Oh no. A double fault hands Sabalenka the double mini-break and she could quite easily run away with this now given her record in tie-breaks.

After holding nerve and holding serve, Sabalenka forces the tie-break.
This is where she shines. Sabalenka has won her past 18 deciders...

Sabalenka did well to hit that ball from the baseline - it was pure instinct from her and almost like a volley.
Her second serve is looking a little bit shaky.
Sabalenka is trying to stay calm and has gone into a floating mode. She is trying to compose herself.
Sabalenka 6-3 6-6 Anisimova
A couple of really good shots and a big serve from Sabalenka wrap up the hold and we're heading to a tie-break.

Sabalenka found the febrile nature of the New York crowd difficult to handle in the 2023 final against Coco Gauff, I seem to remember.
Then again, she did beat Jessie Pegula here last year.
Fascinating to see which way this one goes for the Belarusian...
*Sabalenka 6-3 5-6 Anisimova
Sabalenka had a wry smile up at her coaching box when she missed that overhead smash to hand Anisimova a break point as if to say 'this isn't over'.
And it isn't. The defending champion has gone from serving for the championship to serving to force a tie-break.

Anisimova is getting linear strokes into the corners and is setting panic in at the other end of the court.
Sabalenka is starting to doubt herself.
Anisimova could not have played that any better and she is strolling to the other end - she looks so in control.
*Sabalenka 6-3 5-6 Anisimova
A double fault from the American is followed by an overcooked Sabalenka return and there's the hold for Anisimova.
The 24-year-old is suddenly on top in this set.
Sabalenka can not believe what has happened here. She was two points from winning the title.
Sabalenka 6-3 5-5 Anisimova*
Now we're seeing some of the Anisimova shots that we have become accustomed to over the past couple of weeks.
A sublime forehand winner then a pummelled backhand get her out to game point.

It was never going to be easy...
Sabalenka doesn't know where to look as she fails to see the match out.
Anisimova is suddenly playing lights out again.
The noise is incredible as the home fans cheer their girl on.

A totally different match is on our hands now.
You have to feel for Sabalenka - she cannot believe what has just happened. She should have put that smash shot away easily.
Anisimova is in for a fight.
Sabalenka 6-3 5-5 Anisimova*
Anisimova hits what could be a winning shot but somehow Sabalenka gets it back in play but then she fires down another and this time the top seed can't get it back over the net and that seals the break back!
The tension. Wow.
*Sabalenka 6-3 5-4 Anisimova
No way! Sabalenka misses the overhead smash and hands Anisimova a break point!
Nerves creeping in for the top seed?

Sabalenka will not be happy about having to serve for the match here - her heart will be pounding.
A perfect first point from her however.
*Sabalenka 6-3 5-4 Anisimova
A loose forehand from Anisimova after a powerful second serve from Sabalenka and the Belarusian lets out a huge roar.
As we've seen her do so many times, she will try to cheer herself over the line. 30-30.
*Sabalenka 6-3 5-4 Anisimova
Here we go! Anisimova moves to 0-30 on the Sabalenka serve.
