Diestro/Sánchez Blasco project more stability in structured points and should benefit if Brussels plays slower/ball-heavy, where defense-to-attack transitions matter most. Sanz/Nieto can swing the match if they win the first volley exchanges and keep Diestro off comfortable forehand patterns, but they tend to be more momentum-dependent. Lean: Diestro/Sánchez Blasco in a tight match, likely decided by break-point conversions and net control.
