Buried in this New York Post article by Joel Sherman from a couple of weeks ago detailing some of the disagreements between players and owners is this nugget about how MLB team rosters might be constructed in an abbreviated 2020 season:
The current plan calls for either 78 or 82 games, regional play by which teams play exclusively in their division and their crossover division (thus, AL East vs. NL East) to limit travel and both the rosters and the playoffs are expanded — I heard a strong possibility of 30 players available daily with a 20-player taxi squad staying ready if needed and a postseason of 14 teams rather than 10.
