Batter's Box question

[DG]

No matter how odd a play is, never say it will not happen again, because it will and next time you will have learned from the experience and have a better response.

No need for a verbal response, when calling a batted ball that is near a foul line FAIR, simply point toward the infield which should indicate to all that the ball is laying is a fair ball, if it was lying at rest in fair territory or picked up in fair territory by the catcher. When PU I use my left hand to do this, so the defense is not confused about what the call is which they might be if I brought my right hand up to point. This should give everyone the signal they need.
