Inconsistent is better than not having zone at all. If I have to chase a zone - while that is not ideal, at least we can try to work with that. We always are looking to find where the zone is and adjusting to how the game is being called.
If you NEVER raise your arm to make a called strike call then you shouldn't umpire. As simple as that. I can't 'find the umpires zone' if he doesn't have one.
Next time I get a "throw down the middle only at waist height or you have no chance of getting a strike" umpire I am going to take a tee out to the plate, put a ball at it and tell the umpire that I might as well just let them hit off a tee because that is what he is making my pitcher throw.
I'll get thrown out but at least I'll have earned it for once.
Yes, Yes, and YES!!!!!!!!!!!!
