Hi guys. long time viewer- first time poster. In my Softball Canada rulebook ther'es a diagram of the batters box showing that its 10 feet deep starting from the back lines of the batters box, and 8 feet 5 inches wide (2 batters boxes, 2 six inch spaces and 1 plate). We have a rule similar to the one stated earlier. Ours defines the catchers box as "that area within which the catcher must remain until the pitch is released. The lines are to be considered within the catchers box."
If the catcher starts outside the lines ( my front line is 10 ft from the back one)

I hold up the pitcher, reposition the catcher and away we go. If the catcher refuses to comply the pitch will be illegal.
I'm surprised that your interpretation differs from ours on this- usually we're very similar

Or do the other Canadian blue think I'm out to lunch?
