Thanks Dad - yes I know the lines are within the box. But say a batter stands with his heels on the line and the rest of the foot clearly outside the box? Is that considered "within" the batters box? If no, why then if a batter swings, and his heel is on the line but the rest of the foot out is that legal? This is of some considerable debate in our association. It seems that one coach has taught his players to crowd the plate, so much so that only the heels are on the line. For a HS player with size 12 - 13 feet, the batter is clearly over the plate. To if 90% of the foot extends beyond the boundary of the lines on the batters box, is the batter really within the batters box?
