MLB and MiLB teams typically have their own separate seasons, but the two leagues may collide against one another as early as 2021.
In Major League Baseball’s most recent proposal to Minor League Baseball’s negotiating committee, JJ Cooper of Baseball America reported on a potential single elimination tournament known as “The Baseball Cup” that would put 30 MLB teams up against 120 minor league affiliates during the regular season.
This proposal would essentially have the Arizona Diamondbacks face a minor league team and vise vera, a D-backs’ minor league affiliate could play against a MLB team.
