Mirra Andreeva holds a narrow trader consensus edge at 55.5% implied probability over Marta Kostyuk (44.4%) heading into the WTA 1000 Madrid Open women's singles final on clay, reflecting their parallel dominance this season—Andreeva at 12-1 on the surface, Kostyuk a perfect 11-0 entering her first career WTA 1000 championship match. Yesterday's semifinals solidified the matchup: ninth-seeded Andreeva saved three set points to outlast Hailey Baptiste 6-7(7), 6-3, 7-6(4), while 26th-seeded Kostyuk rebounded from a second-set lapse for a 6-2, 1-6, 6-1 win over Anastasia Potapova. With Kostyuk leading their lone prior head-to-head and both thriving at high-altitude La Caja Mágica, the closely contested final underscores stylistic clashes in baseline power and defense, absent major injury concerns.
