June 19th

On this day - June 19th 1846 - The first official organized Baseball game 

New York Nine won against New York Knickerbockers 23-1 in the first official organized Base ball game. The Game was played in Hoboken, New Jersey and followed the rules that the New York Knickerbockers had developed. Alexander Cartwright, also known as the father of baseball, was the umpire in this first baseball game. He was also the founder of the Knickerbockers team, which is considered one of the first baseball teams who played under rules similar to today.  The National Association of Baseball players were established 10 year later.
