I have some idea
In my country in SP strike zone will be applied to use strike plate.
strike plate is a rubber plate cover on interval betaween batter box but short than batter box about 6 inc.
batter box is 7 feet long, 4 feet on front and 3 feet rear.
strike plate start from 3 feet rear include angle of home plate till last batter box but short than its 6 inc.
batter will still in batter box while batting ball
ball hit front home plate is not strike
ball hit any part of strike plate include angle of home plate it's will strike
runner take home can use both home plate and strike plate to avoid in the injurie case ( Catcher also )
