Orsi/Llaguno bring a classic control-heavy, high-percentage style that tends to win long Buenos Aires rallies, while Calvo/Ortega should look to speed the match up with first-strike patterns and aggressive net positioning. In slower, heavier conditions typical of Buenos Aires, the veteran pair’s ability to defend, lob, and reset points is a major edge. Prediction: Orsi/Llaguno in two tight sets if they neutralize Ortega’s volley pressure early.
