T-Ball...

I have had "plenty" of games utilizing both T-ball and "coach's" pitch, and I have never stood behind the pitcher, or the circle. It should not matter what level you are umpiring, you should always be in the standard position for plate umpires. I feel that by staying in this position, I still have the whole field in front of me (not to mention anything I may miss from 30-plus feet away, i.e. catcher's obstruction, etc).

I also realize the leagues may not call balls and strikes, but at least I can still practice my strike zone (even if it's just in my head). But if you do call balls and strikes, then calling them from behind the pitcher makes it no different than when you call it from behind the plate and a ballplayer 40' away saw something different.

JMHO,
