Sanz/Nieto bring a steadier, percentage-based build with strong transition work, while Tello/Arce lean on heavier first-strike padel (serve/return + early volleys) and power to shorten points. Buenos Aires conditions typically reward weight of shot and kick off the back glass, which suits Tello’s left-side aggression but also demands clean decision-making under pressure. Slight edge to Sanz/Nieto in tight moments due to structure and consistency, but if Tello/Arce dominate first two balls they can flip it.
