The women's semi-finals are the focus for Day 12 of the 2025 French Open, with two mouthwatering ties on Court Philippe-Chatrier.

The most eye-catching is at the top of the draw, where Aryna Sabalenka and Iga Swiatek lock horns for the 13th time in their careers.

Swiatek, the four-time winner at Roland-Garros, is up 8-4 in the pair's head-to-head, but they have never faced each other at the French Open until now.

Sabalenka, the world No. 1 and three-time major champion, has not dropped a set in Paris and is in hot form as she prepares to battle the 'Queen of Clay'.

On the other side of the draw, world No. 2 Coco Gauff will take on the home favourite Lois Boisson, who knocked out Mirra Andreeva, the sixth seed, in the quarters to reach the last four in her first Roland-Garros.

As well as all the live coverage from around Roland-Garros, there will be expert analysis from on-site and in the studio.

When does Aryna Sabalenka play Iga Swiatek?

Sabalenka is perfect in her run to the last four in this year's competition.

She is looking to reach the final for the first time at Roland-Garros, and she is in excellent form having swept Olympic champion Qinwen Zheng aside in the quarter-finals.

As for Swiatek, there were plenty of question marks over the Pole's consistency coming into the French Open, with her clay-court swing not bearing anywhere near the amount of fruit that it has done previously.

Swiatek is chasing a first title since winning a fourth French Open last year, and she is out to prove a point after early exits in Madrid and Rome in the lead-up.

This hotly anticipated clash is slated to be second on Court Philippe-Chatrier after the mixed doubles final.

When does Coco Gauff play Lois Boisson?

Gauff, one of the stars of the women's game, faces off against Boisson, who stunned Andreeva to follow up her surprise victory over Jessica Pegula, in the other semi-final on Chatrier, and they are up after Sabalenka's clash with Swiatek.

The American had to battle inconsistency and plenty of unforced errors against Australian Open champion Madison Keys, but she roared back in the third set to take the match 6-7(8) 6-4 6-1 on Wednesday.

Meanwhile, Boisson, the world No. 361, produced a spectacular victory over Andreeva in straight sets, coming back from being down in both sets to oust the sixth seed and earn her meeting with Gauff.
