The origins(起源) of baseball probably stretch back to 1839 when Abner Doubleday, a civil engineering student, laid out a diamond-shaped field at Cooperstown, New York, and attempted to standardize(使标准化) the rules governing the playing of such games as town ball and four old cat, the ancestors(祖先) of baseball. By the end of the Civil War, interest in the game had grown rapidly. Over 200 teams or clubs existed, some of which toured the country playing rivals; they belonged to a national association of "Baseball Players" that had proclaimed(宣布) a set of standard rules. These teams were amateurs(业余爱好者) or semi-professionals, but as the game waxed in popularity, it offered opportunities for profit, and the first professional team, the Cincinnati Red Stockings, appeared in 1869. Other cities soon fielded professional teams, and in 1876 the present National League was organized chiefly by Albert Spalding. Soon a rival league appeared, the American Association. Competition between the two was intense, and in 1883 they played a post-season(季后赛) contest, the first "world's series". The American Association eventually collapsed, but in 1900 the American League was organized.
