Katie Boulter exits Japan Open in semi-final loss to Katerina Siniakova

OPA WIRE, Oct 24 (OPA) — Katie Boulter’s campaign at the Japan Open ended in the semi-finals with a 6-1, 6-4 loss to doubles world number one Katerina Siniakova. The match, which lasted 85 minutes, denied the 30-year-old Briton a chance to compete for her fifth WTA singles title.

Siniakova dominated the opening set before Boulter mounted a brief recovery, securing an early break in the second set. However, the Czech player responded with two decisive breaks to seal the victory. Boulter entered the tournament following a brief period where Sonny Kartal held the British number one spot after a strong performance at the Wuhan Open.

Despite the semi-final exit, Boulter’s progression through the Osaka draw—highlighted by a quarter-final victory over Antonia Ruzic—is sufficient to surpass Kartal in the upcoming world rankings update. The result marks a return to form for Boulter, who had been aiming to capitalize on her momentum in Japan.

Siniakova advances to Sunday’s final, where she will face 2023 champion Ashlyn Krueger. Krueger secured her place in the title match after defeating top seed Ann Li in a three-set contest, finishing 6-4, 6-7 (4-7), 6-3.
