Ortega/Calvo should control most phases through higher tempo at the net and cleaner transition work, especially in Buenos Aires’ typically lively indoor/outdoor conditions that reward aggressive volleying. Fassio/Eugenio will need long, physical rallies and targeted serving patterns to prevent Ortega from dictating with first volleys. Prediction: Ortega/Calvo in 2 sets, with risk if they get dragged into slow side-wall exchanges.
