In this matchup between Ekaterina Alexandrova and Marta Kostyuk, Marta Kostyuk is the favorite. Although Ekaterina Alexandrova currently leads their head-to-head record 2–1, I believe Marta Kostyuk will turn things around today. Even though Kostyuk has struggled in her recent matches—having been recovering from an injury—my prediction is a win for Marta Kostyuk, with a final score of 1–2.

In this match between Adrian Mannarino and Andrey Rublev, Andrey Rublev is the favorite. He leads their head-to-head record 5–1, and he is also ranked higher than his opponent—Rublev sits at 22nd place, while Mannarino is in 79th. Therefore, my prediction is a win for Andrey Rublev.

In this matchup between Facundo Diaz Acosta and Nikoloz Basilashvili, Nikoloz Basilashvili is considered the favorite. However, the two have never faced each other before; Facundo Diaz Acosta is ranked significantly higher than his opponent, and he also won his previous match against a higher-ranked player. Therefore, I predict a victory for Facundo Diaz Acosta, with a score of 2–1.
