They say lightning doesn’t strike twice, but for Anastasia Potapova, the 2026 Mutua Madrid Open has been one long, electric storm. Just one week after losing in the final round of qualifying, the Russian-born Austrian has rewritten the record books.
By overcoming former World No. 1 Karolina Pliskova 6-1, 6-7(4), 6-3 on Wednesday, Potapova became the first lucky loser in history to advance to a WTA 1000 semifinal since the format was introduced. In a contest that veered from complete control to a psychological collapse, Potapova managed to withstand wasting three match points and trailing 3-1 in the final set, extending her Cinderella run.

The match began to slip away from Potapova in the second set. After cruising through the first in just 23 minutes, her nerves betrayed her. She double-faulted away match points and found herself trailing 3-1 in the final set.
Today, he just told me to shut up, to keep on working, to start working with my legs. And that we are both here together in this match, I'm not just by myself. It just happened at such important moment, and it gave me a lot of energy. Mentally, I think he got this match. I did it physically. He did it mentally.Anastasia Potapova
Enter her boyfriend, ATP pro Tallon Griekspoor. Arriving in the player box just in time for the third set, his "coaching" was effective. Following this intervention, Potapova won 16 of the last 18 points of the match, silencing the comeback attempt from Pliskova.
Potapova’s performance is statistically remarkable for a lucky loser. She has now recorded three straight victories over former World No. 1 players or Grand Slam champions.
3rd round: Defeated Jelena Ostapenko.
4th round: Stunned World No. 2 Elena Rybakina.
Quarterfinal: Outlasted Karolina Pliskova.
For Potapova, who is now the first player representing Austria to reach a WTA 1000 semi since Sybille Bammer in 2007, the journey feels like a gift she isn't taking for granted.
First LL: No lucky loser has reached a semifinal at this level since the Tier system began in 1990.
Mental reset: Potapova admitted her 2nd-set collapse was due to an inability to "manage my nerves," a candid admission heard from players during a deep run.
Next challenge: She faces Marta Kostyuk in the semifinals. Kostyuk c is undefeated on clay this season and defeated Potapova in Madrid last year.
WTA 500 momentum: This run backs up her recent form, having reached the final in Linz three weeks ago.
Anastasia Potapova has shown that in tennis, the way you finish matters more than how you begin, or even how you stumble in qualifying. Drawing on a mix of stern encouragement from her team and an unyielding baseline game, she has transformed the disappointment of qualifying defeat into a landmark achievement. Whether she can solve Kostyuk’s clay-court prowess is still uncertain, but for now, the so-called “Lucky Loser” stands as the most dangerous player in Madrid.
