Rufo/Calstelló project as the steadier pairing in Valladolid’s faster indoor-style conditions, with more reliable transition work and a higher floor under pressure. López Moral/Touly can swing the match if they win the aerial battle early (serve + first volley) and keep points short, but they risk leaking errors if dragged into long cross-court exchanges. Slight edge to Rufo/Calstelló in two tight sets if they control the left-side tempo and protect their second serves.
