44 years. 1956 Yanks over Dodgers.
I beg to differ with you…the 1956 Dodgers were from Brooklyn, not New York…the old Brooklyn Superbas left the American Association in 1889 (after losing the World Series to the New York Giants!) and jumped to the NL, thus winning pennants in two different leagues in successive years. And yes, I know that Brooklyn is on the New York subway system. (The subways were not built until long after the Superbas left the AA.)
When the NL opened for business in 1876, its charter included the rule that no city could have more than one team. When the Superbas joined the NL in 1890, they did not violate this rule; Brooklyn was not part of “New York City” and did not join NYC until the charter of “Greater New York” went into effect January 1, 1898, thus putting the Dodgers, or the Giants (in Manhattan), or both, in violation of the NL charter, a situation that existed until both teams left New York State after the 1957 World Series. (I noted a similar situation in post-World War II politics, wherein the USSR got three votes in the UN General Assembly because Byelorussia and the Ukraine were admitted as ostensibly separate countries.)
If Long Beach, CA, had an AL team, and they and the Dodgers were to win the pennants, would you call that a [Metro Rail] “Blue Line Series”?
