I wouldn't consider it a pitch if it bounced off the backstop and hit the runner coming home.

Of course, if it bounced off the backstop and went into DBT, it would be considered a pitch.

I guess it would be treated as if it bounced off the catcher's mask. Straight off the catcher's mask into DBT, it's a pitch. Straight off the catcher's mask into a runner coming home, it's not a pitch.

Now I'll find out that this is covered in a case play and I'm wrong.
