Augsburger/Lebrón should have the higher ceiling: Augsburger’s power from the left plus Lebrón’s transition game typically translates well in Buenos Aires’ often heavier conditions if they stay patient. Ruiz/Esbrí can make it ugly with volume, lobs and counterpunching, but they’ll need to neutralize the first-strike patterns and win long exchanges. Prediction: Augsburger/Lebrón in 2–3 sets, with tiebreak risk if conditions slow the ball down.
