I get that there are issues with the robo-umps and the definition of the strike zone (2D vs 3D measuring, matching top and bottom to actual batter stance, etc.). They just need to solve them because the moment they put the box on TV we got to see how many calls they actually missed. I just wish the AAA experiment this year had gone better since they keep changing the zone and fine-tuning the offensive explosion they unleashed.
I think I want the robo umps over the challenge system though I imagine we'll start with that.
