Triay/Brea project as the more structured, higher-ceiling pair: Triay’s left-side control and transition game should create steady pressure for Brea to finish. Ustero/Sánchez can win stretches with Sánchez’s experience and Ustero’s speed, but they must resist being pinned in the right-corner and rushed on short lobs. In Riyadh’s typically quicker, lower-bounce conditions, the edge leans Triay/Brea in two tight sets if they dominate the middle early.
