Cepero/Benítez come in as the more established, tactically stable pair, likely dictating with heavier bandeja/víbora patterns and better net consolidation. Calleja/Dametto’s best path is to speed up exchanges and create chaos with aggressive returns and quick transitions, but Buenos Aires conditions typically reward patience and controlled volleying. Prediction: Cepero/Benítez in 2 sets, with a tight first set if Calleja/Dametto start fast.
