No.4 seed Osaka on Wednesday defeated No.12 Anett Kontaveit 4-6, 6-2, 7-5 victory to enter the semifinal where she was slated to face Elise Mertens on Thursday afternoon.

"Hello, as many of you are aware I was scheduled to play my semi-finals match tomorrow," Osaka wrote in a statement on her social media accounts. "However, before I am an athlete, I am a black woman. And as a black woman I feel as though there are much more important matters at hand that need immediate attention, rather than watching me play tennis.

"I don't expect anything drastic to happen with me not playing, but if I can get a conversation started in a majority white sport I consider that a step in the right direction. Watching the continued genocide of Black people at the hand of the police is honestly making me sick to my stomach. I'm exhausted of having a new hashtag pop up every few days and I'm extremely tired of having this same conversation over and over again. When will it ever be enough?" she added.

The National Basketball Association's Milwaukee Bucks and Orlando Magic also boycotted their playoff game on Wednesday afternoon following the shooting of Blake by police in Kenosha, near to Milwaukee.
