Robo-Umps Are Officially In Major League Baseball, and It’s An Ethical Development

Finally, Major League Baseball has conceded that with technology available to call balls and strikes accurately, it makes no sense to permit bad calls by human umpires to change the results of at-bats, games, careers and even whole seasons. In 2026 the “ABS” system will be in play, adding integrity, accuracy and, yes, strategy to the game. Good. It’s about time.

I’ve been advocating computerized ball and strike calls at least since 2017, when I wrote,

In the top of the eighth inning of a crucial Dodgers-Cubs NLDS game, Dodger batter Curtis Granderson struck out. The pitch hit the dirt, and Cubs catcher Willson Contreras, as the rules require when a strike isn’t caught cleanly, tagged Gunderson for the final out of the inning. Granderson argued to home plate umpire Jim Wolf that his bat had made slight contact with the ball. It didn’t. The replay showed that his bat missed the ball by at least four inches. Nonetheless Wolf, after conferring with the other umpires agreed that the ball was a foul tip. Gunderson’s at bat was still alive….

After the game, Wolf watched the video and told reporters that he had indeed, as everyone already knew, blown the call.

As it happened, his embarrassing and needless botch didn’t matter. Gunderson struck out anyway. That, however, is just moral luck. The call and the umpire’s refusal to reverse it was just as inexcusable whether it resulted in ten Dodger runs or nothing. The point is that such a call could have changed the game, and the series. If it had, the screams from Chicago fans and anyone who cares about the integrity of the game would have persisted and intensified until baseball abandoned its archaic rationalization that “human error is part of the baseball,” and made use of available technology to make sure such a fiasco can’t happen.

This scenario will occur. Human beings being what they are, however, it won’t play out until a championship has been lost after a strike three right down the middle of the plate is called a ball by a fallible human umpire, and then the lucky batter hits a game-winning, walk-off grand slam on the next pitch. Then, after the horse has not only fled but trampled the barn-owner’s children, Major League Baseball will put a lock on the door.

The barn door, however, is wide open now, and the lock is available.

Two years later, I complained about this foolish attitude by the baseball powers- that-be again, writing,

Moral Luck and Baseball: The High-Profile Ruinous Ball-Strike Call Comes AFTER The Problem Has Been Addressed


Next season, Major League Baseball will implement the Automated Ball-Strike (ABS) Challenge System. For the first time in regular-season history, batters, catchers and pitchers will have the right to challenge balls and strikes. Teams will begin each game with two available challenges and can continue challenging until they lose challenges twice.

The system has been desperately needed for many years, ever since each player’s strike zone could be seen on television screens during game broadcasts. As usual, baseball dragged its metaphorical feet addressing the problem, with the idiotic “bad calls by the umpire are part of the game” argument that traditionalists and ex-players are still using. That logic makes as much sense as defending medical malpractice because “everyone makes mistakes.” Sure, before video technology could prove a key ball or strike call was a bad one, tolerating home plate umpire mistakes (like the one that cost the Boston Red Sox Game 3 of the 1975 World Series and conceivably the Series itself) were part of the game, because nothing could be done about it. Now something can.
