Bergeron/Fonteny should control this matchup with a clearer top-end structure: Bergeron’s experience and Fonteny’s pace typically translate well in FIP Silver tempo. Sintes Villalonga/Santigosa can compete if they extend rallies and force uncomfortable transitions, but they’ll need sustained efficiency in serve-return phases. Prediction: Bergeron/Fonteny win in 2, with danger if they start slowly.
