Umpires Observe Foul Ball, Decide It's A Fair Ball

What you are looking at here is Max Kepler of the Minnesota Twins fouling a pitch off not one but two of his legs. That is, by rule and interpretation of the MLB rulebook, a foul ball. Kepler was called out, 1-3, and the inning was ended.

The Twins’ announcing team was fairly aghast at the outcome, which, unlike nearly every other play that can happen on a baseball field, was not reviewable by replay. The Twins won anyway, so it didn’t matter. But still! (Normally we assign blame to an individual umpire in these circumstances; all four of them should have been capable of noting what happened here, but nobody did.)
