1Target Perez’s side with heavy, high lobs to force backhand overheads and create short balls—Sainz/Eugenio’s best recent swing has come when they win the "lob battle" and take the net on the next ball.
2Extend rallies and attack second volleys: Perez/Martinez’s last-3-month matches show bigger dips in consistency once exchanges go past 6–8 shots, so prioritize depth to feet and patient cross-court patterns before changing direction.
3Protect service games with first-volley quality and avoid rushed bajadas: Sainz/Eugenio should serve-body/serve-T to secure a controllable first volley, while Perez/Martinez need quick net takeover or they’ll bleed break chances against the more stable transition defense.
