Why MLB's ABS Challenge System is Long Overdue

Welcome to 'Ask Jimmy,' where SI Media writer Jimmy Traina will answer one question about a burning topic from the sports media world.

Q. A balls and strikes challenge system is finally coming to Major League Baseball. After being used for several years in the minor leagues, the Automated Ball-Strike (ABS) Challenge System will be featured in the big leagues beginning next season. Each team will get two challenges per game when it comes to balls and strikes, which will be retained if successful. Are you in favor of this change?

This is nothing but a positive for the sport. You can’t have games decided on missed calls by the home plate umpire and this is a way to fix that.

The only downside is that I wish teams were allotted more than two challenges per game from the start. I’d give teams four or five challenges per game. Even if you think home plate umpires do a great job, they’re still going to miss a handful of calls in each game. Why not implement a system in order to rectify that?

If your argument against the ABS challenge system is that it will slow down the game, think again.

Baseball has done a great job of speeding up the game by instituting the pitch clock. The challenge system won’t have a significant effect on the length of games.

Via MLB: In 288 games with the ABS Challenge System during Spring Training 2025, there were an average of 4.1 challenges per game. Those challenges took an average of 13.8 seconds.

Adding on a minute to each game to get important calls correct is a no-brainer.

Baseball already has instant replay, so adding another layer to have balls and strikes challenged seems like a natural progression.

Think about how history would have changed if ABS was around in 1998 when the Yankees got this gift from the home plate umpire.

You just can’t miss a call like that in a World Series game.

The only downside in my view is that this will limit the number of player explosions when a home plate umpire gets a call wrong. Now, instead of throwing their helmet or slamming their bats, a batter will simply tap his head to call for replay.
