Just for the sake of this thread's topic, suppose Robo Ump is completely off the table, for whatever reason. How do you improve the balls/strikes calling in MLB?
Have MLB use the grading system available to us online to evaluate umps when they are behind the plate.
Pay umpires a per game bonus when they are behind the plate.
Use the grading system to set thresholds on correct called balls/strikes that umpires have to achieve. If they fall below a certain level, they get penalized
First offense is a warning
Second offense they get skipped on the next rotation, missing out on the per game bonus
Third offense they miss out on home plate for a month
Just spitballing. How could they improve strike calling if the Robo Ump is a no go?
