Worst Feeling
Umpiring is a tough job, especially behind the plate. Keeping your concentration for 250-300 pitches a game is very difficult. As chronicled in prior blog pieces, I’ve been in those umpiring cleats. Sometimes, you just miss a pitch. And when you do, you know! You can see it in the reaction of the players and coaches. Believe me, you know. It’s one of the worst feelings in the world. For the first time in MLB history, umpires now have some added corrective lenses in the automatic balls strikes (ABS) system. Just a couple weeks into the season, it’s clear that ABS is here to stay.
MLB and the Major League Baseball Umpires Association have always seemed to resist video review of calls on the field. Indeed, the NFL, NBA, and NHL all had some sort of review system in place before MLB developed instant replay during the 2008 season. Beginning that season, only the umpire crew chief could initiate a review. The umpiring crew would huddle on the field, review a video feed, and then decide whether to uphold a call. Of course, it wasn’t just any call. Only home run calls could be reviewed.
It wasn’t until 2014 when the current replay system was instituted to include more than just home run calls. Managers are given one challenge a game (which you do maintain if you are correct) on a wide variety of plays (fair/foul calls, tag plays, catch/trap calls, etc.). From the eighth inning on, the umpire crew chief can also initiate a review. With the expansion of the replay system, baseball fans and commentators began to offer criticism on which plays are reviewable and how much time it takes to make a review decision. In addition, in view of today’s HD television and the imaged strike zone, umpire performance has been scrutinized more and more each season.
TrackMan, a radar-based system to call balls and strikes, came onto the baseball scene less than ten years ago. In 2019 the Atlantic League tested the technology for its college player summer league. While the new system had some mixed reaction early in the season, it seemed to gain favor as the season wore on. Later that year, the Arizona Fall League adopted TrackMan with even greater success. ESPN baseball insider Buster Olney opined that technology would replace home plate umpires calling balls and strikes by 2023.
Over the past few seasons minor league baseball has experimented with the ABS system. ABS does not utilize robot umpires, as Olney predicted and others feared, but rather technology to assist umpires in calling balls and strikes. TrackMan’s radar tracking has been replaced by camera-based tracking, called Hawk-Eye. Hawk-Eye has been found to be more accurate for determining the strike zone. High-resolution cameras are mounted in 12 different locations in each ballpark. During spring training play last year, MLB used the new technology at a handful of Cactus and Grapefruit League ballparks.
ABS will be in place for the entire MLB 2026 season. The system sets up a strike zone box for each player based on a natural batting stance. So if you crouch as a batter, it’s to your detriment. Each team gets two challenges that are triggered by a touch of the head by the batter, catcher, or pitcher. If your challenge is correct, you maintain it. What we see in the early days of ABS is that managers are allowing catchers and batters to use the system, but not often pitchers. We also see a trend developing that teams are saving their challenges for the later innings to make sure they are available when the game is on the line. One important feature stands out – the calls are made in a timely fashion.
So how have the teams been faring with the challenges? The early numbers suggest an overall MLB success rate of 55.9% (based on the 542 challenges made in the first two weeks of the season). Fielding teams are winning 59.7% of the challenges, while batters are winning 49.8%. There have been only 13 challenges by pitchers, six successful. If you are a fan of the Tigers, you have to be pleased with ABS since Detroit is winning challenges at the highest rate of any team (75%), followed by the Diamondbacks (71%) and the Orioles and Reds (both at 67%).
Home plate umpire accountability is at the heart of the matter going forward. Last season, without ABS, analysts determined a 94.2% accuracy rate on balls and strikes for MLB home plate umpires. With 100% accuracy seemingly now in play, some umpires are feeling the heat. Maybe ABS outcomes will influence fall playoff assignments for umpires. It’s hard to know at this point.
By an assortment of standards – fairness, accuracy, timeliness – ABS is a big success. MLB has to be especially pleased with fan reception. The reaction in the ballpark when the video board shows whether the pitch is in the zone or not has brought a new dimension to fan attendance. Unfortunately, home plate umpires have taken the brunt of the novelty of the new system. Since some umpires are getting more calls overturned than others, they indeed must be having the worst feeling of all.
Until next Monday,
