I know this is a simple question, but I've gotten a lot of different answers to this question. Every diagram I've ever seen of the strike zone is a rectangle from the midpoint of the belt and armpits to the knees and the width of the plate. So I was wondering, is the strike zone a three dimensional "zone" the shape of the plate, or is it a rectangle at the front of the plate? A side arm curve could cut across the plate, but not touch the front of the plate. An Ephus pitch could fall into the zone at the back point of the plate, but be too high at the front of the plate.
Is the strike zone different for different rule sets (FED, OBR, LL, etc.)? Softball vs. Baseball? (I know unofficially it is, but I was wondering if the different rule sets actually defined the strike zone differently).
