An absolutely remarkable second-set tie-break has finally come to an end on Court One, with Matteo Berrettini winning it 18-16 to level his first-round match against 41-year-old Stan Wawrinka.

No breaks of serve in the match so far and the tie-breaks have both gone the distance and then some.

Might be a long night on Court One... and the roof is now closing, so the rest of the match will be played indoors.

For somebody who hasn't played singles in four years I think it's extraordinary the level she has already brought. It is jaw-dropping.

Serena Williams brings Centre Court to a crescendo as she nails a backhand lob, the ball touching down a foot before the baseline.

A blink and you'll miss it hold to love.

Jan Choinski has broken Vit Kopriva's serve twice in the early stages of the third set and is surging towards victory.

The Briton got to the second round at Wimbledon in 2023 and that's the only time he's previously won a match in the main draw of a Grand Slam.

I wonder what's going through Maya Joint's head at the moment.

Perhaps that first point tells you exactly how she's feeling - that forehand was miles long and it's met with a huge roar from the crowd.

A loose backhand from Maya Joint gives Serena Williams the first point of the match, much to the delight of the Centre Court crowd.

The pair trade points for 30-all before Joint closes out the hold. A relatively low-octane start.

Maya Joint won the coin toss and will serve first.

Time for another vote - thumbs up if you think Serena Williams will win, thumbs down if you fancy an upset for Maya Joint.

If there is a player that has the most aura in tennis, it is Serena Williams.

I remember playing her for the first time and I felt like I was looking into a TV screen when I was going to serve to her because it felt so surreal. I can imagine Maya Joint is also feeling that way tonight.

The energy in this stadium is electric right now. They have just closed the roof as well so everything will be amplified, it is going to be electric.

I honestly think this is the best draw Serena Williams could've got.

That's nothing against Maya Joint though. She went out and won Eastbourne last year so we know that she can play well on this surface, which is so intimidating to so many.

But the fact is the young Australian hasn't had a great year, she has only won two matches on the WTA Tour level. She will be going out today feeling way overwhelmed by the moment and without a lot of confidence in her own game.

Maya Joint will have grown up watching Serena Williams and Venus Williams compete, but never in her wildest dreams would she have ever thought she would get the opportunity to play against either of them.

It was interesting to hear her interview before the tournament started where she said that actually she really wanted to play Serena Williams. I'm not sure many of the other players would've said that.

She has heaps of talent. She knows her way around the grass court after winning Eastbourne last year. But this year has been a real struggle for her, she hasn't done much winning recently. When you're low on confidence, it isn't an easy prospect to go out and face one of the greats.

Of course, Serena Williams isn't the only player on court nor the only one who will enjoy this occasion.

Australian Maya Joint is making her Centre Court debut as she hopes to score a major upset and clinch her first Wimbledon main-draw win.

The 20-year-old Australian is a former top-30 player but has slipped down to 87th in the rankings after winning just three singles matches (two at Tour level) in 2026.

Everyone was stood up with their cameras at the ready, wanting to capture the exact moment Serena Williams stepped back onto Centre Court.

There's a a roar of noise as the seven-time singles champion strides over to her chair, but it goes up another level when she removes her headphones. The crowd want her to feel the love.

How many matches will Serena Williams win on her singles comeback at Wimbledon?

Wimbledon asked Serena Williams if she was sure she wanted to take the wildcard this year, and she replied something like: 'Honestly, I'm not quite sure' - well, you better be sure now because you're in the main draw!

It is a lot to take on as an athlete to go out there as a seven-time champion and have all of these eyeballs critiquing everything you do. She has nothing to prove, but it is a lot to put yourself out there like this. I wouldn't want to do it, that sounds like torture!

Here they are! Side by side, Serena Williams and Maya Joint enter Centre Court.

The atmosphere in here is going to be electric. They've just closed the roof on Centre Court, so all the noise that that greets Serena Williams on her return to Wimbledon is going to bounce straight back.

We were told Serena Williams and Maya Joint would make their entrance onto Centre Court at 19:26 BST.

We're one minute away...

Williams, headphones on, is the picture of calm as she navigates the familiar corridors behind Joint.

Meanwhile, on court 16, Great Britain's Jan Choinski is into a two-set lead against Czech player Vit Kopriva.

After breaking to take a 6-5 lead, Choinski was 0-40 down but recovered to hold serve and move within one set of the second round.

The Williams sisters - who will team up again for the doubles here - are synonymous with Wimbledon.

For a 19-year period, at least one Williams sister was in all but four singles finals at SW19. They won a combined 12 Wimbledon singles titles - seven for Serena and five for Venus - between 2000 and 2016. Elder sister Venus won it first. Little sister Serena won it more.

When they combined they were dominant, winning six women's doubles titles together. When they faced one another it was absorbing - two players who knew each other's games inside out, from years spent on the practice courts in Compton, California.

If you think of the Williams sisters you see them in the Wimbledon whites, moving around a grass court, two beautiful service motions, with athleticism, power, and touch at the net to boot.

As Serena said - it is not every day Wimbledon holds a wildcard for someone.

"I can name probably like a handful of people. I happened to be one of them," she said.

"I thought, 'I should really take this opportunity'. Who knows if I'll ever make it here again? This could be it.

"I was like, 'What's wrong with you, Serena? What are you thinking? Are you nuts?' I have this great opportunity to showcase what I do best."

Will her age and all that comes with it - being half a step slower out of the corners of the court, having to conserve more energy the longer a match goes on - be too tough to overcome?

Or will her aura, the sheer sense of simply just being Serena Williams, be enough to carry her through the opening round at least?

David Quayle, Williams' British hitting partner who helped her prepare for her return in the doubles at Queen's earlier in June, says it is "hard sometimes not to feel a little bit nervous" around Williams.

"It's a funny thing to see someone that you have watched their serve on TV for so many years, and then all of a sudden that serve is coming at you," he told BBC Sport in June.

"You're fighting between admiring some of the shots and actually playing them. She's got that kind of aura.

"I'm starting to getting a little bit more used to seeing her over the other side of the net, but every day is special."
