I agree with no call on the shout from the stands, but would any of you consider some kind of preventative officiating by saying some type of general statement to the fans or even the coach or manager of the team to share with the fans? Something to the effect of "don't do that again"?

Since I do slow-pitch only, I would probably have a word with the manager/captain of both teams, asking them to let their fans know that shouting this kind of thing is not really appropriate, and to refrain from it. I don't know, but something tells me if this doesn't get nipped in the bud this time, someone is bound to have some serious problems down the road.
