I believe the Mat was endorsed to help out with lower end SP, when it comes to A Grade the Mat is used very little. I think the big Advertsing Tournament that is run annually in Palm Springs uses it, but that is the only big Tournament to use such a concept. It is also used a lot in Canada so I am led to believe. We in the UK have never, and God willing, will never resort to such a rubbish idea.
The Strike Zone belongs to the Umpire, and as such, You can make the batters swing, it is amazing how big the Strike Zone is, when you want it to be.... Slowpitch is a Batting Game
