Baptiste, ranked No. 32, rides massive momentum from saving six match points to stun World No. 1 Aryna Sabalenka in quarters—her first top-5 win and maiden WTA 1000 semifinal—but faces stylistic challenges against Andreeva's baseline power, with their head-to-head tied 1-1 from 2025 grass encounters. No injury concerns for either on high-bouncing clay.",
