The Original 9 were a group of nine women's professional tennis players who broke away from the governing bodies of tennis in 1970 to launch their own professional tour, the Virginia Slims Circuit, which later evolved into the modern WTA Tour.
"BJ and Rosie were the ringleaders on court, close friends, doubles partners frequent final–round foes, super saleswomen for the emerging tour. They were perfect role players, feisty but good humored kids off the public courts who believed women had a destiny in professional sport."[1]
"We knew we were making history and we had such a strong sense of purpose. I just kept thinking about the vision we had for the future of our sport. We wanted to ensure that any girl in the world that was good enough would have a place to go and make a living playing tennis."
Billie Jean King speaking in 2010.[6]
Two other players withdrew from the event: Patti Hogan withdrew because she did not want to take the risk and stand against the establishment. Margaret Court, who, after completing her Grand Slam, had just lost in Charlotte to Chris Evert, who was 15 at the time, withdrew due to a left ankle injury which sidelined her for three months. She was replaced by Pigeon.[11][2]
