foot out of the box

[Dakota]

The umpire should make sure the batter is within the batter's box before the pitch. If the batter does not move when asked to do so, then the EFFECT can be used.

However, it is the batter's responsibility to be in the box. If the umpire does NOT make sure the batter is positioned within the box at the start of the pitch, and the batter hits the ball while one foot is completely out of the box or in contact with the plate, then the batter is out.
