Serena Williams complained on social media that she wanted to re-test Serena, as she again criticized the frequency with which she was selected for anti-doping testing.
The 23-time Grand Slam champion joined Twitter Tuesday night after receiving another visit from a tester
… and it's this time of the day to get "random" drug testing and only to test Serena. All players have proven that I am the one who is tested the most. Discrimination? I guess so. At least I'll keep the sport clean #StayPositive

Williams complained earlier this year that he is being tested for drugs more than any other American tennis player.
"Just try it all out the same way," Williams said on the eve of this year's Wimbledon, losing to Angelique Kerber in the final.
According to a report by Deadspin, Williams was scored five times in June 2018, more than other US women and men in the sport.
Williams returned to the competition this season after spending more than a year missing for pregnancy and maternity leave. She gave birth to a daughter last September.
As part of the US Anti-Doping Agency's anti-doping agency's "smart" testing program, it's not uncommon for top athletes – those who were successful in their sport – to be tested more often than others.
Following her loss to Kerber, Williams said she proved to herself that she still could compete to win Grand Slams. Her next Grand Slam title would put her at 24 with Margaret Court most. She already has the biggest trophies in the open era.
