Diestro/Sanchez should enter as the steadier, higher-ceiling pair: Diestro’s left-side construction plus Maxi’s veteran control typically translates well in Buenos Aires’ heavier, slower conditions. Jofre/Gala can compete if they speed up points with early volleys and targeted lobs, but they’ll need sustained first-strike efficiency to avoid long defensive stretches. Prediction: Diestro/Sanchez in 2 tight sets, with momentum swings driven by who wins the lob-and-net battle.
