Second thing........ in baseball us catchers called the pitch by what the batter is doing in the batters box, or by his swng or weakness. In fastpitch the coach sitting way off to the side is calling pitches. How do they know what the batter is doing when they are way off to the side. The idea is to call different pitches to keep the batter guessing.
I think we tend to forget the idea of the batter and the batters box,,,,,,,,,,,,,,,,,,,, to keep the pitcher guessing. Thats why the box is 7 feet long. What pitch are the batters looking for its hard to tell when the coach called the pitch before the batter even got in the box. The batter should move around in the batters box, to keep the pitcher guessing,,,,, not just to move, but move and look for a certin pitch....just like the pitcher is moving the ball around to keep the batter guessing at what is coming.... The one that guesses right wins every time, guess wrong and you lose.
