Davis and partner Holcombe Ward won the U.S. men's doubles championship in tennis three years in a row from 1899-1901. In 1900, he developed the structure for and donated a silver bowl to go to the winner of a new international tennis competition designed by him and three others known as the International Lawn Tennis Challenge, which was later renamed the Davis Cup in his honor. He was a member of the U.S team that won the first two competitions in 1900 and 1902 and was also the captain of the 1900 team.
