Coco Gauff calls out 'insane' racist comments after 16-year-old opponent gets emotional following controversy

Coco Gauff found herself in some controversy in her match at the China Open against 16-year-old Sun Xinran, who was playing on home soil.

Gauff stopped a rally after electronic advertising boards lining the court flickered during a point late in the first set of her 7-5, 6-1 third-round victory over Xinran, a 16-year-old who recently won the U.S. Open junior title.

Sun appeared about to win the point when Gauff stopped playing, but the chair umpire then ordered the point to be replayed.
