So much about baseball in 2020 is uncertain. We don’t know when — or even if — a major-league season will begin.
It’s been widely assumed, if there is a MLB season, that teams will create 30-man rosters and 20-man “taxi squads” and that there likely won’t be a 2020 season for minor league clubs at all. One of the reasons for this is that unlike MLB, minor-league teams make virtually all their money from fans in the stands and games with fans aren’t likely to be approved in most jurisdictions in North America this summer.
