Anisimova relies on her consistency, heavy groundstrokes, and impressive court coverage. Osaka’s offensive firepower can dominate rallies early, but the American’s ability to absorb and redirect pressure makes her a threat from the back of the court.
Based on the latest serving stats from the WTA website:
- Osaka has served 226 aces, won 77.9% of her service games, and won 32.3% of her return games, with a 73.5% win rate on her first serves.
- Anisimova has recorded 145 aces, won 70.6% of her service games, won 38.3% of her return games, and has a 65% first-serve win rate.

Considering Osaka’s superior serve numbers and hard-court Grand Slam experience, paired with Anisimova’s return advantage and recent form, this match is setting up to be a classic clash of power versus retrieval.
Nonetheless, Osaka’s aggression could be the deciding factor if she takes early control. If not, Anisimova’s steadiness and depth could grind Osaka into uncomfortable, extended rallies.
Prediction: Osaka to win in three sets
