To tell you the truth I haven't had ANYONE run onto the field since my first year umpiring for this area SIX years ago. That gentelman was a personal friend of mine and he was quickly and firmly kicked to the curb. After coaches saw that I would do this to someone that was my friend they never even tried to cross that line.
At my plate meeting I always tell the coaches if they have a question to call time and come out and DISCUSS it with me.Yelling and screaming I won't put up with ,it's demeaning to ME the GAME and it shows the kids the wrong kind of behavior. I have not had one problem in the last six years with this area.
