Day was born in
Colchester, Connecticut, in 1847. Day was founding owner of the independent
New York Metropolitans in 1880 and leased the
Polo Grounds for them to play in, which was the first baseball large-scale venue in Manhattan. In 1883, his
New York Gothams/Giants of the
National League began play at the same site. By 1885, Day concentrated his attentions on the Giants team. Encountering financial difficulties, mainly as a result of the 1890
Players' League revolt, in January 1893 he sold the Giants franchise to
Cornelius Van Cott. Day was the first of two
managers for the
1899 New York Giants, leading the team to a 29–35 record in 66 games played (two contests were ties); he was succeeded by
Fred Hoey. In 1900, Day served as the National League's chief of
umpires. Married twice but without children, Day was interred at
Portland, Connecticut. ==References==
