Russian teenager Mirra Andreeva reached her first Grand Slam final by defeating Marta Kostyuk of Ukraine 6-1, 6-3 in the French Open women's semifinal on Thursday, according to ESPN. The 19-year-old converted her first match point while serving for the match on Court Philippe-Chatrier.
How Andreeva dominated the match
Andreeva broke Kostyuk in the opening game and raced to a 4-0 lead within 16 minutes, according to Mint. She saved three break points at 0-40 in her opening service game before taking control with a series of forehand winners. The first set lasted only 33 minutes, with Andreeva winning 79 per cent of her first-serve points. In the second set, Kostyuk mounted a brief fightback and broke Andreeva at love while she was serving at 4-2, but the Russian immediately regrouped and served out the match on her first opportunity.
Why this win matters for Andreeva's career
At 19 years and 39 days, Andreeva is the youngest woman to reach a Grand Slam final since Coco Gauff at Roland Garros in 2022, according to Tennis Majors. This is her first Grand Slam final appearance after contesting 13 major main draws. The victory reversed her head-to-head record against Kostyuk from 0-2, with both previous defeats coming in 2026, including a loss in the Madrid Open final.
What ended Kostyuk's clay streak
Andreeva's victory ended Kostyuk's 17-match winning streak on clay, according to Tennis.com. The Ukrainian struggled to find her rhythm throughout the match, finishing with 34 unforced errors to only 15 winners—a deeply negative ratio that reflected her inability to settle into the contest. Her first-serve percentage held at just 51 per cent, and she was broken five times across two sets.
The other women's semifinal on Thursday featured left-handed players Diana Shnaider of Russia and Maja Chwalinska of Poland, with the winner to face Andreeva in the final.
