Chingotto/Galán enter as the more stable, higher-ceiling pairing: Galán’s left-side power plus Chingotto’s right-side defense usually wins the long Buenos Aires rallies. Sanz/Nieto can compete if they disrupt rhythm and finish quicker points, but sustained neutral exchanges generally favor Chingotto/Galán. Prediction: Chingotto/Galán in 2 tight sets, with breaks decided by Galán’s overhead efficiency.
