Serena Williams says she is being discriminated against with the frequency she has to go through drug testing.
Williams took to Twitter on Tuesday saying she was again selected for an anti-doping test.
“And it’s that time of the day to get ‘randomly’ drug tested and only test Serena. Out of all the players it’s been proven I’m the one getting tested the most. Discrimination? I think so. At least I’ll be keeping the sport clean," Williams tweeted.
“But I’m ready to do whatever it takes to have a clean sport so bring it on. I’m excited," she added.
