The read

Maria's high ace rate on grass and the surface's tendency to reward big serving make over 5.5 aces a plausible outcome, though Sebov's low ace count adds uncertainty.

• Maria averages 5.5 aces per match on grass in 2026, with a 5.5% ace rate.
• Sebov's ace rate is only 1.2%, but she may be forced into riskier serves against Maria's return.

The read

Both players have moderate double-fault rates, and the pressure of a grass-court match could push the total over 6.5, though it's a close call.

• Maria averages 3.9 double faults per match, while Sebov averages 3.6, but both have higher rates under pressure.
• In Maria's last 5 grass matches, total double faults have exceeded 6.5 in 3 of them.
• Sebov's second-serve win percentage is only 46.8%, which may lead to more double faults when she goes for bigger second serves.
