Ouch. Boisson begins her second service game with a double fault then Gauff overpowers her in the rallies and the American has two break points for a double break.

A long loopy forehand drops the wrong side of the paint for Boisson and that's the hold for Gauff.

This is going to be a tough afternoon for the Frenchwoman.

Can she get herself on the board?

I've been impressed with the mental fortitude of Lois Boisson. Nothing fazes her.

She might look down every once in a while or she might shake her head, but she just gets up there and delivers.

Settle in, folks.

Not much in the way of short points here with the majority resulting in a rally.

Gauff unleashes the power on her backhand then knocks down Boisson's overhead smash for game point.

Strong start from Gauff as she breaks Boisson in the first game.

The American will be delighted with that and even more delighted with the crowd's reaction. Quiet.

Lois Boisson's tournament is hard to believe.

The only run I can compare it to is Emma Raducanu's when she won the US Open.

I think they were at similar rankings, but this is even more dramatic because of the players she has beaten. She saw off Jessica Pegula and Mirra Andreeva back-to-back.

If she beats Coco Gauff, I can't even imagine the celebrations and the noise in this arena!

Gauff has a break point already here after a really entertaining game.

Boisson will probably need to feel her way into this game but Gauff will not allow that.

Oh what a shot that is.

I was about to say there must be a few nerves for Boisson but based on that shot I'm not so sure.

Gauff does well to return a really good serve anyway but Boisson comes into the net and it's a delightful touch to just float it over the net.

Sumptuous.

Off we go then. A French Open final against Aryna Sabalenka awaits.

Boisson to serve first.

World number 361 Lois Boisson says she is not satisfied with defying the odds to reach the semi-finals of the French Open and wants to fulfil a childhood "dream" by winning her home Grand Slam.

Boisson, who entered the Roland Garros draw as a wildcard, ensured her fairytale run would continue with a 7-6 (8-6) 6-3 triumph over sixth seed Mirra Andreeva.

The Frenchwoman has now beaten three seeded players en route to the last four, where she will meet world number two Coco Gauff.

"I think every kid who plays tennis has the dream to win a Grand Slam," said Boisson, 22. "I will go for the dream, because my dream is to win it, not to be in the semi-final. So I will try to do my best for it."

Boisson, appearing in her first Grand Slam main draw, was set to be a wildcard at Roland Garros last year but had to pull out after tearing an anterior cruciate ligament in her knee just a week before the French Open was due to begin.

But 12 months on, she becomes the first player in the Open era to reach the women's singles semi-finals at the French Open as a wildcard, and the first French semi-finalist since Marion Bartoli in 2011.

"I don't think it's a miracle," she said. "I've had a little bit of luck, but I think it's just the hard work that I put in since I started playing tennis and also last year with my rehab and everything. It's the result of hard work. Nothing else."

Coco Gauff is hunting a second Grand Slam title after winning the US Open two years ago.

And make no mistake she's here to upset the party.

But at 21 years old, she's still only young herself and we've seen experienced players struggle in the Chatrier cauldron.

Should be a cracker.

Lois Boisson turned professional in 2021 and was playing on the third rung of the women's tennis tour last year.

She was building momentum in the run-up to the 2024 French Open, winning three ITF Circuit titles and a WTA Challenger event in May to earn a wildcard for her home Grand Slam.

But an ACL injury to her left knee shattered Boisson's dream of competing at Roland Garros and she was unable to bring herself to watch the tournament play out.

Boisson took every step to speed up her recovery, utilising neurovisual training, which included sight tests, buzzer reaction tests and using virtual reality headsets to keep her reactions sharp.

Those efforts paid off when she returned to action in February and earned a win over Briton Harriet Dart when making her return to the WTA Tour at the Rouen Open two months ago.

That match hit the headlines after Dart was forced to apologise to Boisson after asking the umpire to tell her opponent to put on deodorant.

But Boisson saw the funny side of the issue and later posted an edited photo of her holding some deodorant and telling toiletries company Dove they they "need a collab".

What a story this has been.

Frenchwoman Lois Boisson stunned third seed Jessica Pegula in the fourth round before sending the French crowds into a frenzy when she beat 18-year-old star Mirra Andreeva on Wednesday.

Both of those top-10 players struggled with the crowd, who were of course fully behind their home player Boisson.

Will second seed Coco Gauff be able to deal with that today? It'll be even more intense with the roof on.

You'd expect Court Philippe Chatrier will be jam-packed for Lois Boisson, right?

Maybe not. The Roland Garros crowd is not known for its stamina and, based on historical evidence, many have disappeared for a breather after the first semi-final.

It will be interesting to see how quickly - or slowly - the 15,000-seater stadium fills up again.

The several thousand who have not moved give a loud and very noisy welcome to Boisson.

Then they start cheering each of her returns during the warm-up...

So, Aryna Sabalenka is into the French Open final.

Who will be joining her?

Will it be the fairy-tale story? Or the young superstar?

The players are out to warm up and already the crowd are getting whipped up. A muted round of applause for Coco Gauff while Lois Boisson received a huge reception as expected.

It's an enemies to friends arc in the men's wheelchair events today, as Gordon Reid and Alfie Hewett team up for their doubles semi-final.

Earlier, the two Brits met in a singles quarter-final, with Hewitt triumphing 6-2 6-4.

The pair are now on the same side of the court, the top seeds in the men's doubles last four against Casey Ratzlaff of the USA and Japan's Takuya Miki.

And they needed a little over half an hour to take the first in this three-set match, breaking their opponents four times in doing so.

Aryna Sabalenka has become the player with the most women’s singles Grand Slam finals this decade, surpassing Iga Swiatek by reaching her sixth.

The Belarusian is also the first women's player to reach the final in three consecutive Grand Slam singles events since Serena Williams in 2016.

She has delivered Swiatek's first defeat at Roland Garros since 9 June 2021 - 26 matches and 1457 days ago, almost four years to the day.

Speaking about whether she will watch the semi-final between Lois Boisson and Coco Gauff, she said: "I will let my team watch it today, and tomorrow we are going to watch it together. It depends who's going to win the match.

"It is another great semi-final so enjoy it guys. I'm pretty sure you are going to be cheering one person on like crazy and I'm not sure if I really want her [Lois Boisson] to win!"

World number one Aryna Sabalenka speaking on court after reaching her first French Open final: "Honestly it feels incredible, but I also understand the job is not done yet.

"I'm just thrilled with my performance today and with the win. The atmosphere in the stadium, thank you so much. It makes us feel amazing, so thank you.

"Iga [Swiatek] is the toughest opponent, especially on the clay and at Roland Garros. I'm proud that I was able to get this win. It was a tough match, it was tricky, but I managed it somehow and I'm super proud right now.

"I'm glad that I found my serve [in the third set]. It was a bit easier with the serve. What can I say, 6-0 - it couldn't be much more perfect than that!"
