On Sept. 17, 2019, the Sacramento River Cats beat the Columbus Clippers, 4-0. It was the last minor league game until the 2021 season begins, which is currently scheduled for May 4.
When minor league baseball does come back, it will be structured differently than it was when Sacramento won that game (Baseball America $). For the first month and a half, things will be relatively familiar, although many affiliates are different. It will be more noticeable come summer when short-season affiliates are mostly gone.
Those structural changes — and of course, the missed season — will result in significant changes to player development.
