Waltert advanced via qualifying wins over Despina Papamichail and a straight-sets victory over Oleksandra Oliynykova in the first round, showcasing improved form on the outdoor clay surface. The pair meets for the first time with no head-to-head history; Ostapenko's powerful baseline game suits Madrid's high-altitude conditions, though her recent Stuttgart first-round loss to Mirra Andreeva highlights vulnerability to aggressive play. No reported injuries for either, but Waltert's momentum as an underdog adds upset intrigue ahead of potential weather impacts.
