1924 – The two leagues agree on a permanent rotation for World Series play proposed by Charles Ebbets: the first two games at one league’s park, the next three at the other league’s park, and the last two if needed back at the first league’s park, with openers to alternate between leagues. Next year’s World Series will commence at the National League city.
