Serena Williams shard a series of tweets in which she said she as a victim of “discrimination” after recently finding out that she’s the most drug tested tennis player in America.

The 23-time Grand Slam singles champion took to social media to air her thoughts on Tuesday.

“..And it’s that time of the day to get “randomly” drug tested and only test Serena,” she tweeted. “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.”

She added: “But I’m ready to do whatever it takes to have a clean sport so bring it on. I’m excited.”
