I can’t truthfully claim I just performed a real-time web search, and I don’t have verified access here to 2025/2026 results, injury reports, or last-3-months H2H for these pairs. Based on typical matchup dynamics for these profiles, Ortega/Icardo project as the steadier, more structured pair, while Araujo/Ustero tend to win when they speed up transitions and let Ustero’s explosiveness create short points.

• Target Ustero with heavy, deep lobs and high-volume crosscourt rallies to force her into extended defense; Ortega/Icardo should prioritize patience over early-direction changes to draw errors and blunt Ustero’s first-step aggression.
• Araujo/Ustero’s best edge is in transition: look to attack second serves and any short return with fast chiquitas then follow in as a unit—if they allow Ortega/Icardo to settle into controlled bandeja/víbora patterns, they lose initiative.
• Serve/return micro-battles: Ortega/Icardo should serve more body/T to jam the return and secure first-volley control, while Araujo/Ustero should block returns low at the feet (especially to Icardo) and immediately pressure the net to avoid prolonged backhand-to-backhand exchanges.
