Baseball in the United States

The earliest known mention of baseball in the United States is a 1791 Pittsfield, Massachusetts bylaw banning the playing of the game within 80 yards of the town meeting house.

The first team to play baseball under modern rules were the Knickerbockers of New York City. The club was founded on September 23, 1845, as a social club for the upper middle classes, and was strictly amateur until its disbandment. The club members, led by Alexander Cartwright, formulated the "Knickerbocker Rules", which in large part deal with organizational matters but which also lay out rules for playing the game. One of the significant rules was the prohibition of "soaking" or "plugging" the runner; under older rules, a fielder could put a runner out by hitting the runner with the thrown ball. The Knickerbocker Rules required fielders to tag or force the runner, as is done today, and avoided a lot of the arguments and fistfights that resulted from the earlier practice.

Writing the rules didn't help the Knickerbockers in the first competitive game between two clubs under the new rules, played at Elysian Fields in Hoboken, New Jersey on June 19, 1846. The self-styled "New York Nine" humbled the Knickerbockers by a score of 23 to 1. Nevertheless, the Knickerbocker Rules were rapidly adopted by teams in the New York area and their version of baseball became known as the "New York Game" (as opposed to the "Massachusetts Game", played by clubs in the Boston area).

In 1857, sixteen New York area clubs, including the Knickerbockers, formed the National Association of Base Ball Players (NABBP). The NABBP was the first organization to govern the sport and to establish a championship. Aided by the Civil War, membership grew to almost 100 clubs by 1865 and to over 400 by 1867, including clubs from as far away as California. Beginning in 1869, the NABBP permitted professional play, addressing a growing practice that had not been permitted under its rules to that point. The first and most prominent professional club of the NABBP era was the Cincinnati Red Stockings.
