Why two different baseballs AA below AAA/Major
I have asked this question on another forum with no answer to question -
I am curious why there are different baseballs used for AA and below and AAA/Major Leagues? If the answer is cost - it seems to me Major League baseball would find it cheaper to just buy more baseballs in bulk than to place two different orders for different baseballs?
I gather there is an obvious reason but I don't know it. Thanks.
