Four newcomers, one final berth

The Mutua Madrid Open has reached its semifinal stage with a quartet of players who have never before contested a final at this tournament. On Thursday, Mirra Andreeva takes on Hailey Baptiste in the day session, while Marta Kostyuk faces lucky loser Anastasia Potapova under the lights at Estadio Manolo Santana. All four women are vying for their first appearance in a Madrid final on the WTA Tour Driven by Mercedes-Benz. The tournament, which has been marked by a series of upsets, now offers an unexpected opportunity for each semifinalist to claim the biggest title of her career.

Baptiste's revenge tour continues after stunning Sabalenka

No upset has been more dramatic than Baptiste's quarterfinal comeback against world No. 1 Aryna Sabalenka. The American, ranked 32nd, saved six match points en route to a 2-6, 6-2, 7-6(6) victory — her first career win over a top-five opponent. Baptiste described the tournament as a "revenge tour" after avenging her quarterfinal defeat to Sabalenka in Miami last month. On Thursday, she faces Andreeva, who eliminated her in the third round of Wimbledon last year. That match, which Andreeva won 6-1, 6-3, is their only prior meeting.

Andreeva aims to extend head-to-head edge

Mirra Andreeva, the eighth seed, holds a 1-0 head-to-head record against Baptiste after their Wimbledon encounter. The 18-year-old Russian has been in strong form on clay and will look to use her aggressive baseline game to dictate play. Baptiste, meanwhile, has already matched her best tournament performance by reaching the semifinals, equaling her run in Abu Dhabi in February. She is also the lowest-ranked player to come back from a set down to beat a world No. 1 on clay in the last 40 years.

Kostyuk and Potapova meet in night session

In the night session, Marta Kostyuk continues her undefeated start to the clay season against Anastasia Potapova, who entered the main draw as a lucky loser. Potapova made history by becoming the first lucky loser to reach a WTA 1000 semifinal. Kostyuk, who has not lost a match on clay this year, advanced to the semifinals with a quarterfinal win. Potapova quelled Karolina Pliskova in the previous round to set up the encounter.

High stakes for all four semifinalists

For each player, Thursday's match represents a chance to break new ground. Andreeva is seeking her first Madrid final after a breakout season that included a deep run at Wimbledon. Baptiste, who saved six match points against Sabalenka, has shown remarkable resilience. Kostyuk's undefeated clay record makes her a formidable opponent, while Potapova's run as a lucky loser adds an element of unpredictability. The winner of each semifinal will advance to the final, scheduled for Saturday.
