I think MLB is testing robot umps in the minors

And you're right, balls and strikes have gotten so much worse the past few years.

But what happens with the home plate umpire if a robot takes over? Does he move to a new position somewhere else?

I guess he could still stay behind home for safe/out calls at the plate.

I'm all for it, though. I've seen too many games this year where a missed strike or ball creates a domino effect and impacts the outcome of the game.
