Katie Boulter endured a frustrating start to her campaign at the Japan Women’s Open on Monday after heavy rain forced the suspension of her first-round match against Japanese wildcard entrant Himeno Sakatsume in Osaka. The eighth-seeded British player had to wait until Monday to begin her tournament journey at the WTA 250 event, which got underway over the weekend.

Play was halted shortly after commencement because the venue lacks a protective roof. Tournament officials announced that play would be suspended for at least an hour while spectators were asked to vacate the stands due to the worsening weather conditions. The disruption adds to a lean period for Boulter, who has contested only three matches since September 30, following a second-round exit at the China Open and a first-round defeat at the Wuhan Open.

At the time of the suspension, only three games had been completed, with Sakatsume holding a 2-1 lead in the opening set. Should Boulter manage to turn the match around when play resumes, she will face Switzerland's Viktorija Golubic in the second round, after Golubic secured a straight-sets victory over Japan's Mai Hontama.

While Boulter dealt with weather delays in Osaka, fellow Briton Sonay Kartal celebrated a major milestone after reaching the final of the Wuhan Open. The 24-year-old from London achieved the feat following a six-month injury layoff, a run that elevated her to the position of Britain's new women's number one tennis player.

Kartal captured the opening set of the Wuhan Open final but ultimately fell to Maja Chwalinska, missing out on her first WTA 1000 title. Reflecting on the match after the trophy ceremony, Kartal praised her opponent and expressed gratitude toward her support team, acknowledging that her rapid return to fitness and high-level play exceeded expectations following her long absence from the sport.
