Only one player has won the American tennis title on all surfaces, namely - grass, clay, synthetic. Name that player.
Jimmy Connors holds a record unique to US Open competition and one that will probably never be matched, much less broken. He is the only player, male or female, to win the singles championship on three different surfaces. Connors won twice at the West Side Tennis Club in Forest Hills-on grass in 1974 and on clay (Har-Tru) in 1976-before capturing his third championship on hard court (DecoTurf II) at the USTA National Tennis Center in 1978.
