Mirra Andreeva reaches first Grand Slam final at Roland Garros, ends Marta Kostyuk's clay win streak

For the first time in her budding career, Mirra Andreeva will play for a Grand Slam title.

The 19-year-old became the first player to defeat Marta Kostyuk on clay this season, racing to a 6-1, 6-3 victory in Thursday’s opening Roland Garros women’s semifinal.

“The conditions were very tough today. I couldn’t understand which direction the wind was going,” Andreeva told Marion Bartoli on court. “I’m just happy I was able to stay focused. I told myself to accept everything that happens today on the court. It was a little bit unpredictable.”

Andreeva had lost her previous two meetings with Kostyuk, including May’s Mutua Madrid Open final. With the experience of a 2024 semifinal at this event under her belt, the No. 8 seed raced to a 4-0 lead.

Maintaining her composure throughout the encounter, a rock-solid Andreeva executed a flawless game plan in the windy conditions. Kostyuk struggled to produce the tennis that led her to this stage of a major for the first time, venting her frustrations from time to time.

Andreeva’s lone blip came at 4-2 in the second set, when she was broken at love on the back of a double fault and errant forehand. But she immediately regrouped, mixing up pace to generate a re-break—and subsequently served out the contest on her first time of asking.

Kostyuk finished with a –19 differential in winner to unforced errors to see her 17-match win streak on the surface ended.

Contesting her 13th major main draw, Andreeva is the youngest woman to reach a Grand Slam final in four years—when an 18-year-old Coco Gauff finished as the French Open runner-up to Iga Swiatek. The Russian owns a tour leading 21 clay-court wins and 35 match wins overall, as she bids to become the WTA's third youngest first-time major winner this century behind Maria Sharapova and Emma Raducanu.

Andreeva’s frequent doubles partner Diana Shnaider and qualifier Maja Chwalińska were due to meet in the second final-four matchup.
