" Calling " Fair Ball

[DaveASA/FED]

Tony,
I would have stood there until it was obvious nobody knew what to do and then said something to the effect, "That's a live ball", "That's a good ball we need to do something!" This would get the point accross that there needs to be a play without the chance of Foul and Fair being confused, and also it is neutral to offense and defense (unlike, "You need to run" or "You better get the ball" etc). But that is JMO of what I would do.
