out of box bat contact
 

New topic instead of hijacking the other (When is a Batter out of the Box? ).
1 - swing not needed; just contact and
2 - the foot must be completely out, not just part of the foot.

Thanx for the note, CecilOne.

Perhaps my original statement was not clear. I was trying to compare the batter getting into the batter's box (legally) with the batter leaving the box after hitting the ball.

Speaking USA/ASA 7.3.A

Prior to the pitch, the batter must have both feet completely within the lines of the batter's box. The batter may touch the lines but no part of the foot may be outside the lines prior to the pitch.

And, my note regarding NCAA clarifications in the other thread also applies.

"Within" means completely within; the lines are part of "within", no part of the foot may be out. The batter must be within the batter's box at the time of the pitch.

"On" means any part of the foot is in contact with any part of the line. The batter may be on the line at the time of contact, and is not out.

"Out" means a foot (or other body part), or every part of that body part that is touching, is touching completely outside the line. If the batter's foot (the part that is in contact with the ground) is completely out of the box at the time of contact, the batter is out.
