Brea/Triay arrive as the higher-ceiling pair: Triay’s control and smash threat plus Brea’s speed in transition should set the rhythm in Buenos Aires conditions. Martinez/Sainz can compete by slowing the match with heavy bandejas and disciplined lobs, but they’ll need long rallies and low error to avoid getting pinned. Slight edge to Brea/Triay, especially if they win the middle-lane exchanges and impose early momentum.
