The 1985 American League Championship Series was played between the Kansas City Royals and the Toronto Blue Jays from October 8 to October 16. Major League Baseball decided to extend the Championship Series in both leagues to a best-of-seven format starting with this year, and it proved pivotal in the outcome of the ALCS. The Blue Jays seemingly put a stranglehold on the Series, going out to a 3 games to 1 lead over the Royals at one point.
