Marta Kostyuk rides a perfect 10-match clay winning streak into the Madrid Open semifinals, capped by her Rouen title last week and straight-set triumphs over Yulia Putintseva, Jessica Pegula, and No. 13 seed Linda Noskova (7-6(1), 6-0 in the quarters)—the only player yet to drop a set here. No. 23-ranked Kostyuk meets lucky loser Anastasia Potapova (No. 56), whose upset run includes straight-set takedowns of Shuai Zhang, No. 2 Elena Rybakina, and Karolina Pliskova for her first WTA 1000 clay quarterfinal. Even 2-2 head-to-head favors Kostyuk's 9-0 clay record in 2026 on these high-altitude courts, shaping trader consensus amid no reported injuries.
