Right, I’m going to wrap things up there. We’ve got plenty more coverage over the next fortnight so don’t run too far away. Thanks for reading.

Jacob Fearnley re-watches the smash he messed up while on match point: “It was starting to rain as well, the rain was getting a little bit in my eyes,” he tells Sky. Nonetheless, he did a decent job moving on from it.

Does Fearnley still have those two match points on his mind? Looks like he’s moved on: he nails the forehand smash this time round to make it 30-all on Landaluce’s serve. The Spaniard holds to 30, and it’s time for Fearnley to serve for the match – again. He leads 4-6, 6-2, 4-6, 7-5, 5-3.

It gets even better for Fearnley, who has three chances to break Landaluce’s serve. The Spaniard sends down an ace but then nets a forehand. Fearnley, 5-1 up in the fifth set, will serve for the match – and he’s in a rush. A sharp backhand winner is followed by a forehand that’s placed even better. He has two match points and messes up the first in comical style, completely missing a forehand smash! And then a wide forehand takes us to deuce! And then a double fault! Yikes!

Landaluce doesn’t convert the break point, but he’s got another after Fearnley double-faults again – and the Briton goes long! We’re not done just yet. Fearnley leads 4-6, 6-2, 4-6, 7-5, 5-2.

Great Britain’s Jacob Fearnley is deep into a five-setter … and it’s going his way. He’s 4-1 up in the deciding set against Martín Landaluce, who is down a break.

Well, what’s happened here? Stan Wawrinka was down 5-3 – he’s now 6-5 up in the first set against Matteo Berrettini. The Italian is serving, stuck on deuce, but he eventually takes us to a tie-break.

Wawrinka brushes the net cord with a forehand winner before his one-handed backhand goes long. Berrettini goes 3-2 up before unleashing a monster serve, setting him up for an advance to the net and a thumping forehand. Wawrinka, 41 years young, levels up – he runs his opponent ragged before finishing with a cool backhand drive down the line.

Nonetheless, Berrettini wins the tussle, sealed with a rollicking forehand. The 2019 US Open semi-finalist takes the first set 7-6 (4).

Stefanos Tsitsipas has spoken to Sky about his impressive victory against the in-form 10th seed Arthur Fils.

Today I feel like I wasn’t thinking too much, which was a great thing – I played simple tennis, I wished it would work … and the philosophies during the match? Not too many.

If the serve goes well, on the line, perfect. I don’t think I can do that every single point. I was on an 80% mentality – I wasn’t striving for 100%.

Stan Wawrinka, playing in the final grand slam of his career, is in action on Grandstand against Matteo Berrettini – the pair met at Wimbledon this year, with Wawrinka taking the first set before Berrettini recovered to win in four. It’s 10 years since Wawrinka triumphed at Flushing Meadows for the third and final slam of his career, beating Novak Djokovic in the final. Berrettini is a break ahead in the first set, leading 5-3.

Alcaraz steps up to the mic and talks about his absence from the court.

It’s been a really tough five months for me so being able to step in the Arthur Ashe, to compete again … here in New York it’s a really special place for me, a really special tournament for me … I missed the crowd’s energy, I missed competition, I missed everything. I’m just really, really happy that I was able to compete again.

At 15-30, Alcaraz is in a tiny spot of bother … but a backhand volley is his mode of escape. A massive serve extends Alcaraz’s lead to 6-4, 6-4, 5-3.

Safiullin holds to 30 but we’re waiting for the inevitable. Alcaraz leads 6-4, 6-4, 4-3.

Alcaraz doesn’t nail a drop shot and Safiullin has enough time to get to it and hit a deft winner. It’s just a consolation, though – Alcaraz rushes through his service game. He leads 6-4, 6-4, 3-1.

Safiullin sends an ace straight down the middle but nets a backhand to hand Alcaraz a break point. Alcaraz pings a forehand to the corner and Safiullin is in no position to deliver a clean backhand in response. He finds the net again and Alcaraz has control of the third set, too. Alcaraz leads 6-4, 6-4, 2-1.

Here’s a little twist: Safiullin has two chances to break. A whippy Alcaraz forehand denies him the first and the Russian goes long with the second. A double fault by Alcaraz hands Safiullin a third break point … but the Spaniard is granted time to slap another forehand winner. Alcaraz escapes: he leads 6-4, 6-4, 1-1.

Safiullin kicks-off the third set on his serve and holds to 30, keeping his cool on the final point at the net despite Alcaraz’s impressive defence. Alcaraz leads 6-4, 6-4, 0-1.

Safiullin and Alcaraz have both left the court so it’ll be a little wait until that third set gets started. The Russian has reached the second round at Flushing Meadows three years in a row – we’re on for an all-timer if he makes it four.

Hello again, folks. Alcaraz, the sliding menace, delivers a deft volley before a show of power takes him to set point. He overdoes a cross-court forehand, taking us to deuce. But a forehand down the line is followed by a wide forehand by Safiullin. Alcaraz claims the second set and leads 6-4, 6-4.

My work here is done – Taha is back.

*Safiullin 4-6, 3-5 Alcaraz (*denotes next server)

One game away from 2-0 in sets for Alcaraz.

Safiullin 4-6, 3-4 *Alcaraz (*denotes next server)

Like clockwork. The singlet-sporting Spaniard seals a precious break in the often-crucial seventh game of the set, just as he did in the first. Safiullin is battling admirably but all the signs are that Alcaraz is going to have too much.

It’s quickly 0-30 on the Russian’s serve.

“Alcaraz sensing the opportunity in this seventh game,” observes Tim Henman on commentary.

*Safiullin 4-6, 3-3 Alcaraz (*denotes next server)

Even stevens.

If you missed it … Tumaini Carayol on Novak Djokovic’s abrupt exit:

The first night session of the US Open this year was approaching the three-hour mark when Novak Djokovic walked briskly to the corner of the vast Arthur Ashe Stadium court, bent down and vomited the contents of his stomach straight into the towel bin.

Safiullin 4-6, 3-2 *Alcaraz (*denotes next server)

The Russian is ranked 99 in the world, and Alcaraz is No 3, but the underdog is putting up a good fight here and he holds serve for 3-2 in the third.

Of course, Safiullin would have hoped that Alcaraz would perhaps not be at his best after a long injury absence.

Also in the men’s singles: Alex Michelsen (USA) v Federico Cina (Italy).

Looks like Michelsen fans will be dancing in the streets this evening, because he’s romping home at is stands: 6-4, 6-1, 3-0.

*Safiullin 4-6, 2-2 Alcaraz (*denotes next server).

All square in the second set on Arthur Ashe.

Safiullin had a sniff of 3-0 moments ago, but Alcaraz breaks back for 2-1.

Over on Court 12, Britain’s Jacob Fearnley is taking on Martin Landaluce of Spain, in a match they started yesterday but was delayed due to rain.

Fearnley has just taken the second set, which makes the scores on the doors: Landaluce 6-4, 2-6 Fearnley

Safiullin 4-6, 1-0 *Alcaraz (*denotes next server).

Safiullin 4-5 *Alcaraz (*denotes next server).

Safiullin produces a sumptuous volley, coming to the net, to buy himself advantage. He saves two break points and forces the Spaniard to serve it out …

Anna Kalinskaya (seeded 21) is 5-4 up on Anna Blinkova in their first set on Court 5.

And now a set point for the 23-year-old Spaniard.

The commentators are discussing Alcaraz’s outfit. His top is a brown singlet-type number, with little left to the imagination.

*Safiullin 3-5 Alcaraz (*denotes next server).

Again it’s a bit of a struggle on serve, again he gets the job done. Safiullin must serve to stay in this first set.

Now deuce on the Alcaraz serve …

Sunday had become Monday by the time Venus Williams finally emerged beneath the closed roof of Arthur Ashe Stadium, her entrance pushed deep into the night after Novak Djokovic’s bruising defeat by Argentina’s Mariano Navone went the five-set distance. The first ball was struck at 12.13am, the latest start to a match in US Open history, yet several thousand spectators remained to watch a player who has been part of this tournament for as long as the building itself.

“You can definitely tell there’s some rust,” says the Sky Sports pundit Laura Robson of Alcaraz, who has been out injured for four months with a wrist problem.

“I think is he a bit undercooked physically, perhaps … you can’t replicate this intensity on the practice court.”

Safiullin 3-4 *Alcaraz (*denotes next server).

First blood to the Spaniard: he wastes one break point, but takes the second with a searing 108mph forehand winner. Boom!

Break points for Alcaraz in the seventh game: it’s 15-40 …

*Safiullin 3-3 Alcaraz (*denotes next server).

It stays with serve on Arthur Ashe Stadium.

The seven-times grand slam winner, Alcaraz, is taken to deuce in his second service game. He closes it out after a minor scare.

Safiullin 1-0 *Alcaraz (*denotes next server). The Russian holds, and it’s the Spaniard’s turn.

Carlos Alcaraz is out on court, and knocking up against Roman Safiullin of Russia.

Men’s singles: Matteo Arnaldi (30) v James Duckworth is go on Court 10. Duckworth holds serve to begin.

Thanks Taha, hello all.

And with that, I’ll hand over to Luke McLaughlin for the next couple of hours.

Osorio is forced into the splits by Sabalenka’s net play, and the No 1 seed has the chance to break … Osorio has control of the rally but misplaces a backhand to the corner. Sabalenka’s not had the best time in this second set but has the chance to wrap things up now. She leads 6-2, 5-4.

Sabalenka is in the shade on Arthur Ashe as she launches her serves, but Osorio is finding joy in the light, visibly more confident in this second set. Sabalenka does hold as she leads 6-2, 4-4.

Sabalenka has 20 unforced errors in the match; Osorio is on 15. This looked straightforward after the first set but the world No 59 is hanging in there. Sabalenka leads 6-2, 3-4.

Sabalenka is in trouble, down 30-40 … but a backhand down the line lets her roar. Osorio whips a cross-court return and has another chance to break … but another backhand down the line saves Sabalenka, who – eventually – manages to hold. She leads 6-2, 3-3.

Osorio’s finding her flow! She completes her hold by advancing to the net and nailing a backhand drop, her finest stroke of the match. Sabalenka leads 6-2, 2-3.

And Osorio breaks back, with Sabalenka totting up several unforced errors. The 28-year-old overcooks a few of her groundstrokes on Osorio’s serve and the Colombian finds herself ahead in the second set. Sabalenka leads 6-2, 1-2.

Sabalenka shifts Osorio from side to side before the power-packed forehand to close the points. Sabalenka converts her second break point of the game when Osorio, back-pedalling, forehands into the net. The first seed leads 6-2, 1-0.

Sabalenka takes the first set 6-2, with five aces and 18 winners so far. It’s all rather predictable.

Wonderful from Sabalenka. She pummels Osorio’s second serve before advancing to the net, a deft forehand toying with her opponent. And, just like that, she’s broken back. Sabalenka goes 5-2 up and is serving for the first set.

Sabalenka is cruising, breaking for the second time to go 4-1 up against Osorio. The defending champion is angry with herself, though, after a backhand finds the net. An ace swiftly follows but Sabalenka’s balance is off with her backhand – Osorio has two break points. Sabalenka stays calm at the net to save the first with a forehand smash but then double-faults! Osorio has the break; Sabalenka leads 4-2.

Arthur Fils has taken the first set against Stefanos Tsitsipas 6-4, while Karolina Muchova is sprinting to the second round – she’s up 6-3, 5-0 against Sinja Kraus.

Osorio finds some confidence with a couple of crushing winners before Sabalenka saves a break point with an ace. Sabalenka’s serves down the middle do the job as she goes 3-1 up in the first set.

Sabalenka fires a backhand to take Osorio to deuce. Osorio double-faults once again before showing off a steely defence against her opponent’s phenomenal power, with Sabalenka eventually pummelling the net. But Osorio serves consecutive double faults – that’s five in the match – to gift Sabalenka the break. The world No 1 goes 2-1 up.

Sabalenka eases through on her serve, advancing to the net to secure her first game of the tournament with a forehand volley. It’s 1-1 in the opening set against Osorio.

Sabalenka and Osorio are underway on Arthur Ashe, with the Colombian serving. She records two double-faults before Sabalenka seizes upon the second serve, whipping a blistering forehand to make it deuce. But the defending champion finds the net and the stratosphere, too, as Osorio holds to go 1-0 up.

Back to Tsitsipas v Fils, and the latter has the chance to break … he goes long with a backhand and we’re back to deuce, with Fils leading the first set 3-2. Tsitsipas pushes forward to swat a forehand winner and a big serve gives him the game. 3-3 it is.

Britain’s Harriet Dart is up against Peyton Stearns, who plays a deft backhand volley to hold her serve and go 2-1 up. Over on Grandstand Karolina Muchova, runner-up at Wimbledon this year and seventh seed here, is leading 4-1 against Sinja Kraus.

Fils, the 10th seed, finds himself stuck on deuce while serving against Tsitsipas – but the Frenchman saves three break points before a backhand down the line gives him the opening game.

Arthur Fils, who claimed his first Masters title this month by beating Frances Tiafoe in Cincinnati, has an intriguing opening clash. He’s up against two-time grand slam finalist Stefanos Tsitsipas on Louis Armstrong.

Here’s more on Sabalenka by Tumaini:

Such is the competition at the top of women’s tennis, her rivals are congregating at her front door. Elena Rybakina begins this tournament sitting at No 1 in the live standings and in control of her own destiny. Sabalenka must win the title to have any hope of retaining the top ranking, but Rybakina will become the new No 1 regardless of all other results if she reaches the semi-finals. Should either Coco Gauff or Jessica Pegula win the title and Rybakina fails to make the semi-finals, they would take top spot. This additional pressure could further add to Sabalenka’s woes, but perhaps, after 97 consecutive weeks as the undisputed best player in the world, this is exactly what she needs.

Aryna Sabalenka will be up on Arthur Ashe at 11.30am EDT (4.30pm BST). She’s met Camila Osorio twice, winning in straight sets on both occasions, the first of those at Wimbledon in 2021. The world No 1 is the defending champion and triumphed in 2024 too – but she’s had a tough time of it recently. Sabalenka lost in the round of 16 at the Cincinnati Open to Sara Bejlek and hasn’t reach a final since winning the Miami Open in March. Maybe a return to New York, where she’s had so much success, will bring the rhythm back.

A 12.13am start! It’s a no from me.
