Americans consider baseball as an American sport. They often refer to something being “as American as baseball and apple pie”. But is baseball really an American sport? And what are origins of baseball anyway?

The American game of baseball more than likely came from several European ball games. Russia had an early form of baseball and so did Germany and Romania. People in England played a game called “stool ball”. In this game, the pitcher(投手)tried to hit a stool(凳子)or chair with a ball and the batter(击球手)used a stick to keep the ball away. But American baseball was most likely based on another English game, which is called “rounders”. Players use a soft ball rater than a hard ball while playing rounders.

So when was the first real game of “baseball” played? It seems that it took place in the 1840s. The father of baseball was Alexander Cartwright, who organized a baseball club in New York. Cartwright developed 20 rules that distinguished baseball from previous ball games.

In 1858, the first organized baseball league—the National Association of Baseball players—was formed. This league began charging fans to watch the games. However, the players were all amateurs and did not get paid . In 1869, the Cincinnati Red Stockings began to pay their players. Since they could hire the best players, Cincinnati won 57 games and lost none in their first season. As a result, other teams decided to hire players too. By 1871, the National Association was the first professional baseball league.

Today baseball is liked very much in America. Top professional baseball players earn millions of dollars each year. There are two professional leagues—the National League and the American League. The best teams from these two leagues compete for the baseball championship every year.
