With Billie Jean King she won the Wimbledon and US doubles in 1967. In 1970 she joined the players who broke away over prize money and won the first Virginia Slims event in Houston, the start of the women's professional tour. She reached the US Open singles final in 1970 and 1971, losing to Margaret Court and King, won 112 professional doubles titles, the last with Martina Navratilova in 1988, and played World TeamTennis for nine teams.
