Mirra Andreeva reaches maiden Grand Slam final with dominant win over Marta Kostyuk at French Open 2026

Teenage sensation Mirra Andreeva delivered a composed and commanding display to reach her maiden Grand Slam final at the French Open 2026. The 19-year-old defeated 15th seed Marta Kostyuk 6-1, 6-3 in the semifinals on Court Philippe-Chatrier, becoming the youngest woman to reach a major final since Coco Gauff at Roland Garros in 2022.

Andreeva, who tops the WTA Tour with 35 wins this season, will now wait for the winner of the other semifinal between Diana Shnaider and Maja Chwalinska. The victory also ended Kostyuk’s 17-match winning streak on clay and marked Andreeva’s first win over the Ukrainian after losing their previous two meetings without taking a set.

Two years after losing to Jasmine Paolini in the Roland Garros semifinals, Mirra Andreeva returned to the same stage and produced a performance full of maturity. She became the fifth-youngest woman to reach the French Open final in the last 30 years. The Russian teenager showed clear growth, dictating rallies from the baseline and moving Marta Kostyuk around the court with precision and power throughout the match.

Mirra Andreeva reflects on windy battle

After the match, Andreeva admitted the windy conditions made the contest unpredictable but praised her own ability to stay focused.

“Yeah, first of all, the conditions were very tough today. It was windy. I couldn't understand which direction the wind was going, and it was very tough,” Andreeva said after the match.

“But I'm happy that I was able to stay focused. I told myself to accept everything that happened on the court today because it was one of those days when I felt like everything could happen. It was a little bit unpredictable.

“I just told myself that no matter what happens, I'm going to give my best. If she ends up winning, then she's going to have to really work for it and fight for it,” Andreeva added.

Mirra Andreeva will now prepare for her first Grand Slam final, where she will face either Shnaider or Chwalinska.
