Tello/Alonso bring big power and first-strike potential, but they’ll face a more “system” pair in Yanguas/Stupaczuk with elite transition play and heavier rally tolerance. In Gijón’s typically slower, indoor-controlled P2 conditions, construction and countering tend to beat pure pace, favoring Yanguas/Stupa if they manage Tello’s overheads. Prediction: Yanguas/Stupaczuk in 2 tight sets or 3 if Tello dominates short bursts.
