The lucky loser who rewrites history against the Ukrainian machine

Anastasia Potapova should never have been there. Knocked out in qualifying by Sinja Kraus, brought back in as a lucky loser after Keys withdrew, she is now one match away from becoming the first lucky loser finalist at a WTA 1000 since the format was created in 1990. The run is vertiginous: Zhang, Ostapenko, Rybakina, Plíšková, four players of whom three are former world No. 1s or Grand Slam champions. Against Plíšková yesterday, trailing and with three match points to convert, she reeled off five games in a row to close out the third set. Her boyfriend told her between sets to shut up and work with her legs. She obeyed. On clay in 2026 she’s 9–2, her tiebreaks are at a 75% success rate on this surface this season, and she’s playing with the lightness of someone who has absolutely nothing to lose.

On the other side, Marta Kostyuk might be the in‑form player on the whole clay-court swing right now. Ten consecutive wins, a title in Rouen, and a run in Madrid without dropping a single set: Pegula 6–1 6–4, McNally 6–2 6–3, Noskova 7–6 6–0. That last score needs nuance: last night’s 6–0 in the second set is explained as much by Noskova’s physical collapse, exhausted after her 2:06 marathon against Gauff, as by an uptick in Kostyuk’s level. What remains indisputable: her return is the best of the tournament, with 82% of points won on Noskova’s second serve, a WTA 1000 record this season. The 2026 clay stats confirm this massive edge on return, 63.9% of Return Games Won versus 44.3% for Potapova, with Potapova’s second serve at 45.7%, which will be target number one for the Ukrainian. The clay head-to-head is 1–0 for Kostyuk, a 6–3 6–2 win in Madrid in 2025. On serve, however, the two players are almost identical on all 2026 clay indicators: first serve in at 58.5% each, Service Games Won at 73%, Break Points Saved at 62%. The match will be decided on returns and key moments, where Potapova wins 75% of her tiebreaks while Kostyuk sits at 50% on this surface.

Tonight, every point Potapova plays is worth far more than a point. A win tonight sends her into a WTA 1000 final, the first lucky loser to reach this stage since the format was created in 1990, and a title on Sunday would propel her to 2,065 ranking points, which means the world top 17 and a seeded spot at Roland Garros guaranteed for the first time in her career. From a qualifier knocked out by Kraus ten days ago to potentially being seeded at Porte d’Auteuil next week. Madrid is giving her second chances, and she keeps taking them.
