They say there's no rest for the wicked and that's certainly the case for Ben Shelton. The American has played all but one day since Wimbledon started on Monday with all three of his matches going the distance.

The 14th seed takes on world number one Jannik Sinner on Court One today and Shelton is ready.

"They say it's best of five sets so you might as well use all of them this week and it's worked out pretty well," he told BBC Sport.

"I know what I want to do out there on that court. I know what I'm good at and I'll work hard to be in the situations I want to be in when I'm playing out there. I'll have a lot of fun, I'll enjoy it."

I think Shelton is made for the grass, which is what makes him so dangerous.

They are literally the same age but such a difference to what they've experienced.

His whole experience has been based around college tennis and he is really experiencing what it is like to be on tour, and to be able to deal with that.

Wonder why these guys are knocking around Wimbledon today?

The Carota Boys have become minor celebrities themselves since following Jannik Sinner's every move.

Here they are stood in front of the Fred Perry statue outside Centre Court, posing for photographs and selfies with fans.

Expect to see them on Court One shortly...

Ugo Humbert is not going anywhere.

A brilliant return flies past Carlos Alcaraz as he slips and the Frenchman has two break back points.

Another fine return is too much for Alcaraz to handle and we're back on serve in the fourth. Remarkable.

It is so completely different in here. It feels a lot more like a sauna and who does it suit? I would say Sinner.

Aged just 21, Ben Shelton is already well on track to surpass the achievements of his father and former tennis professional Bryan.

The American 14th seed confirmed his place in round four at Wimbledon on Saturday with a 6-7 (4-6) 6-2 6-4 4-6 6-2 victory against Canada's Denis Shapovalov.

Bryan, who coaches Ben, made six appearances at Wimbledon during his playing career, with his best run coming in 1994 when he reached the fourth round.

Ben faces a very difficult task in booking a spot in the quarter-finals with world number one Jannik Sinner standing in his way on Court One today.

Carlos Alcaraz has just got to regroup and that's exactly what he's done with that early break in the fourth.

Carlos Alcaraz had three break points, he only needs one.

A fierce return and Ugo Humbert puts his shot into the net.

Ben Shelton only turned professional in August 2022 but he is already making his mark on the sport.

In 2023, Shelton reached the quarter-finals of the Australian Open and the semi-finals of the US Open.

His run to the last four on home soil saw him beat 2020 US Open champion Dominic Thiem and compatriot Frances Tiafoe, who was seeded 10th, before losing to eventually winner Novak Djokovic.

Shelton won his first ATP Tour title at the Japan Open in October and entered Wimbledon ranked number 14 in the world.

He's looking to make a major statement today against world number one Jannik Sinner in their first encounter on grass.

The pair have met three times previously - all on hard courts - with Shelton winning one and Sinner coming out on top in the other two.

Will Carlos Alcaraz respond? It was a silly question really, wasn't it?

The Spaniard quickly moves up 0-40 on the Ugo Humbert serve to bring up three break points.

Jannik Sinner started 2024 on a positive note by winning the Australian Open and has since established himself as the world number one - the first Italian to achieve that feat.

Topping the rankings comes with an added bit of pressure to perform and put on a show but Sinner is taking it all in his stride.

Since being named world number one on 10 June - just days after exiting the French Open in the semi-finals - Sinner has lifted the Halle Open title and made pretty easy work of his opponents to reach round four at Wimbledon.

The 21-year-old needed just 21 minutes to take the opening set against Serbia's Miomir Kecmanovic in round three before going on to wrap up a straight set win in one hour and 38 minutes.

Fantastic backhand from Ugo Humbert to give him another break and the third set.

Carlos Alcaraz can only watch as the ball lands on the line and Humbert's team jump up in celebration in the coaches box.

Can the Frenchman keep this momentum going in the fourth or will we see a response from Alcaraz?

Ugo Humbert has decided to step it up a level and Carlos Alcaraz is looking a bit flustered.

The defending champion is making unforced error after unforced error, while Humbert is slamming home winners like they're going out of fashion.

Two brutal aces from the Frenchman shows exactly how he is feeling.

An ace out wide seals the simplest of service games for Ugo Humbert.

The big left-hander is now just a game away from taking the third set.

For the first time in 20 years, seven Americans will feature in the fourth round at Wimbledon.

Coco Gauff, Ben Shelton, Emma Navarro, Taylor Fritz, Tommy Paul, Madison Keys and Danielle Collins are all involved in the second week at SW19.

Keys' journey came to an end in a emotional circumstances just a few moments ago after she was forced to retire from her fourth round match against Italy's Jasmine Paolini due to injury in the deciding third set.

But one American is guaranteed to be in the last eight with compatriots Gauff, who is the highest seed remaining in the women's draw, and Navarro meeting in the final match on Centre Court today.

If Shelton, 21, manages to overcome world number Jannik Sinner in the next game on Court One, he will become the youngest American man reach the quarter-finals at SW19 since Andy Roddick in 2003.

You have to go all the way back to Pete Sampras in 2000 for the last time an American was crowned men's singles champion and Serena Williams was the last American woman to lift the Venus Rosewater Dish in 2016.

Will an American get their hands on either trophy this year?

Italian seventh seed Jasmine Paolini speaking on court after her victory over Madison Keys:

"I'm very sorry for her. It's sad. Really good match. Really tough, lots of up and downs. I feel a bit happy but also sad for her because it's not easy to win like that. I hope you enjoyed the match.

"Roller coaster. I started really well and was really focused on court but she's a great player and she raised her level so it was tough to return balls. I was repeating to stay in there, you never know in tennis. At the end somehow, I know she retired, but I'm here with the win.

"I hope so. I love this court. Thank you for the support and for all the Italians that are here there are so many. I'm enjoying it a lot."

Ugo Humbert really has continued to go after the return of serve.

Top quality hitting from Humbert. He hasn't let his head drop in any way and he is getting his rewards in this third set.

Ugo Humbert is fired up.

He's playing brilliantly now, giving Carlos Alcaraz no easy points and when the Spaniard sends a forehand wide, the 16th seed has a double break.

Carlos Alcaraz advances but puts his forehand into the net to hand Ugo Humbert the chance of a double break.

The world number three is looking a little flustered for the first time.

No dramas for Ugo Humbert as he holds to 15 and consolidates the break.
