Major League Baseball of MLB Baseball began in 1903 with a gentlemen's challenge. The two Major Leagues were an established one called the "National" and a newcomer called the "American." The owners of Pittsburgh's NL club and Boston's AL club agreed to schedule a series of games to decide true superiority of the game of baseball. This is one of the United States most popular sport. It can be found in countries like Cuba, Puerto Rico, Japan, and China just to name a few. Most cultures have some sort of stick and ball game, cricket being the most well-known. While the exact origins of baseball are unknown, most historians agree that it is based on the English game of rounders. It began to become quote popular in this country in the early 19th century, and many sources report the growing popularity of a game called "townball", "base", or "baseball". The first recorded baseball contest took place a year later, in 1846. Cartwright's Knickerbockers lost to the New York Baseball Club in a game at the Elysian Fields, in Hoboken, New Jersey. These amateur games became more frequent and more popular. In 1857, a convention of amateur teams was called to discuss rules and other issues. Twenty five teams from the northeast sent delegates. The following year, they formed the National Association of Base Ball Players, the first organized baseball league. Some of the greatest baseball player of all time is Babe Ruth, Willie Mays, and Barry Bonds. During the summer fans spend hours baking in the hot sun waiting to catch a foul ball while cheering for their favorite team.
