At least 30 days if they play all double headers (MLBPA opposed this) and there are no travel days, but more likely 75-85 depending on travel. A 60-game schedule would be 20 3-game series for each team. Ideally, each team would play at their home park 10 series and away 10 series for balance. Given the clusterfuck in Florida, Texas, Arizona, Georgia, and most of the South and West, I highly doubt a third of the teams can reasonably play at home much, if at all.
If a=2, b=2a^2+5, and c=a^3+3b^2+(2a-5b)/3, what is your favorite color?
