History
The historic Amackassin Club is a privately owned pool and tennis club in Northwest Yonkers founded in 1888 as the Yonkers Lawn Tennis Club. The same year in September the club staged its first tennis tournament. In 1890 the club started an invitation tennis tournament featuring a men's singles event that was won by Victor M. Elting. In 1904 a women's invitation tournament was added to the schedule. In 1920 and 1921 those editions of the tournament were held in conjunction with the Eastern New York State Clay Court Championships with players assuming both titles Eastern New York State Champion and Amackassin Champion. The tournament was part of USNLTA Circuit from 1890 to 1923, then ILTF Circuit from 1923 to 1939. It was discontinued due to World War II.Finals
