Osaka pulls out in Tokyo with abdominal pain


Naomi Osaka’s title defence at her home Pan Pacific Open ended on Thursday when the former world number one withdrew ahead of her second-round match against Beatriz Haddad Maia due to abdominal pain.

The four-time Grand Slam champion, has apologised for not being able to compete.

It was the latest setback for the 24-year-old, who sat out the entire grasscourt season with an Achilles injury and also retired from her first-round match in Toronto with a back problem in the lead-up to the U.S. Open.
