Hailey Baptiste's stunning quarterfinal upset over World No. 1 Aryna Sabalenka—saving six match points in a 2-6, 6-2, 7-6(14) thriller—has fueled her improbable run to the Madrid Open semifinals on clay, where she boasts a career WTA record of 16-15 and four straight wins this week. Mirra Andreeva, the eighth seed and world No. 8, advanced past Leylah Fernandez in straight sets after saving three set points, extending her strong clay form following a recent Stuttgart quarterfinal victory over Iga Swiatek. The pair split their prior two meetings, with Andreeva winning their latest clash at Wimbledon; Baptiste enters less rested after her grueling QF, while altitude and high-bouncing clay at La Caja Magica could amplify both players' powerful groundstrokes in this first-time Madrid semifinal matchup.
