Incredible stuff. Maja Chwalinska is first out of her chair here.

BBC Sport tennis news reporter at Roland Garros
A guy with a Polish flag in front of the media seats cannot contain his excitement as Chwalinska breaks.
He's shrieking, covering his face with his hands and bouncing on the spot.
Virtually every other Polish fan here is doing the same.
It is going to erupt if she serves out...

The qualifier will now serve for a place in the French Open final

Image source, Getty ImagesIt has been a high level match. It has been so intriguing. That variation again from Maja Chwalinska...She grows with confidence.
Shnaider 6-7 (4-7) 4-4 Chwalinska*
Here we go! A HUGE chance for Maja Chwalinska.
She brings up two break points after drawing Diana Shnaider in with a deft drop shot and then volleying into the empty court left behind.

Diana Shnaider leaning forward. If you're not feeling 100%, then this is not the opponent you want at the other end of the court. You are not going to get anything for free. It was a big hold of serve from Maja Chwalinska.

Image source, Getty ImagesDiana Shnaider looks up at the sky and mutters to herself after looping a forehand long. She looks exhausted.
But it doesn't seem like Maja Chwalinska is feeling her best either, with another double fault.
She sees the hold through, though, as Shnaider finds the fence.

It doesn't look like Diana Shnaider is struggling with her movement, but Maja Chwalinska opens up a 30-0 lead with a backhand winner down the line.

This is one of the most painful physio treatments. It is absolutely awful to release those hip flexors off.

This match is taking everything out of these players.

One hour and 51 minutes has been played. I thought this could be a three-hour match, but we might go way past that!
Shnaider 6-7 (4-7) 4-3 Chwalinska*
On we go. Both players are looking fairly comfortable on serve at the minute and Diana Shnaider nudges ahead.
But the trainer is out on court. It looks like the Russian 25th seed has an issue with her lower back.

On Maja Chwalinska being this good mover, she is not afraid to step up and hit it when the ball is short.
Diana Shnaider looks like she is starting to fight with her emotions a little bit. I don't think there is tears, but she is definitely looking flustered.

I think Maja Chwalinska makes you beat yourself. She puts an incredible amount of balls back into play and her movement is great. Ultimately, she knocks you off rhythm.
Shnaider 6-7 (4-7) 3-2 Chwalinska*
Hmm. Maybe not. Maja Chwalinska has defended so well in this match, but she doesn't bother sprinting for that ball.
And the drop shot-lob combo doesn't pay off this time. A bit of fatigue creeping in perhaps?
A straightforward hold for Diana Shnaider.
