Next up on Arthur Ashe will be men's world number one Novak Djokovic.

The Serb continues his pursuit of a calendar Grand Slam against Japan's Kei Nishikori.

We'll follow that one when it gets under way, as Andreas Seppi is on course to take Oscar Otte to at least a fourth set on court 17, where it appears Emma Raducanu will have to wait a little bit longer.

Fingers crossed for more scenes like these today. The US Open crowd have certainly got behind Emma Raducanu so far.

Emma Raducanu only qualified for her first major last week, but she remains totally unfazed by the magnitude of playing in her first overseas Grand Slam.

The 18-year-old delivered yet another impressive display as she swept aside China's Zhang Shuai to book her place in the US Open third round.

Raducanu won 6-2 6-4 in one hour and 21 minutes against 32-year-old Zhang, who is ranked 101 places higher than the 18-year-old.

After a stunning run to the last 16 on her major debut at Wimbledon, can she match that achievement in New York?

On Arthur Ashe, Greek 17th seed Maria Sakkari is closing in on victory against Czech 10th seed Petra Kvitova. She leads by a break in the second set after taking the first.

And on Louis Armstrong, Swiss 11th seed Belinda Bencic is also a set and a break to the good against American Jessica Pegula, after Canadian sixth seed Bianca Andreescu earlier defeated Belgian Greet Minnen in straight sets.

Elsewhere, Italian men's sixth seed Matteo Berrettini is tied at one set all against Ilya Ivashka, while German Oscar Otte is now two sets up against Andreas Seppi on court 17.

James Stevenson: Tennis needs new stars as the old ones/the greats begin to wind down. Carlos Alcaraz looks like he is the real deal. Hopefully Great Britain’s 18-year-old can do what he did.

Naomi Osaka's US Open title defence is over, however.

The world number three lost her third round match against another talented teenager in Canadian 18-year-old Leylah Fernandez 5-7 7-6 (7-2) 6-4.

Afterwards, Osaka - who withdrew from this year's French Open after revealing she has struggled with her mental health since first becoming a Grand Slam champion in 2018 - said she will take another break from tennis.

"I feel like I'm kind of at this point where I'm trying to figure out what I want to do," Osaka said.

"I honestly don't know when I'm going to play my next tennis match. I think I'm going to take a break from playing for a while."

What a night it was on Arthur Ashe Stadium for Spanish teenager Carlos Alcaraz.

In a dazzling display, the 18-year-old claimed a fifth set tie-break to stun Greek third seed Stefanos Tsitsipas in a thrilling third-round encounter - prevailing 6-3 4-6 7-6 (7-2) 0-6 7-6 (7-5) to set up his first Grand Slam fourth-round appearance.

Alcaraz, the youngest man to reach the US Open fourth round in 32 years, said: "I think without this crowd I haven't the possibility to win the match. I was down at the beginning of the fourth set so thank you to the crowd for pushing me up in the fifth.

"It's an incredible feeling for me. This victory means a lot to me. It's the best match of my career, the best win, to beat Stefanos Tsitsipas is a dream come true for me."

There will be at least one Brit in week two, after British men's number one Dan Evans produced a gritty comeback from two sets down to beat Australian Alexei Popyrin.

Evans somehow found a burst of energy in the final set tie-break to win 4-6 3-6 6-3 6-4 7-6 (7-1) in four hours and seven minutes, advancing to the US Open fourth round for the first time.

Evans dropped to his haunches in disbelief as his victory was confirmed on a Popyrin double fault. Up next for him will be Russian world number two Daniil Medvedev.

Emma Raducanu's match against Sara Sorribes Tormo is second on court 17, after Andreas Seppi against Oscar Otte.

Otte is currently a set and a break up, so if the German can continue to dominate we may not have too long to wait before the Briton takes to the court.

Britain's Joe Salisbury, Jonny O'Mara and Neal Skupski are all doubles action today too.

In the mixed doubles second round, second seeds Salisbury and American Desirae Krawczyk take on Filip Polasek of Slovakia and Switzerland's Belinda Bencic, while Skupski and Chilean Alexa Guarachi meet Serbian Nikola Cacic and Kazakh Galina Voskoboeva.

In the men's doubles second round, O'Mara and Aisam-ul-Haq Qureshi of Pakistan face Belgians Sander Gille and Joran Vliegen.

First, let's take a look at what else is to come on Saturday at the US Open.

Women's world number one Ashleigh Barty faces American Shelby Rogers on Arthur Ashe Stadium, after men's top seed Novak Djokovic takes on Japan's Kei Nishikori.

Women's 10th seed Petra Kvitova and 17th seed Maria Sakkari are already under way on the main stage, while elsewhere in the women's draw Czech fourth seed Karolina Pliskova meets Australian Ajla Tomljanovic.

In the men's draw, German fourth seed Alexander Zverev plays American Jack Sock, Italian sixth seed Matteo Berrettini faces Belarusian Ilya Ivashka and Canada's seventh seed Denis Shapovalov is up against South African Lloyd Harris.

It was another thrilling day at the US Open on Friday, as Britain's Dan Evans recovered from two sets down to reach the fourth round of the New York Slam for the first time.

Today, on the same court, British 18-year-old Emma Raducanu will attempt to reach the last 16 as she takes on Spain's Sara Sorribes Tormo.
