Recap
The New York Knickerbockers were one of the first organized baseball teams which played under a set of rules similar to the game today. Founded as the "Knickerbocker Base Ball Club" by Alexander Cartwright in 1845, the team remained active until early 1870s.
The formation of the Knickerbockers club across the Hudson River created a division in the group of Manhattan players. According to Wheaton, "The new game quickly became very popular with New Yorkers, and the numbers of the club soon swelled beyond the fastidious notions of some of us, and we decided to withdraw and found a new organization, which we called the Knickerbocker." Membership in the Knickerbockers was by invitation and required the payment of dues; those Gothams or "New Yorks" who were excluded continued to play among themselves.
What was long considered the first "officially recorded" baseball game was played on June 19, 1846 at the Elysian Fields in Hoboken, New Jersey. The "Knickerbockers" and the "New York Nine" (also known as the New York Baseball Club, probably identical with the Gothams), played with Cartwright's twenty rules. Cartwright's team, the Knickerbockers, lost 23 to 1 to the New Yorks in four innings. Some say that Cartwright's team lost because his best players did not want to make the trip across the river. Cartwright was the umpire during this game and fined one player six cents for cursing.
