Pegula will sit down trailing at the break, but she will still believe.

Pegula responds to that tricky game where she missed three break points by holding to love.
She's saying 'hello, I'm still here'.

Sabalenka is two games away from the final.
But Pegula is two games away from drawing level in this set.
Up for grabs.

Sabalenka saves break point again but an ambitious second serve at game point results in a double fault to take us back to deuce.
A smash volley hands her a second bite of the cherry before she takes the hold with a big serve.
Impressive stuff from the top seed.

Great quality on display this evening. You have to admire Sabalenka's attitude in the most pressurised situation.
*Sabalenka 4-6 6-3 3-2 Pegula
What?! I thought that was out! Sabalenka's backhand paints the line and takes us to deuce but she just overcooks it on the next point and Pegula will have a third crack at break point.

What a point to save the first break point. It's cat and mouse tennis with both players running each other ragged but Sabalenka's smash volley has the last word.

Pegula is left standing and staring at Sabalenka's passing shot as the screen shows it kissed the line.
But a couple of points later it's the Belarusian standing with her cheeks puffed out as she misses the forehand for 15-30.
Some nifty net play then brings up break back points for the American.

Pegula just needs to hang in there with patience, keep extending the rallies as long as she can and wait for the errors to come.
*Sabalenka 4-6 6-3 3-2 Pegula
Pegula keeps her cool to take a confident hold to love and remain in touching distance.

I'm not sure 'calm' is a word often associated with Sabalenka on court but she is certainly more in control.
Pegula gets lucky with a net cord that dribbles over in her favour but a couple of big serves put the game back in the Belarusian's control and she moves to take the hold.

Sabalenka has definitely calmed down after that first set.
*Sabalenka 4-6 6-3 2-1 Pegula
Pegula needed that.
Her first serve is still somewhat lacking but she takes the hold to love and gets herself on the board, reminding Sabalenka she's not going away in this deciding set.

How incredible to start so fast when it's been such an edgy match. Sabalenka finding an extra gear here.

Sabalenka looks like she means business now.
She takes the hold to love and consolidates that break in less than two minutes.
*Sabalenka 4-6 6-3 1-0 Pegula
Well that was rapid.
Sabalenka needs just five minutes to break in the opening game of this deciding set. A perfect start.

Right, which way is this going to go now, folks?
Will it be a third major final for Sabalenka this year or a second career major final for Pegula?

Sabalenka did well to get off to a fast start, but it started to fluctuate again. Some of her play is jaw-dropping the way that it often is, but there's also errors. I'm sure she feels she should have closed down that set easier than she did.

Sabalenka gets it all wrong at the net as Pegula sends over the drop shot and that wipes out the first set point.
But Sabalenka lets out a huge roar as a big serve gets the job done at the second opportunity.
We're all square in this semi-final.
