12/9/2020 : 2021 Minor League Structure

Updated: Dec 10, 2020

I can’t post the entire Baseball America article but here’s an excerpt explaining a little bit on how the 120 sites were chosen ...

“MLB reached out to hear from it’s 30 clubs who they wanted as affiliates, it quickly learned that for some it was important to have all four affiliates as close to the big league city as possible only for some teams. For others, that was not nearly as important. While few MLB teams got their full wishlist, MLB did not push too hard to get teams to drop current affiliates. As multiple MLB front office officials explained, there was a “if you want to keep your affiliate, you can keep it” rule that governed all of the moves.”


There are two AAA full season level leagues ... one in the Eastern US and one in the Western US. Here’s my guess at the alignment ...
