In 1976, Richards' gender reassignment was outed by local TV anchor Richard Carlson, the father of Tucker Carlson. Subsequently the United States Tennis Association (USTA), the Women's Tennis Association (WTA), and the United States Open Committee (USOC) required all female competitors to verify their sex with a Barr body test of their chromosomes. Richards applied to play in the US Open in 1976 as a woman, but refused to take the test, and thus was not allowed to compete in the Open, Wimbledon, or the Italian Open in the summer of 1976.
