Salazar/Alonso enter as the more structured, higher-ceiling pair: Salazar’s control in the forehand lane and net management should dictate tempo, while Alonso can finish points when openings appear. Arruabarrena/Lobo need a high-volume, physical match and disruptive variations to avoid getting pinned in defense. In Riyadh’s typically faster, dry conditions, the favorite edge goes to Salazar/Alonso in two competitive sets.
