Albert Spalding,
America's National Game
(1911)
“ Had that ancient organization never encountered opposition, the chances are that there would never have developed a national game. And so it needed the American League, with the Boston Americans' victory of 1903, to make the National League managers realize that they had not all the ball players on earth—that there were others. And when the Chicago White Sox in 1906 again took the national pennant from the pioneer League, it served as nothing else could have done to stimulate interest in the sport in every quarter. ”
