In Riyadh’s typically fast, low-bounce outdoor conditions, Alfonso/Sanyo project as the more stable pair: Sanyo’s control and tempo management should reduce errors and force Martinez/Valenzuela into low-percentage exchanges. Martinez/Valenzuela can threaten if they win the serve-first patterns and convert early break chances, but over a full match the veteran pair’s decision-making in key points is favored. Prediction: Alfonso/Gutiérrez in 2, with a tighter second set if Martinez/Valenzuela start hot.
