Katerina Siniakova dominated Ashlyn Krueger at the Japan Open, winning 6-1, 6-0 in just 64 minutes to claim her first singles title since 2021. Siniakova never let Krueger settle into a rhythm, breaking serve repeatedly and converting her chances on the rare occasions Krueger held a game close. The Czech player's aggressive baseline game proved too much for her opponent to handle in straight sets.

This title marks a significant return to form for Siniakova, who has spent the last three years chasing another breakthrough moment. She showed no rust on the Tokyo hard courts, posting a masterclass in efficiency. Krueger had a solid run through the draw to reach the final, but ran into a player firing on all cylinders when it mattered most.
