Another break point. Can she take advantage of this one?

Anastasia Pavlyuchenkova hits it long. She can't believe it.

Deuce.

Norrie dumping that forehand into the net on his fourth break point already feels like it could be very costly.

Big chance gone for the Brit.

Norrie needs to get into this match. These early moments are dangerous.

A settler game for Alcaraz. Four break points saved. He looks so calm, like he is out for a stroll.

Amanda Animisova goes down on one knee as she overcooks a forehand and just misses the line: 15-15.

Anastasia Pavlyuchenkova pegs it back to 30-all with a big smash and gestures to the crowd to turn up the volume.

Advancing to the net, she buries a forehand into the corner for a break point. Pavlyuchenkova is fired up!

Missed opportunity for Cam Norrie.

He works his way into a strong position in the rally, advances but then whips his forehand into the net.

Carlos Alcaraz gets the drop shot out to move to game point and secures the hold when Norrie goes long.

Plenty of empty seats on Centre Court still as many punters stretch their legs and fill their bellies after the first match of the day.

Those who are not willing to miss a second of Alcaraz-Norrie are instantly treated to examples of the Spaniard's explosive forehand.

Wind it up and watch it go.

'Oooohs' follow the ball up the line like it is a firework being launched into the sky.

As quickly as they arrived, Cam Norrie's break points disappear.

Nerveless stuff from Carlos Alcaraz. Point by point, ticking them off... but what's this?

The defending champion puts the ball into the net at deuce and Norrie has a fourth break point.

Amanda Anisimova neutralises Anastasia Pavlyuchenkova's first advantage with a powerfully struck backhand which the Russian does well to even get a racquet on.

At the second attempt, Pavlyuchenkova gets the service game over the line to force Amanda Anisimova to serve for the match.

Early opening for Cam Norrie!

A double fault puts him up 0-30 and then he nails a backhand down the line to bring up three break points...

Anastasia Pavlyuchenkova and Amanda Anisimova exchange points to 30-30.

Thirteenth seed Anisimova fires a forehand long but makes no mistake on the next point - playing it cross-court and kissing the line - to bring up deuce.

Some slow starts from Alcaraz so Norrie needs to take advantage of that if possible.

Norrie has got to be able to hit his backhand flat up the line and make Alcaraz move. Easier said than done.

That's a nice settler for Cameron Norrie on Centre Court.

Down 15-30, he comes through to hold as Carlos Alcaraz fires a forehand beyond the baseline.

Amanda Anisimova's first serve makes a timely return, with an ace to take her to 40-0.

Naturally, as soon as I type that, she misses her next first serve but a booming second serve, which clips the line, seals the game to love.

Anastasia Pavlyuchenkova is serving to stay in the match.

Ready? Play. Cameron Norrie has the honour.

The British number three is the lowest-ranked player left in the men's draw.

He has beaten Alcaraz twice in their past three meetings, although they have not met for two years and never faced each other on grass.

Away we go, Cameron Norrie to serve first.

Anastasia Pavlyuchenkova saves the first break point but goes behind on deuce.

Nothing at all is going the Russian's way as the ball hits the net chord and drops back onto her side. Amanda Anisimova has her breakthrough.

For any Cam Norrie fans searching for reasons to be optimistic, the good news is that he has beaten Carlos Alcaraz before - twice.

In fact, he's won two of their last three meetings. Albeit the most recent was in February 2023 and on clay.

His other win was on a hard court in August 2022 so why not complete the surface set today?

Amanda Anisimova frowns at the ground as a backhand sails long and a cross-court sliced forehand from the baseline drifts into the tramlines to throw away two promising opportunities to put the pressure on Anastasia Pavlyuchenkova.

However, she issues a huge roar as a booming stroke brings up another break point.

You might have thought you wouldn't see Cameron Norrie playing at this level again.

Norrie has endured a difficult time over the past couple of seasons, with a forearm injury last year contributing to his ranking plummeting towards the bottom of the top 100.

But, after a clear-the-air talk with his team after the Miami Open in March, he has rediscovered his form.

Norrie and his team, led by coach and former Texas Christian University team-mate Facu Lugones, talked about how they all needed to rediscover the enjoyment of being on the professional tour.

That means embracing life more when they're travelling the world, with a more relaxed mind leading to better tennis.

Since then, Norrie has reached the French Open fourth round last month before forging another deep Grand Slam run at Wimbledon.
