The world No. 1 was two points from victory before losing 12 of the last 13 games, in the latest shock of a chaotic Roland Garros.

Aryna Sabalenka had one foot in the semi-finals. Then the wind picked up, the errors piled in, and the world No. 1's French Open came crashing down.

Diana Shnaider, the No. 25 seed, fought back from a set and two breaks down to stun Sabalenka 3-6, 7-5, 6-0 on Court Philippe-Chatrier, booking the first Grand Slam semi-final of her career.

It was a collapse, plain and simple. Sabalenka served for the match at 5-4 in the second set and stood two points from the win.

From there she lost 12 of the final 13 games, was bageled in the decider, and finished with 57 unforced errors, more than double Shnaider's 26.

A Familiar Unravelling

The signs were everywhere. Sabalenka screamed at herself between points, and at one stage crouched and rested her head on her racket after another miss.

Shnaider, to her credit, kept her nerve, served well and let the mistakes come. Not every player can hold their level long enough to take advantage when Sabalenka wobbles, but the Russian did exactly that.

The reaction afterwards was raw. A stunned Sabalenka said she felt like she wanted to quit tennis right now, the words of a player who had let a golden chance slip rather than anything more serious.

She has reached the business end at Roland Garros in each of the past four years, losing last year's final to Coco Gauff, yet the one major she wants most still eludes her.

Shnaider's Breakthrough

For Shnaider, this is brand new territory. Her previous best at a major was the fourth round of the 2024 US Open, so a run to the last four is a genuine career breakthrough.

She has handled the pressure of the moment better than almost anyone left in the draw, and she arrives in the semi-finals with nothing to lose.

A Wide-Open Women's Draw

Sabalenka's exit blows the bracket apart. Her defeat guarantees two first-time Grand Slam finalists, and for the first time since 1977 there is no former major champion in either the men's or women's semi-finals.

Shnaider now meets qualifier Maja Chwalinska, the surprise package of the entire tournament, for a place in the final - and if you're looking to get involved, our guide on how to bet on tennis covers everything you need.

The other semi-final pairs No. 8 Mirra Andreeva with Marta Kostyuk. Andreeva is the highest seed left standing and will go in as the one to beat, but in a fortnight this unpredictable, nobody should be writing anyone off.
