This matchup pits Sanyo’s elite left-side craft and tempo control (with Alfonso as the more aggressive finisher) against a likely more direct, high-tempo pair in Martínez/Valenzuela who will try to win with speed and first-strike volleys. In Gijón’s typically indoor/quick P2 conditions, the team that dominates serve + first two shots and protects their backhand corner under pressure should edge it. Tactical advantage leans Sanyo/Alfonso if they can slow rallies, target Martínez under lobs, and avoid trading flat exchanges early.
