The crowd will get behind Anisimova here. They will not want this match to end just yet.

Anisimova does what she needs to do and takes the hold to force Sabalenka to serve it out for the title.

That might sound easy enough but Sabalenka has been broken three times in this match. It might not be that simple.

There is impressive ball-striking from both players but then Anisimova struggles to keep up with things.

Sabalenka tried to attempt a slice shot in that last game from a defensive position - she has not used that much today.

Anisimova is running out of time.

It's now or never for Anisimova. It looks like she's racing to a hold as she gets out to 40-0 but all of a sudden Sabalenka takes it up a gear to get to 40-30.

I would like to see Sabalenka have to earn this, not Anisimova just give it away.

It pays off as she takes the hold to 15.

That will hurt Anisimova. You have to admire Sabalenka however. She has unbelievable sense of character. She makes it a show and wears her heart on her sleeve.

This crowd are ramping up.

Nothing like a hold of serve for their player to get the Ashe crowd fired up.

Oh, and some megastars appearing on the jumbotron.

Stephen Colbert - the recently-axed late-night chat show host - and Mad Men star Jon Hamm bring up the loudest cheers of the evening.

That gets everyone going and the energised excitement, ironically, helps carry a calmer Anisimova to the break.

This has very much been a battle of the minds.

You can just see the ups and downs that both players are going through. Battling their emotions before and after every single point.

The ebbs and flows of a Grand Slam final, eh?

There is a little bit more sense of urgency from Anisimova. She is looking more energised and she is looking hungrier.

Nerves are just starting to get to Sabalenka here - she is teetering a little bit. She is allowing the American back into things.

And just like that Anisimova is back in this.

A sumptuous backhand seals the break-back at the first opportunity.

The crowd are willing Anisimova to get back into this and it works as she wins the first point on the Sabalenka serve after a brilliant rally.

A double fault from the top seed hands over three break points.

Anisimova is showing everyone with her body language that she is not happy about how this match is unfolding.

Sabalenka is looking comfortable and has time on the ball. She feels like she has got this and will keep her foot on the pedal.

A crucial game to keep Anisimova in touch.

A much-needed hold to15 on the board for Anisimova.

The hope that she can get back into this remains alive as long as she can stay somewhat in touch on the scoreboard.

The next few minutes could be the match. Anisimova needs to reel things otherwise this game is gone from her.

You have to be more direct as a coach and say something to try and change the player's mindset.

This match is being lost in between points.

Anisimova seems to be losing confidence and rapidly.

She looks despondent after a couple of massive Sabalenka serves that she's unable to do anything about secure the hold for the Belarusian.

This is smart tennis from Sabalenka. She can play big tennis but is also using the variations she has to draw mistakes from Anisimova.

Anisimova needs to let everything out to somebody. This is where the coach needs to interject and see if you can snap the player out of it.

Sabalenka threads the backhand drive down the line and takes the break of serve at the second opportunity.

The top seed seems to be racing away with this at the moment.

Anisimova needs to refocus.
