I read the Athletic article and a similar result happened in low A ball with the robot umps. This is the place to start the process - the zone needs to be expanded, but eventually (2-3 years) the accuracy will surpass the human angle. I am tired of the constant questioning and arguing with the umpires - most are really trying and doing the best they can.
The pitch clock has been a big positive in the minors (and the olympics). 15 secs is way too fast, probably start at 20 or 22 with no runners on base and then add the clock with runners on base in year two. I am all about limiting pick off attempts too - Greg Maddux always said just worry about the batter. And if steals go up, walks should go down with the base stealers.
I do agree the ball needs to be deadened some more. HR's are down this year, but hitters are still trying to hit HR's vs put the ball in play. Play-off games are too long! My son and his friends barely watch - college age.
