Orsi/Llaguno come in as the more proven pair at P1 level, with a steadier high-percentage game suited to Buenos Aires’ typically slower, grippier conditions. Manquillo/Aguilar can compete if they win the speed exchanges and avoid prolonged neutral rallies, but they’ll be tested on patience and shot selection. Prediction: Orsi/Llaguno in 2 sets, with one tight set decided by break-point efficiency.
