Perth, Australia –

Four-time Grand Slam champion Naomi Osaka got her 2026 season off to a winning start for Japan in the United Cup, after Great Britain’s Emma Raducanu pulled out of their singles clash with a fitness issue.

But despite Osaka’s win, GB took the match 2-1 with a deciding mixed doubles victory.

Osaka was too strong for GB reserve and 276th-ranked Katie Swan, winning 7-6 (7/4), 6-1 as Raducanu watched from the sidelines.
