Obstruction or unsportsmanlike conduct.

Mark,

I cannot answer for NFHS, or for that matter, any other organization, as USC is basically a judgment by the umpire.

In my judgment, hollering at the opponent is USC. But that doesn't mean I go around tossing all the players. I just hold up the game until it stops.

Now, let me see, how long does the pitcher have before I can call a ball? d:-)
