Arce/Tello project a high-ceiling blend of left-side creativity and right-side power, suited to a Major where first-strike padel is rewarded. Sanz/Nieto typically win through structure: long rallies, clean transitions, and forcing opponents to hit one extra ball under pressure. Slight edge to Arce/Tello if they control the net early; if rallies extend and errors rise, Sanz/Nieto can flip it.
