I'm not cheater or thief: Gauff on racist abuse after controversial China Open win. World number four Coco Gauff said she received "insane" amount of racist abuse on social media after her controversial China Open win over China's 16-year-old Sun Xinran. Gauff had stopped play during crucial point after noticing flickering advertising boards, prompting point replay. "You can dislike me or disagree about what happened without being racist...I'm not a cheater or...thief," she said.
