Serena Williams took to twitter yesterday afternoon after she was once again "randomly" selected for drug testing, something that she has complained about in the past. Williams, a 23-time Grand Slam champion, says she is "ready to do whatever it takes to have a clean sport," but she's clearly fed up and has accused anti-doping authorities of "discrimination."


She tweeted, "...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 ." She added, "But I’m ready to do whatever it takes to have a clean sport so bring it on. I’m excited."

Williams, 36, has complained before about being drug-tested more than other American tennis players this year. "Just test everyone equally," Williams said on the eve of this year's Wimbledon, according to ESPN. A report by Deadspin said Williams had been checked five times in 2018 by June, more than other U.S. women and men in the sport.

After losing to Angelique Kerger in the Wimbledon Finals, Serena said she had proven to herself that she could still compete to win Grand Slams. According to ESPN, her next Grand Slam title would tie her with Margaret Court for the most with 24, and she already has the most major trophies in the Open era.
