Somebody, I think it was Joe Posnanski, had an interesting suggestion. If the pitch is an obvious ball or strike, like the one mentioned above, it would be relayed to the umpire electronically, so that there would be no egregious calls. Umpires would still be on their own when it comes to borderline calls.
That might seem somewhat counterintuitive, but I like the suggestion.
It's only a game. Not life and death. Part of the fun is screaming " Kill the ump." " Are you blind , Blue ? " " Get new glasses." Etc. And watching a Billy Martin kick dirt and yell at the ump until he was ejected. Remy and O'Brien don't help with their constant complaining about the strike zone. Use the robots to vacuum the dugout and clubhouse, not to call balls and strikes. If an umpire is clearly incompetent, he should be demoted to AAA. Try to relax and enjoy the games .
I still contend that the biggest problem is umpires missing the outside part of the plate. To me, that's an equipment issue. If they had the equipment from back in the 80's, they could stand directly behind the catcher and see the outside of the plate. Currently, they set up to the side (do to their reduced equipment) and can't see the outside part of the plate.

Ron Kulpa has actually already conceded that he should have called Conforto out on strikes.
