thanks @Jack Parkman for making a thread for this. I saw allusions to this on twitter yesterday but didn't know the source of it.
Manfred's handling of this from the beginning, when he stated the balls from 2017(?) were not different when they had proven to be, to now this, is just such brutal incompetence.
Baseball fans care a lot about integrity of numbers. If a ball changes, a ball changes. Just be open about it. But to use different balls secretly is such garbage.
Also clearly Kimbrel kept being given the exploding baseballs.
