Ayats/Perino look like the more structured pair for a FIP Gold setting: higher rally tolerance, clearer roles, and better point construction under pressure. Mena/Archieri can spike the match with aggressive starts and quick transitions, but they’ll need sustained accuracy in Shanghai’s typically faster indoor-style conditions. Prediction: Ayats/Perino in 2–3 sets, edge in tight moments via steadier side-to-side control and smarter lob/volley sequencing.
