Brea/Triay come in as the more established, higher-ceiling pairing: elite left-side control plus heavy finishing should translate well to Miami’s typically quicker, lively conditions. Sainz/Eugenio can compete if they slow the match with precise lobs and win the long neutral exchanges, but they’ll be under constant pressure on serve and at the net. Prediction: Brea/Triay in 2 sets, with a tight opening set if Sainz controls tempo early.
