Umpires Weigh in on New Automated Ball Strike Challenge System

No one enjoys being put on the spot at work, right? Especially when it’s in front of thousands of fans on a big screen.

Some MLB umpires are thinking quite seriously about the new Automated Ball Strike Challenge (ABS) system. They feel it sets a “nearly impossible standard” for their performance. It’s noted that the referees had agreed to this system during their last collective bargaining negotiations, which doesn’t exactly leave them options.

There’s been a lot of scrutiny on the ABS due to the perceived lack of accountability among referees. Both fans and players have expressed desire for fewer games influenced by sometimes questionable human judgment.

Interestingly, fans seem to appreciate the ABS approach, which offers batters a clearer view and rewards pitchers effectively.

Take for example those not-so-great games against the Yankees. Do you remember CB Buckner? He overturned six calls in one game, and Mike Estabrook had his own struggles, making five incorrect calls.

This new system was implemented to stop these types of calls from overshadowing the game.

One former player, Seth Lugo, shared an experience of a challenging game where there were 11 challenges, saying, “We all thought the referee was getting annoyed, but he actually said it was great since it improved his game.”

A significant issue with the ABS is the absence of a buffer zone. Even a slight miss—like 0.01 inch—won’t allow any leeway for umpires.

This means that a call considered a ball is treated as if it was entirely outside the designated zone.

Reportedly, umpires are frustrated that the ABS system isn’t foolproof. It’s been mentioned that there’s a 95% certainty that the ABS will pinpoint a pitch within 0.39 inches of its location. It gets a little wider with 99% confidence for the final landing location at 0.48 inches.

Umpires are wishing they could receive similar support, but it doesn’t seem to be on the table.

Michael Hill, a senior MLB executive, acknowledged the umpires’ commitment: “Major League umpires uphold the highest standards and strive for accurate calls. We value their professionalism and dedication to the game and our fans’ expectations.”

He also remarked on recent accuracy improvements, noting, “With a 93.5% accuracy rate this year, that’s a notable increase from the previous season.”

The Athletic pointed out that, while the top umpires averaged less than an inch in errors, Buckner’s average sat at 1.36 inches—far from ideal.

Then there’s Chris Bassitt, a right-hander for the Orioles, who came to the umpires’ defense. He said, “People don’t quite grasp just how close the pitches are to the plate. It’s easy to question a call, but really—when you look closely—it’s not as off as it seems.”

With the level of skill involved, he added, “Let’s not diminish the abilities of these umpires. They truly are remarkable.”
