Sanz/Nieto come in as the more established, structurally solid pair and should be favored over Jensen/Hernandez, who likely rely on streaky attacking bursts and speed. In Miami P1 conditions (often warm, lively ball), the match should hinge on whether the underdogs can win fast points and disrupt rhythm. Prediction: Sanz/Nieto in 2 sets if they control serve-return patterns and the right-side tempo.
