I don’t really care how the umps feel. If I were commissioner I would have ABS call all balls and strikes and the home plate umpire would function more like the other base umpires. Why not use available technology to make the correct call on every pitch?
I go to a lot of minor league games and watched all the experimentation with ABS under a variety of scenarios, to settle challenges, to call all pitches, etc. and the system works great. Some folks are worried about challenges slowing down the game. Fine, then use ABS on every pitch and do away with those challenges. Pitchers hate my idea because they depend on fooling the umpire as well as the batter. They depend on those expanded strike zones from the umpires and catchers framing their pitches, ABS eliminates all that subjectivity.
