I have mixed feelings on robot umps. In many ways, reading the ump has been a big part of baseball for over a century. It's not that bad when they are consistent, but it's so painful to watch balls called strikes when it's a big moment. Infuriating really.
I hate the robot ump idea. Not the least because umpiring is a potential future path for women in the game. Plus there's a difference between the rule book and the way the game is actually played and I don't know what you do about that.
My issue is a few of the dinosaur prima donna umps that stick around. The game Angel Hernadez called last week was predictably dreadful.
