American tennis player Taylor Townsend said on Monday that she has been repeatedly mistaken with other black players when out on the WTA Tour all over the world.

"Everybody sees a black person and they assume that it's Venus or Serena (Williams) or Sloane (Stephens). I've been (mistaken for) literally all of them down the list except for myself," said the world number 73.

"I'm walking through and somebody has to check my bag. Check my credentials, check my coach's bags, check my coach's credentials. It's extra security, extra precautions that need to be taken to make sure that I belong. This is our reality, it happens all the time," added the 24-year-old about the discriminatory behaviour that she faces while on tour.
