Salazar/Alonso bring a higher baseline of top-level decision-making and net management, which typically decides P1 matches in Valencia’s generally fast, lively conditions. Fassio/Eugenio can compete by extending rallies and targeting the less-established link under pressure, but they’ll need near-perfect discipline to avoid giving Salazar free transition opportunities. Slight edge to Salazar/Alonso, especially if they win the first set and control tempo from the net.
