Japan’s Naomi Osaka announced she was withdrawing from the French Open in the wake of her decision to boycott post-match media duties at the Grand Slam tournament.

“The best thing for the tournament, the other players and my well-being is that I withdraw so that everyone can get back to focusing on the tennis going on in Paris,” the four-time Grand Slam title winner wrote on Twitter.

Osaka was fined $15,000 on Sunday by Grand Slam organizers for failing to attend a news conference following her first-round win against Romanian Patricia Maria Tig.

In the run-up to the claycourt major, the four-time Grand Slam champion and sport’s highest-earning female athlete announced she would boycott news conferences while in Paris to raise awareness of players’ mental well-being, saying the nature of questions from journalists is like “kicking a person when they are down”.

Earlier, the board of the four Grand Slams said in a statement that the French Open organizers had asked Osaka to reconsider her position and tried unsuccessfully to speak with her to resolve the matter.

“We have advised Naomi Osaka that should she continue to ignore her media obligations during the tournament, she would be exposing herself to possible further Code of Conduct infringement consequences,” said a statement from the four Grand Slam tournaments.
