If the first ten days of the 2026 French Open had already delivered more than their share of surprises, Day 11 proved that the tournament still had plenty of drama left. Under changeable conditions that featured blustery winds early and then rain forcing the roof closed on Philippe-Chatrier, the quarterfinals produced two major upsets on the women’s side and an all-Italian semifinal guarantee on the men’s side. The result is a final four that looks remarkably open and full of fresh faces.
The biggest shock came on Court Philippe-Chatrier when world No.1 Aryna Sabalenka suffered a dramatic collapse against Russia’s Diana Shnaider. The top seed had taken the first set and led 5-3 in the second, appearing firmly in control. Then everything unraveled. Shnaider won the next ten games in a row to complete a stunning 3-6, 7-5, 6-0 victory and reach her first Grand Slam semifinal.
“I guess mentally I got into a very deep, dark hole over there, and I just couldn’t get back mentally on track,” Sabalenka admitted afterward. “I don’t know when was the last time that happened to me, that I lost 10 games in a row.”
Shnaider, the world No.23, handled the difficult windy conditions far better as the match progressed. “Honestly, I’m speechless,” she told the crowd. “Obviously today there were tough conditions with the wind, and it was my first time playing Aryna – I was super nervous being in the quarterfinals for the first time. I feel like in the third set I finally found my rhythm and how to play.”

The world No.114 produced another impressive performance, defeating 22nd seed Anna Kalinskaya 7-6(3), 6-3. Chwalinska becomes only the second qualifier to reach the women’s semifinals in the Open era at Roland Garros.
“I honestly don’t know what is going on,” the 24-year-old said with a smile. “Every single match here is kind of crazy for me. I’m very grateful.” She added: “I’m happy it looks like I’m in control. I was definitely nervous, that’s normal because I care so, I’m stressed but I just focused on my game and my job and I’m happy I managed to do that.”

On the men’s side, Italy is assured of a finalist after two compelling quarterfinals. Tenth seed Flavio Cobolli came from a set and 3-1 down to defeat fourth seed Felix Auger-Aliassime 4-6, 6-4, 6-4, 6-4. The Italian showed some impressive fighting spirit, particularly after the difficult windy opening set.
“I think we played two different matches today,” Cobolli said. “The first set was incredibly windy, and it was really tough to play. I went to the toilet to think a bit to change something. I just said to myself to fight because I felt like this is the chance of my life. I have to give everything in my matches, and today I did it, so I’m really happy.”

Arnaldi advanced when Matteo Berrettini was forced to retire in their quarterfinal while trailing 7-5, 5-2 with a hip injury. Berrettini had started the match strongly but felt the problem worsening as the match went on.
“Even though it was obviously a big stage, I’m the last one that wants to retire,” Berrettini said. “I’m so tired of it. I just don’t want to do it, but sometimes you have to do it.”
Arnaldi, ranked 104th, becomes one of the lowest-ranked men to reach the French Open semifinals in recent decades. The 25-year-old has spent nearly 20 hours on court already this tournament but insisted he still has energy left. “It’s crazy to think I’m in the semifinals,” he said.

If someone had’ve suggested before the tournament began, that two Italians will face off in a semifinal, Jannik Sinner and Lorenzo Musetti jump to mind. But it’s Cobolli and Arnaldi that have outlasted. Their semifinal meeting will be a historic occasion for Italian tennis.
On the women’s side, the emergence of Shnaider and Chwalinska adds another layer of unpredictability. Chwalinska’s run from qualifier to semifinalist is one of the great underdog stories of the year, while Shnaider has shown she can rise to the occasion against the very best. Their semifinal will pit two very different styles against each other. No doubt both will be extremely nervous, so it will be interesting to see who handles it better.
The 2026 French Open has now reached a stage where almost every remaining player has a genuine chance to go all the way. With no Sinner, no Djokovic, and now no Sabalenka, the pressure and opportunity sit heavily on those still standing. It’s been a while since we had a brand new Major champion on both the men’s and women’s side. But we won’t have to wait long now.
