baseball

Americans began playing baseball on informal teams, using local rules, in the early 1800s. By the 1860s, the sport, unrivaled in popularity, was being described as America's "national pastime."
Alexander Joy Cartwright (1820-1892) of New York invented the modern baseball field in 1845. Alexander Cartwright and the members of his New York Knickerbocker Base Ball Club, devised the first rules and regulations for the modern game of baseball.
Baseball was based on the English game of rounders. Rounders become popular in the United States in the early 19th century, where the game was called "townball", "base", or "baseball". Cartwright formalized the modern rules of baseball.
The first recorded baseball game in 1846 when Alexander Cartwright's Knickerbockers lost to the New York Baseball Club. The game was held at the Elysian Fields, in Hoboken, New Jersey. In 1858, the National Association of Base Ball Players, the first organized baseball league was formed.
