Naomi Osaka has pulled out of next week’s Berlin WTA grasscourt tournament in the wake of her controversial exit from the French Open, organisers confirmed Monday.

“We have received notification that Naomi Osaka cannot start in Berlin. After consulting her management, she will take a break,” said a spokesman for the Berlin tournament, which starts June 14.

Osaka has not said when she plans to play next, casting doubt on her participation at Wimbledon, which starts on June 28, and the Tokyo Olympics.
