Interesting. I swear we've reviewed umpire stats in the past and they were a lot worse than that. This article says they were wrong over 12% of the time between 2008 and 2018.

I wonder if they've been getting better over the last few years?

If you click year by year, it does appears they're getting more accurate? This is such a hot topic that I'm not surprised. Gone are the days of just accepting the home plate umpire is a 'pitchers umpire' with this made up, ******** strike zone that he has a reputation of calling. I wonder as we continue to push those old dogs out of the game and replace them with umps who call the actual strike zone - and with more focus on a consistent strike zone game after game, if human umpires can continue to improve their accuracy to the point robo umpires aren't needed.
If there are on average about 300 pitches per game. If the accuracy gets up to 95%, that's only 15 'misses' per game. At that rate, I kind of doubt the changes we're suggesting robo-umps would create (can't throw as hard - need to throw more strikes) would actually happen...
