<P> In 1978 the tournament moved from the West Side Tennis Club , Forest Hills , Queens to the larger USTA National Tennis Center in Flushing Meadows , Queens , three miles to the north . In the process , the tournament switched the court surface from clay , used in the last three years at Forest Hills , to hard courts . Jimmy Connors is the only individual to have won US Open singles titles on all three surfaces ( grass , clay , hardcourt ) , while Chris Evert is the only woman to win on two surfaces ( clay , hardcourt ) . The US Open is the only Grand Slam tournament that has been played every year since its inception . During the 2006 US Open , the complex was renamed the USTA Billie Jean King National Tennis Center in honor of four - time tournament champion and women 's tennis pioneer Billie Jean King . </P>
