Coello/Tapia enter as the higher-ceiling pair: more raw firepower, faster point-ending ability, and a proven “close sets” advantage when they control the net. Stupaczuk/Yanguas are a high-pressure, high-volume duo who can drag the match into long exchanges and target transitions, but they must win the side-battle and slow Tapia’s impact. Prediction: Coello/Tapia in two tight sets or three, depending on Stupa/Yanguas’ success with pace management and net denial.
