Katie Boulter is on the brink of reclaiming the British No 1 ranking after advancing to the quarter-finals of the Japan Open. In a commanding performance, Boulter defeated Viktorija Golubic with a score of 6-2, 6-1, completing the match in under an hour despite facing challenging conditions.

This victory marks Boulter's third consecutive day of play in Osaka, following her earlier triumph over Himeno Sakatsume with a score of 6-3, 6-1 in the first round, which also faced interruptions due to rain.

Boulter now prepares to face either Antonia Ruzic or Kayla Day for a chance at the semi-finals. Her impressive run comes on the heels of Sonay Kartal's breakthrough at the Wuhan Open, where Kartal defeated several top-50 players to reach her first major final. Although Kartal ultimately fell to Maja Chwalinska, the runner-up at the French Open, she ascended to No 50 in the world, overtaking Boulter as British No 1.

Should Boulter reach the semi-finals in Japan, she would not only reclaim her national ranking but also re-enter the world's top 50. Reflecting on her performance against Golubic, Boulter expressed satisfaction with how she managed the windy conditions, stating, “Really difficult conditions. I’m very pleased that I didn’t allow that to affect me today and I think I ended up playing some really good tennis in the second set.”
