Stupaczuk/Yanguas come in as the higher-ceiling pair: more speed in transition, heavier bandeja/vibora pressure, and better ability to turn defense into attack—key in Asunción’s typically lively conditions. Diestro/Maxi can compete by slowing the tempo and forcing long, positional rallies, but they’ll need near-perfect net management to avoid getting stretched. Slight edge to Stupa/Yanguas in two tight sets if they establish early net dominance and target Maxi’s mobility.
