slow pitch strike zone

[tzme415]

I do mainly SP, this is how I try to stay consistent.

1) Watch the ball from the pitcher's hand to its apex to determine if it was a legal pitch.
2) Only worry about the pitch being over the back shoulder when it crosses the plate - this is a ball; anything lower is a strike (If it doesn't cross the plate including hitting the plate then it is a ball of course).
3) Don't worry about the ball being lower than the front knee - although noone has proved it to me - it is accepted that if the pitch is legal and lands behind the plate that it has to have been at least knee high.

So I try to get my eyes even with the back shoulder of the batter.
