Brea/Triay arrive as the higher-ceiling pair: Triay’s left-side authority and Brea’s right-side speed/finishing should dictate most neutral exchanges. Fassio/Llaguno will rely on control, lobs, and mistakes forced through patience, but in Riyadh’s typically quicker conditions the initiative pair is favored if they manage errors. Prediction: Brea/Triay win in 2, with a tighter second set if rallies extend.
