This Buenos Aires P1 matchup pits the younger, more volatile Alfonso/Barahona against the veteran control pair Sanyo Gutiérrez/Víctor Ruiz, a duo built to win long tactical exchanges. In likely slower Argentine conditions, Sanyo’s tempo management and Ruiz’s finishing from the left should blunt the underdogs’ pace and force them into low-percentage risk. Prediction: Sanyo/Ruiz in 2 tight sets unless Alfonso/Barahona dominate early with aggressive net pressure.
