Editorial Prediction (August 3, 2025, UTC):

As the upcoming match approaches, recent statistics and historical performance provide a guiding light for predicting the likely winner. Kozlov, with his marginally superior second serve performance and slightly better breakpoint conversion rate, demonstrates a consistent edge in crucial game moments.

Meanwhile, Ramanathan's experience on hard courts and success in head-to-head matchups indicate he is not to be underestimated. Although Ramanathan leads in second serve return points in recent form, Kozlov's efficiency in first serve returns may neutralize this advantage.

Considering the combined elements of head-to-head history and recent form, Kozlov emerges as the more in-form player, suggesting that Kozlov is most likely to clinch victory in this upcoming encounter.
