Somehow this news slipped right on past me, and others it would seem. Evan Drellich of The Athletic wrote about it this morning, noting that Rob Manfred told Brian Kenny at MLB Network during MLB Now last week that “It’s why we’re using it (the automated strikezone) in Minor League Baseball next year, in some ballparks at least. ”

Minor League Baseball is and always has been a testing ground for rule changes that Major League Baseball is considering using in the future. In the last few years they’ve adopted the “runner starts on second base in extra-innings” rule to try and keep games from going 19 innings. They’ve also adopted the pitch clock, attempting to speed up the games with regards to pitchers taking too long between pitches.

This past year Major League Baseball went to The Atlantic League to test out a few new things. One of them was to use Trackman to call the strikezone rather than human umpires. Opinions were split on how that went. The powers that be then put it in place at Salt River Fields in the Arizona Fall League. With two teams sharing the complex this year, there was an automated strikezone for more than a few games out there this season, too.

From the article by Drellich, the plan remains a bit unclear. Which leagues will be used doesn’t seem to have been decided. It also hasn’t been decided on what system would be used to call the balls and strikes. Both are important to the conversation, but it’s the latter one that is far more important in my opinion.

Currently all of the testing has been done by utilizing the existing Trackman systems – both in the Arizona Fall League and in The Atlantic League. Trackman is the same system that’s used in the Major Leagues that tracks the pitches/hits you see on Gameday or your television screen. There are some issues with it and what it’s spitting out. It, just like the umpires, aren’t perfect. It should, however, be consistent on a given day – at least when it comes to the edges of the plate. The top and bottom of the zone, there’s plenty to be figured out there since it changes with every single batter.

That, though, is less of an issue for me. The larger issue is two-fold. First, all of this testing that has been done has been done via Trackman. The issue is that Trackman will not be used in Major League Baseball beginning next year. They are moving to the Hawk-Eye system that’s used in tennis and cricket around the world. Currently the minor leagues have Trackman installed at every park. Continuing to use that to test things out seems a bit strange because you can’t exactly work out the kinks for the Major Leagues by using an entirely different system.

Drellich reached out to the Commissioners office about the system that would be used and there was no comment. As I wrote about back in May when the story came out about the switch to Hawk-Eye, Trackman is going to remain in the minors for now. But teams are also considering Hawk-Eye in the minors, too. Perhaps the league where this will be tested out in 2020 would be done using Hawk-Eye that will need to be installed league wide.

The other issue that comes into play here for me is the way this messes with development. It feels apparent that the automated strikezone isn’t coming to every league in the minors in 2020. If that’s the case, then the players going through the leagues that do have it are going to be facing a different kind of development than those who don’t. Pitchers will have a different working strikezone in a league that they didn’t below or above it. The same goes for hitters. What is a strike on June 19th in the Florida State League is no longer a strike on June 21st when that player is promoted to the Texas League.

Being able to understand the strikezone is very important to development. And having different rules in different leagues can really throw a wrench into that. This isn’t like a pitch clock, or even starting a runner on second base. Those don’t fundamentally change the way in which you play the game. Changing the strikezone absolutely does. And when it’s different from level to level, that is a real problem.

This story, of course, is still developing. Major League Baseball is being rather quiet on a lot of fronts with this one. Plenty of things need to be hammered out – but for now, this seems like a poorly thought out plan. And honestly, that shouldn’t surprise anyone given that it’s a plan being implemented by Major League Baseball.

    Very understandable objections, particularly the up/down – i.e. Altuve – vis – Judge, crouching/upright stances. But, maybe someone (i know, don’t presume MLB) has determined that the differences between the systems are equal to or less than the differences between individual human umps, or even zones called in different leagues or levels?

    Still, the up/down issue does seem immediate.

    An automated strike zone is definitely a step in the right direction but even improving the balls and strikes isn’t going to save MLB after the players led work stoppage that we will see in 2021. Apparently 2 to 300 hundred million-dollar player contracts aren’t apparently enough.

      Revenues are going up. Spending is going down. The players should be very upset about this. Sorry that you think the billionaire owners should be hoarding even more of their money.

        Not saying its right but the players are equally greedy. A max cap is needed because like it or not thats the reason why minor leaguers pay sucks…. its the mlbpa keeping them from sharing the pie.

      • Doug Gray

        Minor league pay sucks because the owners can get away with not paying them. They could easily pay them more if they wanted to. Or if they had to.

    League to league variability is a lot more consistent than umpire to umpire variability, or inning to inning variability, or half inning to half inning variability, which is what we have now. Just removing Angel Hernandez from calling balls and strikes is worth it.

    Went to Atlantic League game this summer and could not tell the difference other than less complaints.

    I hate that they are removing all arguments from the field. I for one have found them to be entertaining.

    It seems like there could be a way to have the system immediately tell if it is a strike based on crossing the plate and let the home plate ump determine high or low. It seems the human misses are much more on the outside/inside determination.
