Well we do not have police protection for these games. We are lucky if there is any organized security at any baseball game.

If this was the case in my area, I would stop the game and not start the game until the individuals were removed. And when they are removed we would continue the game. The home management is often the home coach and they would either call the police or have school personnel take action (which means they would call the police if the fans did not leave).
