If baseball returns in 2020, the schedule is going to look a lot different than it does over a normal six-month season. Likely, there will be less days off, more double-headers, and a push to fit as many games as possible into a short timeframe.
It is expected that Major League Baseball will allow teams to expand their rosters to accommodate for a compressed season, as rest will be at a premium. To help compensate, teams will likely employ six or seven-man rotations to start the season, especially if a second Spring Training is abbreviated and pitchers need more time to stretch out their arms.
