What's happened so far?

So, what has gone on so far on day four, I hear you ask.

Well, the big shock of the day saw seventh seed Grigor Dimitrov knocked out by 19-year-old Russian Andrey Rublev.

World number one Karolina Pliskova almost suffered the same fate but came from behind to beat American Nicole Gibbs.

The first match on Arthur Ashe saw fourth seed Elina Svitolina progress while French Open champion Jelena Ostapenko is also into round three with her victory over Sorana Cirstea on Louis Armstrong.

Juan Martin del Potro's bid for a second US Open title continues as he won today but 15th seed Tomas Berdych is out. He lost to Alexandr Dolgopolov.

Another notable match saw American Shelby Rogers beat 25th seed Daria Gavrilova in the longest women's singles match in US Open history. It lasted three hours and 33 minutes.

It is huge for the Federer team and huge for the tournament. He did a good job. He toughed it out. He is not playing well but is still in the tournament. He has still got motivation which is so important.

Still to come

The night session will get going shortly on Arthur Ashe Stadium.

Big-hitter Coco Vandeweghe will be on from 00:00 BST as she faces Tunisia's Ons Jabeur, before Rafael Nadal plays Taro Daniel.

American Madison Keys is still to come on Louis Armstrong Stadium against Tatyana Maria, while Svetlana Kuznetsova is last on Grandstannd Court against Kurumi Nara.

And Agnieszka Radwanska has just got her second-round match against Yulia Putintseva under way on court 17.

An update on that last entry - Thiem is through after winning the fourth set against Fritz 7-5.

Elsewhere at Flushing Meadows...

It's all been about what was happening on Ashe for the past few hours but a quick update on what's going on elsewhere...

Sixth seed Dominic Thiem leads Taylor Fritz two sets to one and it's 6-5 to Thiem in the fourth on Louis Armstrong.

Gael Monfils and Donald Young are into a fifth on Grandstand - it's 3-3 in the decider.

David Goffin is two sets to one down against Guido Pella - it's 6-5 to Goffin on serve in the fourth.

It makes it more difficult but he won three five setters in Melbourne to win the title. If he gets through the next matches quicker, which is more difficult, then he will be alright.

Federer might not give much away in the post-match interviews but it will be interesting. He doesn't play long five-set matches. This was just over three hours.

It's another 35-year-old next for Roger Federer - Feliciano Lopez, who overcame fellow Spaniard Fernando Verdasco in four sets today.

Federer's record against Lopez isn't quite as good as against Youzhny but it's still pretty formidable - 12-0.

But would you be confident putting any money on the Swiss after that display?

'I feel warmed up by now'

Roger Federer speaking after his victory over Mikhail Youzhny: "The five-set battles are a lot of fun. I feel warmed up by now.

"I haven't played a lot of guys with cramps and the new rules have changed. You are not allowed to get support from the physio so it is hard to watch.

On Youzhny's cramp: "I feel for him. We go way back to the '98 juniors when we played doubles against each other. This was probably our best match so it was fun out here."

Leon Smith

It was amazing entertainment. It was not about the level. It was up and down from Roger and there was bravery from Youzhny who responded so well after the first set. Federer handed the initiative and Youzhny's confidence grew.

A total of 68 unforced errors for Federer, to go with 56 in his first-round match.

There's work to be done on the Federer backhand.

Federer served and hit forehands well, but hit just 7 backhand winners vs 35 backhand unforced errors. Will need to improve, quickly.#usopen

Only Jimmy Connors, with 98 victories, has won more US Open matches than Roger Federer.

It's some record.

Federer still looks fresh as he goes through the post-match routine. No questions about his back from the interviewer, though...

Federer hangs over the net exhausted. He might not be fully fit but he's still here.

Federer 6-1 6-7 (3-7) 4-6 6-4 6-2 Youzhny

Mikhail Youzhny departs to cheers from a stadium that seemed to be against him from the very beginning.

That's Federer's 80th win at Flushing Meadows.

Game, set and match - Federer

He's done it!

An almighty match and Roger Federer raises his arms to the Arthur Ashe Stadium. He's through to the third round of the US Open after an engrossing three-hour battle.

Match point two

Federer 6-1 6-7 (3-7) 4-6 6-4 5-2 Youzhny*

Oh! Glorious from Federer, up on one leg and spanking the ball into the corner of the court. Can he do it on this one?

Deuce again

Federer 6-1 6-7 (3-7) 4-6 6-4 5-2 Youzhny*

That serve, though.

Federer can't pick it up and he backhands his return straight into the net. He goes long from out wide, though, and we're back to 40-40.

Federer 6-1 6-7 (3-7) 4-6 6-4 5-2 Youzhny*

Into the net goes Federer! A nothingy forehand finds the net. Deuce.

Match point for Federer

Federer 6-1 6-7 (3-7) 4-6 6-4 5-2 Youzhny*

Hello, here's match point as a Youzhny backhand goes long...

Deuce

Federer 6-1 6-7 (3-7) 4-6 6-4 5-2 Youzhny*

A double fault again from Youzhny. That cramp has really stuffed his serve - he can't get any momentum into it.

He's on the board though as two Federer backhands go wide. Federer's really not got to grips with that serve today. The lack of pace hasn't suited him at all.

40-15 comes up as a Federer backhand finds the net once again, but then Federer unfurls two fine forehands to force deuce.

Federer 6-1 6-7 (3-7) 4-6 6-4 5-2 Youzhny*

If you'd have told me three hours ago that this match would go to five sets and that Mikhail Youzhny's backhand would be making Roger Federer's look ordinary, I'd have probably had a good old chuckle at your expense.

But here we are. What a match. Odd and yet enthralling. And here he is. A game away from victory.

Leon Smith

Great Britain Davis Cup captain on BBC Radio 5 live sports extra at Flushing Meadows

I feel for Youzhny. He is not shy of putting the work in. It is not like you should say he needs to hit the gym.

He has always been a very good professional. It is a shame to see him like this. If I was in his box I would be oozing with pride.

Federer holds

How do you consolidate a break?

With your second love hold of the set, that's how. Roger Federer is a game away from the US Open third round.

Federer breaks

*Federer 6-1 6-7 (3-7) 4-6 6-4 4-2 Youzhny

Oh, Mikhail. A double fault hands Federer the break. He's fading now but what a performance this has been.

*Federer 6-1 6-7 (3-7) 4-6 6-4 3-2 Youzhny

The umpire calls "out" to a Federer backhand, he challenges - and it's in! Arthur Ashe boos her and she raises her hand in apology to the crowd.

Youzhny saves first break point

*Federer 6-1 6-7 (3-7) 4-6 6-4 3-2 Youzhny

Ace down the T to get yourself on the board. As you do.

*Federer 6-1 6-7 (3-7) 4-6 6-4 3-2 Youzhny

A drop shot from Federer forces Youzhny to come running forward - I'm not entirely sure Federer intended that but it's worked, bouncing twice before Youzhny can get near it.

And now long on the forehand from the Russian! Three break points to Federer...

Federer 6-1 6-7 (3-7) 4-6 6-4 3-2 Youzhny*

He is. He's clearly not 100%, it's getting harder to serve and Federer's trying to make him run around like a puppy in a park.

Where's your money going, folks?

Leon Smith

Great Britain Davis Cup captain on BBC Radio 5 live sports extra at Flushing Meadows

Youzhny is showing such bravery here.

Double fault from Federer hands Youzhny the first points of the game, but Youzhny swats his next forehand wide cross-court. Plenty of oomph behind that, just not much direction.

That's a glorious strike down the line from Federer, a beautiful backhand volley that just kisses the line, before Youzhny sails his response wide.

Game, Federer.

Ant Steel: People forget Federer is a stone-cold competitor, along with his grace. Fed is the King.

Abu Ali: There could be a MASSIVE upset here......and the crowd is dead silent. So strange!

Youzhny saves two break points & holds

*Federer 6-1 6-7 (3-7) 4-6 6-4 2-2 Youzhny

That's an almighty second serve from Youzhny, and Federer nets.

And, finally, the game ends as Federer's forehand goes long.

The way Youzhny is walking it is amazing what he is managing to do in the rallies.

Federer 6-1 6-7 (3-7) 4-6 6-4 2-1 Youzhny*

Federer mis-hits a backhand but Youzhny does the same, and that brings up the second break point.

Oh! Federer fluffs it again! Down the line goes Youzhny, Federer unfurls the backhand - and nets. To the sixth deuce we go.

Youzhny saves break point

Federer 6-1 6-7 (3-7) 4-6 6-4 2-1 Youzhny*

Break point Federer! Youzhny sails his backhand into the net. This is the first break Federer has had...

And, my word, he's overcooked that! Youzhny, working with just one leg, gets down low and spanks a forehand back that Federer sends wide.

Leon Smith

Great Britain Davis Cup captain on BBC Radio 5 live sports extra at Flushing Meadows

I think the cramp is starting to go through Youzhny's arm.
