1Target the right-side channel: Riera’s left-handed forehand from the backhand corner can dominate cross-court; Fassio/Llaguno must avoid feeding that lane with predictable lobs and instead vary with lower, faster bandeja-height balls into Navarro’s feet to stop early net takes.
2Serve/return micro-battle: Fassio/Llaguno need high first-serve percentage and body serves to reduce Riera’s aggressive return positioning; Riera/Navarro should step in on second serves and attack the middle seam to force rushed volleys and generate early-break chances.
3Net protection vs. lob pressure: Llaguno must win the first volley exchange by volleying deep through the center and using controlled chiquitas to deny Riera/Navarro easy counter-lobs; Riera/Navarro should test Fassio’s overheads repeatedly and extend points to draw short lobs, then punish with high-percentage viboras to the open court.
