Talk about a dream run.

A clip has emerged on Instagram of world number 361 Lois Boisson hitting with none other than men's world number one Jannik Sinner.

What a week.

It's been plain sailing for Mirra Andreeva so far this tournament.

She only dropped four games on her way to the fourth round, where she faced her toughest match of the campaign against Daria Kasatkina, losing a set for the first time.

But she rallied from 3-5 in the second set to win and book her quarter-final place.

For Lois Boisson, it's been a dream run which has included toppling third seed Jessica Pegula.

The 22-year-old made her Tour-level main draw debut on the home clay courts of Rouen a few weeks ago and only got so far as the second round.

Now, she is celebrating becoming the lowest-ranked quarter-finalist at Roland Garros in four decades.

It's easy to forget that Mirra Andreeva is just 18 years old as she already seems to be a pretty regular feature in the latter stages of the big tournaments.

The teenager has title wins in Dubai and at Indian Wells under her belt.

She'll be hoping to replicate her run to the semis at Roland Garros last year, her best result at a Grand Slam.

World number 361 Lois Boisson registered the biggest shock of this year's French Open when she pulled off a stunning fourth-round victory against third seed Jessica Pegula.

The French player was given a wildcard into the main draw after tearing an anterior cruciate ligament in her knee last year.

Boisson is making her debut in the main draw of a Grand Slam and had never played an opponent ranked in the world's top 50 before this week.

Things looked very different for Boisson 12 months ago.

After a successful series of performances on the third rung of the women's tennis tour, Boisson was given a wildcard for her home Grand Slam.

However, a week before the clay-court tournament began, Boisson tore the ACL in her left knee. She was unable to bring herself to watch last year's French Open and subsequently missed nine months of the season.

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

She made her WTA Tour return at April's Rouen Open against Harriet Dart, where the Briton apologised for asking the umpire to tell her opponent to put on deodorant.

Boisson later made light of the issue, posting an edited photo of her holding some deodorant and telling toiletries company Dove that they "apparently need a collab".

Able to use the wildcard that injury denied her last year, Boisson beat 24th seed Elise Mertens in her opening match and overcame a second-set 'bagel' to beat compatriot Elsa Jacquemot in the third round.

Lois Boisson and Mirra Andreeva head out on to court for the warm-ups.

What a moment for Frenchwoman Boisson, stepping out onto Chatrier in front of a home crowd for a Grand Slam quarter-final.

Speaking about how much the conditions change when the roof is closed on Court Philippe-Chatrier, Coco Gauff said: "My last match was warmer so I was playing with a lower tension today. Then I went down 4-1 and I changed it and I went 5-4, so I don't know if it had anything to do with that. It's difficult to kind of find the tension and how you want to play.

"Honestly I thought the ball would play slower. It did in some moments but I felt it was kind of quick too. But I was playing Madison [Keys], so I don't know if that was the reason why the ball felt so fast today."

On what the French Open means to her: "It means a lot, especially after getting through this tough match today. It wasn't an easy match and I'm very happy to get through it. I'm just very excited to be back in the semi-finals here again. I have a lot more work to do but I'm going to savour this one today. I'll be ready for tomorrow's match."

So, our semi-finals line-up is almost complete.

Will it be teenager Mirra Andreeva or wildcard Lois Boisson completing the quartet?

• Iga Swiatek [5] v Aryna Sabalenka [1]
• Coco Gauff [2] v ???

World number two Coco Gauff speaking on Court Philippe-Chatrier after sealing her semi-final spot: "I changed something at 4-1 in that first set and after that I had chances to win the set. Madison [Keys] was playing well so I was just trying to get the ball deep and be aggressive, but it's tough because she was hitting the ball so fast and so low. I was just trying to fight for every point.

"She is obviously a very great player and her forehand is probably one of the best, if not the best, on tour. I was just trying my best to get it on the other side of the court, but she has a great inside-out and inside-in forehand.

"Honestly I knew that I just had to be able to run today. As soon as the ball came short, I knew I had to punish her for it."

That is Coco Gauff's third win in six meetings with fellow American Madison Keys but the first time she has claimed victory since 2023.

Gauff won the doubles title at the French Open last year but is yet to get her hands on the singles title.

Could 2025 be Gauff's year?

Wow, what a match from Coco Gauff!

It wasn't pretty in the beginning but she found her game over the course of this match.

One thing she never ever lacks is competition. She always competes and that won her this match today.

Coco Gauff has just found enough in the tank in this final set to take control and a forehand winner down the line hands her three match points.

Madison Keys puts a backhand into the net and then stretches out her shoulders.

Keys has a mountain to climb to stay in the hunt for a second career Grand Slam title.

A couple of breaks up, Coco Gauff is racing towards the semi-finals of the French Open for the third time in her career.

Gauff follows her backhand to the net and slices a winner to move within a point of holding.

Madison Keys can't return Gauff's serve.

It feels like Coco Gauff is the more solid player in the baseline rallies right now. That is great news for her after being under pressure for such a long time from Madison Keys' forehand side in particular.

On the other hand, Keys' backhand has gone back to the locker room. She is particularly struggling with the off-pace shots from Gauff that have been hit with a bit more rotation.

The confidence is flowing for Coco Gauff as she steps forward to smash through with her forehand and the return is into the net.

Another opportunity to break and Gauff gets it this time.

Coco Gauff is caught on her heels and Madison Keys fights back to deuce.

A huge service game for Madison Keys to come. Falling two breaks down in the third and final set is not where you want to be.

A fine cross-court strike from Coco Gauff catches Keys by surprise and it's returned into the net.

Another hold to love for Coco Gauff.

The 21-year-old doesn't look like dropping another point on serve - in stark contrast to how she was performing in the opening two sets.
