy experience playing in front of all these sporting superstars?

It's a real A-list line-up on Centre Court.

Shouts of “USA, USA, USA” come from who I imagine are Ben Shelton’s friends sat close to me.

The American is a break up in the third set.

That's good from Norrie.

Another no-nonsense hold from the Brit keeps us on serve in this second set.

It is frustrating for Norrie because he has got to take advantage of those opportunities when he gets a second serve (from Zverev).

Norrie shouts up towards his coaching box. He's frustrated with himself for not taking advantage of Zverev's second serve. He's not going to get many of those opportunities so he has to capitalise when he does.

Zverev takes the hold with a huge ace.

Suddenly, we have bright skies again and the rain has stopped.

Covers come off on courts 14, 15, 16, 17 and 18 and the crowds cheer as they start to put their umbrellas away.

Norrie was looking in a spot of bother there but takes the hold to 30.

We're just hearing that Emma Raducanu has pulled out of the mixed doubles because of stiffness in her wrist.

She was due to play alongside Andy Murray later today.

That means the former British number one has played his last match at the All England Club after he and brother Jamie Murray were knocked out of the men's doubles earlier this week.

A positive weather update - yes, really - and the covers are off on court two.

With 10 minutes before the earliest possible restart on the outside courts, the rain has stopped and fans are starting to filter back into the stands.

Should it stay dry, Harriet Dart will resume at deuce on her serve against Wang Xinyu of China. The Brit is currently a break up in the first set.

Three lions on a shirt...

Emma Raducanu shows her support for England's men's football team during practice earlier today.

While Raducanu has got the football fever, there isn't much of a Euro 2024 vibe around the All England Club.

Today's game will not be shown on any screens around the grounds.

This is all Zverev needed to take the first set.

Can Norrie respond?

Norrie saves the first set point but then drops his head when he can only nudge Zverev's serve into the net.

A pretty straightforward set for Zverev. Norrie served well but has been unable to make a dent in the German's own huge serve.

Little cries of 'come on!' from Norrie as Zverev challenges a call. The ball was called out and Zverev thought his shot was good but nope, it was indeed out.

Zverev quickly bounces back though. A brilliant little volley brings up two set points.

A couple of mediocre drop shots from Zverev allowed Norrie to hang around in this first set.

Looks like the photographers spotted Roger Federer at the same time as Charlotte!

He's brought along his parents, Robert and Lynette, to watch on Court One today.

Update on Roger Federer spotting… I couldn’t see him because he’s sat about seven seats to my right. Incredible.

Lovely stuff. Norrie holds serve to force Zverev to serve it out.

He draws Zverev into the net then fires a passing forehand down the line.

Nice. Norrie's serve once again gets him out of trouble and he moves to advantage with a pinpoint ace.

A couple of good serves get Norrie back on track but Zverev is dictating from the baseline once again.

Set point.

I’m also told somewhere on Court One is tennis legend Roger Federer.

Now, despite wearing glasses, my eyesight isn’t great but I’ll try my best to spot him.
