*Kostyuk 1-6 3-4 Andreeva
Image source, ReutersFor the first time in this match, Mirra Andreeva's level dips - and Marta Kostyuk is able to capitalise.
Three unforced errors from the Russian in that game.
The roof has closed, and there's a slightly different feel to this...
Kostyuk 1-6 2-4 Andreeva*
Hello!
The crowd are getting a bit excited now.
Marta Kostyuk shows a bit of patience - something she has lacked so far today - and comes out on top in a 26-shot rally which progressed from baseline exchanges to a slice showdown at the net for 0-30.
Double fault! Three break points...

Image source, Getty ImagesThere have certainly been better signs for Marta Kostyuk in this set, but she remains a clear second-best today.
The crowd are really appreciating her refusal to fold, however, and a couple more confidence-boosting winners take her to safety.
We saw one incredible comeback yesterday. She couldn't, could she...?

Rain is the air... so someone has pushed the button.
The roof is slowly sliding shut as Kostyuk serves in this sixth game of the second set.
Not sure if that will alter the conditions significantly in a short space of time - and therefore impact the course of this match.
*Kostyuk 1-6 1-4 Andreeva
The roof is being closed on Court Philippe Chatrier - but the match is continuing while it does so.
As every game has been for the Ukrainian, this is another mini-battle for Marta Kostyuk.
She recovers to 30-30 with a forehand winner, but Mirra Andreeva will have yet another break point.

This is where you try to key into the energy from the crowd.
There's some small signs for Marta Kostyuk, the rally could have gone either way, but it was savvy from Mirra Andreeva to move forward to the net.
*Kostyuk 1-6 1-4 Andreeva
Image source, ReutersA huge roar from Mirra Andreeva!
That is possibly in response to the crowd support for her opponent, but the 19-year-old Russian is also now just two games away from a first French Open final as she battles back from 15-30 to hold with three straight points.
It has been such an impressive display by the eighth seed.
Kostyuk 1-6 1-3 Andreeva*
Big cheers again for Marta Kostyuk as she fires in a forehand for the opening point on Mirra Andreeva's serve.
Will having the crowd so heavily behind her opponent begin to get to Andreeva?
The Russian misses a forehand for 15-30 and Kostyuk begins to sense an opening.

This was a key game for Marta Kostyuk to progress further in this tournament.
Let's hope that is the boost and impact of holding serve for Kostyuk.
The crowd wants to see a competitive match.

She will struggle to forgive herself if this one gets away from her.
Finally! A terrific drop shot earns cheers and applaud from the crowd as she at last holds to get on the board in the second set.
*Kostyuk 1-6 0-3 Andreeva
Marta Kostyuk has a word with herself at the back of the court after messing up a routine volley at the net on game point.
It doesn't have the desired effect, and she produces a double fault to bring Mirra Andreeva to deuce.
The frustration is really showing now as she nets on her third game point. She knows that this surely is game over if she doesn't get over the line here.

Marta Kostyuk is not helping herself. It is Kostyuk that is contributing to this healthy lead for Mirra Andreeva.

That really is another blow to Marta Kostyuk.
Kostyuk is being outplayed here.
*Kostyuk 1-6 0-3 Andreeva
Image source, Getty ImagesMirra Andreeva is just three games away from a place in the French Open final.
The Russian has been excellent, not least in defence, and stays in a final rally long enough to see Marta Kostyuk make a 22nd unforced error.

Marta Kostyuk is battling with herself, the opponent and maybe even the conditions.
Some quick breaths as Kostyuk stands there... I am sure her coaches are trying to get her to calm down.
Kostyuk 1-6 0-2 Andreeva*
Image source, Getty ImagesThat is so, so good.
Another stunner off the backhand from Mirra Andreeva gives her a perfect start in this set.
Marta Kostyuk is really up against it now.
*Kostyuk 1-6 0-1 Andreeva
A really important game here for Marta Kostyuk, no doubt about that.
But, after making a positive start to the second set on her opponent's serve, she misses a forehand. Break point.

That could be a huge game. Going back to the second game of set one, Mirra Andreeva had just broke serve. This might be another bonus for Mirra Andreeva to continue this momentum.
Image source, Getty ImagesMirra Andreeva may only be 19, but she is contesting her second semi-final at Roland Garros having also reached that stage in 2024.
If she goes on to win the title, she would become the third-youngest first-time Grand Slam champion this century, behind only Maria Sharapova and Emma Raducanu.
While Marta Kostyuk has an unrivalled unbeaten streak on clay, no player has amassed more wins on the surface this season - or indeed overall in 2026 - than Andreeva.
The Russian 19-year-old has 34 match wins this year, with 20 earned on clay.
Victory today would see her become the fourth-youngest woman to reach the French Open final in the last 30 years, after Martina Hingis, Kim Clijsters and Coco Gauff.
