Batter hit by batted ball with both feet inside the batters box.

Question
QUESTION: As long as I can remember, and I'll soon, god willing be turning 61, this play has always been called a foul ball. Well, a coach in his first year of Kid's pitch, questioned the call of a fellow umpire on that situation. The coach noted that the front end of the batter's box is in fair territory and that's where the batter was hit by the batted ball, so he should be out. The coach, who appears to be well off, he had not one, not two, but five legal interns in his office research this situation and found nothing. Several fellow experienced umpires, including myself, researched it and we could not find anywhere an OBR that specifically states that if a batter is hit by a batted ball inside the batter's box, the ball is foul. We satisfied the coach by inference, using the definition of a foul ball, and the fact that the batter did not hit the ball with one one foot out of the batter's box, thus he's not out...etc,...but the question still lingers. Is there a reference that I can look-up and quote my fellow umpires and ultimately, satisfy the coach, where this situation is officially addressed? Thanks, J.R. Montes, WHUA, West Houston Umpires Association, Houston Texas. Look forward to your reply.

ANSWER: Jose,

I'll have to study more in OBR, but I found it in NFHS:

7-2-1f: A strike is charged to the batter when: a batted ball contacts the batter in the batter's box (foul ball).

I'll let you know when I find it in OBR.

QUESTION: I have heard from other experience umpires that the offensive team by their cannot force a pitcher to balk. For, instance the batter stepping out of the batter's box w/o being granted time while the pitcher is in his motion to the plate. The pitcher sees the batter stepping out of the box and stops. He did not deceive any runners which is the spirit of the rule, but nevertheless balked by failing to deliver the pitch. Can you clarify this.  Is this a myth, is there something in writing that I could refer to in case it happens to me.

Answer
Jose,

The offense cannot purposely cause the pitcher to balk:

4.06a-3: No manager, player, substitute, coach, trainer or batboy shall at any time, whether from the bench, the coach抯 box or on the playing field, or elsewhere桟all 揟ime,?or employ any other word or phrase or commit any act while the ball is alive and in play for the obvious purpose of trying to make the pitcher commit a balk.

6.02b: The batter shall not leave his position in the batter抯 box after the pitcher comes to
Set Position, or starts his windup.
Comment: If after the pitcher starts his windup or comes to a 搒et position?with a runner on, he does not go through with his pitch because the batter has stepped out of the box, it shall not be called a balk. Both the pitcher and batter have violated a rule and the umpire shall call time and both the batter and pitcher start over from 搒cratch.?
