Yastremska's recent second-round exits in Charleston (clay win over Zakharova before Bencic loss) and Miami highlight her power game suited to Madrid's high altitude, while Sierra's retirement in Charleston and hard-court struggles suggest vulnerability, though her South American clay roots could aid baseline rallies. No injuries reported; trader consensus weighs Yastremska's firepower against Sierra's upset potential in best-of-three sets.
