Whether you like it or hate it, arguing with the ump over balls and strikes has been a part of baseball forever. Now, most of that joy or consternation is going away.

After years of experimentation in the minor leagues, Major League Baseball is set to unveil its ABS Challenge System with the start of spring training games tomorrow.

From now on, players will have the opportunity to appeal ball and strike calls from the human umpire behind home plate. The ABS system reads the exact location of each pitch, according to the unique strike zone of each batter. If the batter, pitcher, or catcher—not the manager—feels the umpire got it wrong, he taps the top of his head to challenge the call. Immediately, the pitch is replayed on the video scoreboard in the park, and to the viewers at home, showing the exact location of the pitch, determining if it was indeed a ball or a strike.

Theoretically, this will take only a brief moment. This system is a compromise between having the computer call every pitch, which is possible, and relying on the eyes of the human behind the plate for every single call, good or bad, which is how it’s been done for more than one hundred years.

Each team gets two challenges per game, which doesn’t seem like many. If they win the challenge, they retain that number of challenges they have left. In extra inning games, teams get one challenge per inning, even if they had exhausted their challenges during the first nine innings.

A few things to consider. Again, the challenge has to be immediate, without help from the dugout. That’s why only the pitcher, catcher, or batter can challenge, and not the manager or coaches. Since every pitcher who has ever thrown a pitch in any game at any level finds it totally unbelievable that there is any way they don’t throw strikes every singe pitch, most teams have already gone on record saying they will not allow a pitcher to challenge a call, only their catcher.

The umpire does have the ability to deny a challenge if he feels the player making the challenge was tipped off by anyone on their field, in the dugout, or in the stands. No banging trashcan lids. Also, if the team has a position player on the mound, the pitch cannot be challenged. And if there is a replay review of another play at the same time, an ABS challenge isn’t allowed, this is to prevent the game from being one challenge on top of another.

According to MLB.com, the challenge system doesn’t slow down the game much at all. The minor league gameplay data shows there were 4.1 challenges per game, each taking about thirteen seconds. So, the challenge system added about fifty-seven seconds to each game that has already been shortened an average of twenty-six minutes after the pitch clock.

The ABS system is designed to get calls right. Each pitch matters, especially in a tight game. Now that Angel Hernandez is not longer umpiring, calls are getting better but there are still umpires who struggle with the strike zone. Now players and fans don’t have to be subjected to chronically bad umps.
