Destanee Aiava has announced her retirement from tennis at 25, saying it had a "racist, misogynistic, homophobic and hostile" culture.
The Australian, who has Samoan heritage, said the sport was like a "toxic boyfriend" - and that this would be her final season on tour.
Aiava, who reached a career-high singles ranking of 147, posted an expletive-laden statement on Instagram to explain her decision.
"My ultimate goal is to be able to wake up every day and genuinely say that I love what I do - which I think everyone deserves a chance at," she said.
