From SABR member Dan Glickman at Baseball Continuum on October 9, 2014:
Don’t believe the people who say that this ALCS is the first time that Baltimore and Kansas City’s baseball teams have met in the playoffs. It’s wrong.
Oh, to be sure, this is the first time the MLB franchises- the Royals and Orioles- have met. But it’s not the first time Kansas City and Baltimore have sent their nines against each other. It’s the second… and there could have been at least two more, had they been played. Using a few other resources, such as Baseball-Reference, SABR, and their joint wiki, here is the hidden history of Kansas City and Baltimore in the postseason.
