Leal/Sanz should enter as clear favorites: they’re the more established pair with higher pace in attack and better rally management under pressure. In Riyadh’s typically lively, faster conditions, their ability to accelerate off the glass and finish at the net should translate into more break chances. Expect Jofre/Castaño to compete through grit and lobs, but Leal/Sanz are likelier to win in two tight sets.
