Taylor Townsend, Jelena Ostapenko engage in heated U.S. Open exchange...

"Wow how many messages I received that I am a racist. I was NEVER racist in my life and I respect all nations of people in the world, for me it doesn't matter where you come from," she posted. "There are some rules in tennis, and unfortunately, when the crowd is with you, you can't use them in a disrespectful way to your opponent. Unfortunately for me, coming from such a small country, I don't have that huge support and a chance to play in my homeland. I always loved to play in the U.S. and the U.S. Open, but this is the first time someone is approaching the match this disrespectful way."
