A Madrid Open women’s final nobody predicted will crown a first-time champion in the Spanish capital on Saturday, with ninth seed Mirra Andreeva and 26th seed Marta Kostyuk meeting at Manolo Santana Stadium in a match that pits the most consistent teenager in tennis against a Ukrainian playing the best clay of her career.
Neither player has lifted a trophy at La Caja Mágica before. Between them, they are 22-1 on clay this spring. Andreeva, who turned 19 on Thursday, carries a 12-1 record on the surface, her only loss coming to eventual champion Elena Rybakina in Stuttgart.
Kostyuk, the 23-year-old from Kyiv, has not lost a clay match in 2026, going a perfect 10-0 since lifting the Open de Rouen title in mid-April. Strip out Andreeva’s defeat in Germany and the two finalists have gone a combined 21-0 against the rest of the tour on the dirt.
The path
Andreeva navigated the harder half. After byes and routine wins over Panna Udvardy and Dalma Galfi, she escaped Anna Bondar in three sets, took out Leylah Fernández in the quarter-finals, and saved three set points in a second-set tiebreak before closing out Hailey Baptiste 6-4, 7-6 (8) in the semis.
Kostyuk’s run included a third-round upset of world No. 5 Jessica Pegula in straight sets, a clinical quarter-final against Linda Nosková, and a three-set semi against lucky loser Anastasia Potapova.
The history
Kostyuk leads the head-to-head 1-0 after winning their only previous meeting at the Brisbane International in January, 7-6 (7), 6-3 on hard courts. Andreeva is winless against Ukrainian opposition in 2026, having also lost to Elina Svitolina at the Australian Open.
A win on Saturday would make Andreeva the first teenager to reach three WTA 1000 finals since the format was introduced in 2009, and only the sixth player to win each of her first three at the level, joining Kvitová, Svitolina, Garcia, Świątek, and Sabalenka.
The stakes
Kostyuk would become only the second player ranked outside the top 20 to win Madrid, after Aravane Rezai in 2010. Whichever way the match ends, Kostyuk jumps from No. 22 to No. 9 in the Race to the WTA Finals; Andreeva moves to third with a win, fourth with a loss. The champion takes home €1,007,165 and 1,000 ranking points heading into Rome.
