All of a sudden she is finding her best tennis. She looks very at ease, she isn't tense and she is going for it.
She said ahead of this match that she wants to walk off court leaving everything out here, and she is doing exactly that.

Madison Keys spoke a lot in the lead-up to this final about her previous tough Slam experiences, including her straight-set loss to Sloane Stephens in her only previous major final eight years ago.
Of course, facing Aryna Sabalenka undoubtedly brought back memories of her US Open semi-final loss from such a dominant position, especially after she win the first set again here.
But she looks a different player today. The American is still standing firm as Sabalenka searches for that fatal blow, holding from 40-30 to move within one game of victory.

If Sabalenka continues to try and get that service percentage up, it is going to get more and more tricky for Keys here...
I think, as we start to get into the heart of this match, it is going to get even more edgy. I reckon the crowd can sense it as well.

This crowd is waiting to see some really fabulous tennis between these two players.
It would be nice to get them both playing well at the same time because they seem to be toing and froing, and it is quite an awkward watch.

It is ominous for Madison Keys in many ways, isn't it?
Although, we have to remember how she equipped herself in the third set against Iga Swiatek before winning in the third set tie-break.
Aryna Sabalenka is serving so much better in the second set, which obviously makes a huge difference for her.
She did lose the first set to Elena Rybakina when she won the Australian Open two years ago though, so she does have experience of coming from behind...

Aryna Sabalenka double faults on her second set point.
