One month on from their Madrid Open final meeting, Marta Kostyuk takes on Mirra Andreeva for a place in the 2026 French Open final.
Both players arrive at the last four in extraordinary form, with Kostyuk riding a 17‑match clay‑court winning streak and Andreeva racking up a WTA-leading 34 wins in 2026
Kostyuk clinched her place in the semi-finals with a thrilling three-set win over compatriot Elina Svitolina, thus becoming the first Ukrainian woman ever to reach this stage at the French Open.
After making short work of four-time champion Iga Swiatek in the fourth round, Kostyuk was forced to regroup against the 31-year-old before sealing victory by taking the final 14 points of the match in a blur of winners, smashes and fearless aggression.
Andreeva, meanwhile, dismantled Sorana Cirstea 6‑0, 6‑3 in just 56 minutes, producing one of the most dominant quarter‑final displays of the modern era.
Under the closed roof of Court Philippe Chatrier, the 19-year-old lost only nine points in the opening set, converted all six break points, and finished with 18 winners to Cirstea’s four.
She will bid to back that performance up in her second appearance in the last four at Roland Garros and must learn from the bitter experience of her defeat to Jasmine Paolini at this stage two years ago.
It is also only four weeks since she was reduced to tears after losing to Kostyuk 6-3, 7-5 in Madrid, her second defeat to the Ukrainian this year.

Marta Kostyuk v Mirra Andreeva Prediction
Best Bet: Over 22.5 Games @ 5/6
Their Madrid final featured long rallies, tight games and extended momentum swings despite the straight‑sets scoreline.
Kostyuk ran out a 7-5, 6-3 winner, but there was not much between them bar a few key points with the Ukrainian clinching all four of her break points while Andreeva wasted as many, converting only two.
This rematch feels too close, too intense and too tactically rich to be over quickly.
Andreeva has dropped just one set all tournament but has been pushed to long, physical exchanges in every match.
Kostyuk’s aggressive, first‑strike tennis forces short points - but her streak has also included multiple three‑set battles.
Both players have elite return games, meaning breaks of serve are likely to be traded.
Andreeva’s defensive anticipation and Kostyuk’s explosive baseline aggression should produce a match full of tactical shifts.
But the added nerves of playing in a Grand Slam semi means that a three‑setter feels like it could be on the cards.
Alternative Bet: Kostyuk to win 2‑1 @ 11/4
Kostyuk’s clay‑court level this season has been extraordinary and she now enters this clash as the favourite.
But she showed some vulnerability against Svitolina, dropping the second set in a match that evened out after her blistering 3-0 start.
Andreeva’s 20 wins on the surface this year suggest she will push the Ukrainian to the limit, but her two losses to Kostyuk suggest there is a problem to overcome.
The teenager has struggled to impose her game on two of the best defensive players in the women’s game - Kostyuk and Gauff - and is now 0-7 against the duo.
She made some key errors at the net in their last meeting when Kostyuk attempted drop shots to throw her out of rhythm and will need to be wary of that tactic on Thursday.
The Ukrainian will also hope that her greater power and surging confidence pull her through in the big moments again and potentially tilt a deciding set her way.
Five of her 17 clay-court wins this year have featured three sets and this one bears all the hallmarks of another.

Kostyuk holds the 2-0 head-to-head edge over Andreeva and it seems more than just psychological as her ability to extend rallies and force the Russian into the net, where she is not so comfortable, has determined key points.
The Ukrainian’s serve has been up and down throughout the tournament with Kostyuk averaging almost five double faults per match in Paris, so she could easily top 4.5 in a potential three-set contest.
But her ability to break serve is almost unmatched and, after this duo traded six breaks in Madrid a month ago, there is a good chance that the added nerves play a part in pushing the total breaks above eight here.
