One of the greatest seasons in major league history ends with a blown call. Not a controversial call. Not on a play governed by an obscure rule. A blown call that will be revisited and discussed for years.

A strike is described in the rule book as “a legal pitch when so called by the umpire, which (a) Is struck at by the batter and is missed. ..."
