Regarding the electronic strike zone. It seems all broadcasts show some type of digital strike zone during the game. However, none of them seem to adjust the zone based on the size of the hitter - the zone appears to be the same sized box whether it's altuve or judge at the plate.
I saw a note mentioning Manfred said something about "electronic strikes zones were the future" and I started wondering if there would be a 1 size fits all zone or customized for each batter based on size, their stance, etc.
On a related note, there was a kid in the LLWS who was trying to draw a walk or something, so he stood at the plate crouched so low his butt was 2 inches off the ground. His head was 2 feet off the ground. Ump still called a regular strike zone as if the batter was standing normally. Was amusing and related to my question above.
