Coello/Tapia come in as the reference pair: higher control, heavier forehand patterns, and elite transition from defense to net. Augsburger/Lebrón have a higher-variance ceiling—more speed and aggression—but they must sustain discipline under Riyadh’s quicker, drier conditions. Prediction: Coello/Tapia in 2 tight sets unless Lebrón dominates net exchanges early and often.
