Strike Zone for slow Pitch?

[dong]

I know that we will call strike when the ball pass in the strike zone.

But in my propos try make it easy to judment for call strike, because of ball will trow in trajector will difficual to call strike.

Easy way we will juded on where the ball drop, we will make the strike plate and put it on the ground, the ball touch any part of strike plate it's will be strike.

Ball can not trow at less high of the batter head high but the top of ball trow not limit.
