Coco Gauff withdraws from Tokyo Olympics after testing positive for COVID-19

Gauff was set to compete in her first Olympic Games, and her selection to the U.S. team made her the youngest Olympic tennis player since Mario Ančić made his debut in the 2000 Games in Sydney. 

The 17-year-old became a significant figure for the Americans after Serena Williams announced she would not compete in the Tokyo Olympics following an injury suffered at Wimbledon. In addition, Sofia Kenin pulled out of the Games due to COVID-19. 

This summer's Olympics is missing several big-name tennis players, including Roger Federer, Rafael Nadal, Victoria Azarenka, Angelique Kerber and Bianca Andreescu, among others.
