The players are knocking up on court, having tossed the coin to the blaring slap-bass stylings of the Red Hot Chilli Peppers.

"Three minutes gentlemen," calls the umpire.

Still a fair few blue seats to be filled on Arthur Ashe.

And the good news.

Thomaz Bellucci has lost his last 14 matches against top-10 ranked opponents.

He has reached the fourth round of a Grand Slam only once in 27 attempts.

Murray by contrast has reached the quarter-finals at least of the last 18 Grand Slams he has entered.

A fully-focused, fit and firing Murray should wrap this one up without too much fuss.

Let's start with the bad news.

Thomaz Bellucci, along with Novak Djokovic, Rafael Nadal, Roger Federer and not many other active players, has a winning record against Murray.

The 27-year-old won his only previous meeting with Murray, prevailing 6-4 6-2 in the last 16 of the Madrid Masters in 2011.

And we are back in the room.

Good early morning to you and welcome to coverage of Andy Murray's third-round meeting with Thomaz Bellucci at the US Open.

Murray has made heavy weather of his progress through the draw so far, offing Nick Kyrgios in four sets in the first round and then clambering back from two sets to love down against Adrian Mannarino in the second.

Early to bed this time Andy yeah?

Right then. That's it from me for today. Thanks for all your comments. 

Andy Murray is up later today, with a 02:00 BST start, so make sure you join Mike Henson for that one. 

Until then there's a break in the live text coverage, but you can continue listening to action from New York at the top of this page using the audio icon from around 19:00 BST. 

See you soon!

Jo Konta, speaking to Sky Sports:  "I've been here for about two weeks now and so I am just chuffed to still be here. I was trying to dicate to her, get her on her back foot, because she is most comfortable when dicatinh herself. 

"I'm happy I was able to take charge, and I'm happy that when I had to be scarppy and get balls back, I did that too.

"I didn't even know I was playing her but Petra Kvitova is a top five player I think. I'll have to have a talk to my coach but will be really looking forward to playing here again in front of so many people."

Jo Konta, speaking to Sky Sports: " Right now I am just getting used to not being out there trying to hit match points! 

"She may not have been feeling her best but she was still one of the best competitors, credit to her. 

"I'm happy I was able to stay as calm as I did. There was a lot of nerves but I enjoyed them. I enjoyed them and I enjoyed the situation."

Incredible stuff from Jo Konta. 

How far can she go? Today was her first appearance in the last 32 of a Grand Slam and she nailed it. Eventually.

She's enjoying her moment, smashing balls into the sparse but jubilant crowd. 

How many will be there for her next match? 

She's up against Petra Kvitova next the two-time Wimbledon champion will be a stern test indeed.  

Konta has done it! The sixth time is the charm! 

Petkovic looks for the far corner, she puts serious pace on the ball but it's long and wide. 

Now Konta can smile. She's through to the US Open last 16. Wow. 

The two players embrace at the net.

A fifth match point. There's a massive scream from Konta. This one. Now. Surely. Yes? 

Konta is way wide on her first serve, the second is slow and Petkovic latches on tight. The German hits one into the far corner and Konta can only find the net. 

How many more match points are we going to have?!

And the fourth one is wasted too! 

Konta hits long and we are back to deuce. The forehand side again - it looked like she held something back on that shot for sure.

Here we go then. Deep breath from Konta. She's been here before now. But not long enough ago?

It's edgy, her forehand slipping slightly to led Petkovic in, enough for a 30-30 share. 

Petkovic then hits wide when it looked easier not to. Here's a fourth match point...

You've just seen three match points slip through your fingers. How do you react? 

Konta deals with it admirably, she's really going for her shots. Petkovic seems to have found another level but Konta has the reply - a fantastic forehand winner from one corner to the other. 

But Petkovic grows again, surging into a 40-30 lead with a lovely drop shot before sealing the game with a forehand winner. 

Konta is still serving for the match...

Third time lucky for Konta? Nope. Petkovic is clinging on.

She looked to be starting to wilt again but buys herself a little more time and a break point with a testing drop shot that Konta can only send spinning on the reach. 

Petkovic then sees the game out but she still trails by three... Surely that's too much to ask?

This really is cat and mouse stuff now. The game edges up and away beyond seven minutes, both players retreat to the baseline. 

Konta hits a massive forehand, it hits the top of the net.. and... bounces on Petkovic's side. 

A second match point. But it's saved again! A vicious return from Petkovic is sent spinning by a Konta slice.

Konta sets herself up for match point with a strong serve, Petkovic responds with a defiant deep return on the next, back to deuce. 

Brilliant from both players at the net, Konta with a tasty drop-shot, Petkovic is so quick to pounce to force the break. But again her forehand is disappointing. Back to level terms. 

Again.

Who would have thought this second set would be so one-sided? Especially after the start of that first-set tie-break. 

How will Konta cope with this? Well surely she can't let her lead slip now... Can she? Petkovic zooms into a three-break point lead. 

Konta claws back one, and then another as Petkovic hits long...
