No sign of the Carota Boys, Jannik Sinner's devoted fan group who support him at matches dressed in carrot costumes - something which stuck after he once ate one during a change of ends in a match.

He is instead being backed by a group wearing luminous green T-shirts which together spell out 'JANNIK'.

They're been kept pretty quiet so far, however, after this very promising start by qualifier Shintaro Mochizuki.

Shintaro Mochizuki steps into the court with a backhand which has Jannik Sinner scrambling and he can only find the net.

Shortly after Sinner is unable to control a half volley at the net and Mochizuki has an early break point.

Drama on Court One!

Felix Auger-Aliassime is serving for the match but Alejandro Davidovich Fokina is not going down without a fight.

Some sparkling groundstrokes and an unbelievable refusal to give up on a point help the Spaniard earn two break points.

But then he goes down injured... Thankfully, after a bit of treatment he is going to be able to continue.

That was a nice settler for Shintaro Mochizuki, he needed that. I do think he needs a good start here.

I had the absolute pleasure of commentating on his previous round win over Rafael Jodar and I noticed he doesn't have a big game. He does like to take the ball early and he is effective on grass.

A big underdog always needs to start well - and that has been the case.

It's a confident start from Shintaro Mochizuki whose serves are on point, leaving Jannik Sinner little to work with.

The Japanese world number 151 holds to 15 and that will do his confidence a world of good.

It's the world number one in Jannik Sinner against the world number 151 in Shintaro Mochizuki.

Before Wimbledon, Mochizuki had failed to claim a single tour-level win this season - losing all six matches - but the 23-year-old heads into this fourth-round meeting seeking an unlikely seventh straight victory.

We're under way on Centre Court.

Felix Auger-Aliassime is a game away from a quarter-final against Novak Djokovic - but two match points have already gone begging.

The Canadian third seed held his own serve with a minimum of fuss and then moved to 15-40 on Alejandro Davidovich Fokina's serve.

He gets a look at a second serve on the second of them and seems in control of the point before thumping a backhand into the net.

Davidovich Fokina then produces a fantastic backhand winner, on the run, to secure the hold. The Spaniard is hanging in there.

After victories in 2021 and 2022, Britain's Neal Skupski and American partner Desirae Krawczyk have taken another step towards a third Wimbledon triumph in the mixed doubles.

There's still a long way to go but the sixth seeds have beaten Francisco Cabral of Portugal and Australia's Ellen Perez in three sets, 7-6 (7-5) 4-6 6-3, to progress to the third round.

Liverpudlian Skupski is targeting a fifth Grand Slam triumph after winning the men's doubles at SW19 in 2023 and taking the title in the same event at the Australian Open earlier this year.

Two quick games as Felix Auger-Aliassime and Alejandro Davidovich Fokina exchange comfortable holds.

The former will be happy to continue that pattern as he remains a break up in this fourth set and is just two games away from booking his place in the quarter-finals.

A reminder that Novak Djokovic is awaiting the winner of this one.

Top seed and defending champion Jannik Sinner continues his quest for a fifth Grand Slam when he faces Japan's unseeded Shintaro Mochizuki on Centre Court shortly.

After overcoming a scare against Miomir Kecmanovic in the first round, Sinner has showed glimpses of his imperious best with two straight sets wins to reach the last-16.

Mochozuki is into the fourth round at a Grand Slam for the first time after beating 23rd seed Rafael Jodar in an impressive third-round performance.

The match marks the first ever meeting between the pair.

Four-time Grand Slam winner Naomi Osaka, speaking on Centre Court after knocking out top seed Aryna Sabalenka: "It was a really fun match. I'm really grateful. Even if I lost, I would still think it was a great match. For me, this court is so special and this is the first match I've won on it so it means a lot. Thank you guys so much, I really appreciated the atmosphere. My mum is over there, she cooks a lot and I feel like her cooking is powering me so I would really appreciate another meal tonight! She cooks a bunch of Japanese food, so shout out Japanese food. It has been a long time since I've had so much fun on the court, so to do it here means a lot. Going into this match, I had lost to Aryna [Sabalenka] three times in a row. I wanted to turn it over and I'm really glad I had the opportunity to do that."

On the reason behind her looking much more comfortable on the grass: "The big Polish man! Shout out Tomasz [Wiktorowski]! Also a shout out to the rest of my team, they are the best team ever. I have so much fun with them and I learn so much from them, I'm so grateful they are on this journey with me."

Naomi Osaka is the first player to defeat Aryna Sabalenka in straight sets at a Grand Slam since Victoria Azarenka at the US Open in 2020.

Naomi Osaka is speaking on court now, we'll bring you her full interview very soon.

She has paid thanks to her mum for keeping her fuelled with Japanese food and also thanked her coach Tomasz Wiktorowski for getting her playing at such a high level once again.

Wiktorowski has a history of helping players to win Grand Slam titles - he worked with Iga Swiatek when she lifted four of them between 2022 and 2025.

Czech 10th seed Karolina Muchova is next up for Osaka in the quarter-finals.

You've got to feel a bit for Alejandro Davidovich Fokina.

He's had a total of six break points in this match and not been able to convert any of them.

On serve he's just played a point that's lit up Court One, diving one-handed like a goalkeeper at the net to win the point, before securing the hold.

The women's draw is wide open. There is so much depth in the draw now.

That was such a well-deserved result for Naomi Osaka. It wasn't that Aryna Sabalenka played poorly, she tried to slice and she tried the serve and volley a little. Osaka was just able to stay in that high level from the first set throughout the second set as well. She maybe even got better.

That was such great intent and control. She kept the unforced errors down and hit 21 winners. This coach has really done a phenomenal job of rounding out her game and convincing her that her game works out well on grass.

Awesome Osaka!

An unbelievable performance from the four-time major champion. What a way to book your place in a first Wimbledon quarter-final.

Another big name in the women's draw falls. The top seed, I'm afraid, is out.

Naomi Osaka is playing at such a high level at the moment.

She is through to the quarter-finals of Wimbledon for the first time in her career and has achieved that feat at the expense of the top seed... in straight sets!

Can anyone stop Osaka?
