"You should be ashamed to insinuate and put this on Patrick! He worked with Serena for years and not once did she test positive for anything! Always find an excuse for white girls cheating," their tweet read.JM@Bridget_OtooYou should be ashamed to insinuate and put this on Patrick!

I have been notified that I have tested positive for a substance named Roxadustat in an extremely low quantity, which came as the biggest shock in my life. Throughout my whole career, the idea of cheating never crossed my mind once, as it is totally against the values I have been educated with. Facing such an unfair situation, I feel completely coonfused and betrayed," Simona Halep tweeted."I will fight until the end to prove that I never knowingly took any prohibited substance and I have faith that sooner or later, the truth will come out. It's not about the titles or money. It's about honor or the love story I have developed with the game of tennis over the last 25 years," she added.
