The strike-zone is stable (for the batter size), the location is known. He can refer to that - with an audio command to recall, confirm or rescind his call.

of setting the upper and lower lines of the box. Is it a singular person that sets it, is it pre-set knowing the dimensions of each particular batter, or is it somehow automated, or something else I'm not thinking of?

Based on these 2 variables, that should provide all the customization the batter needs to get a fair strike zone. And Google Glass gives the ump the same visual we see from the centerfield camera....if we know it's a strike or ball based on the technology, the HP umpire should have the same info to get the call right.

The width of the strike zone is the width of home plate and never changes.

I'm easy.

No one ever admits to being wrong. You're supposed to call them a troll, question their motives, and call them a nasty name.

(for the record, taking the umps out of calling pitches makes sense to me too)

Me, I got corrected and educated at the same time. Learned something, I did not know.....BUT

All the more reason to make sure the strike zone is applied for everyone.

I was just making a (hopefully) humorous comment.

The bunch of us are colorful commentators.

The sooner the better. Truly it seems like in every single half-inning there will be a bad call or two. And that can make the difference between scoring runs or not. It's long overdue.
