Just for fun I thought I'd put together a proposal for a schedule for a shortened season. The scenario I went with was starting the season on July 6. I picked this date fairly arbitrarily, but it seems like a decently realistic scenario. Let me know what your proposed schedule would look like for that start date. Or pick your own scenario and try to put together a schedule. Here's mine:
To limit travel, teams will be reorganized into six geographically-based divisions, and to limit exposure teams will play only within their divisions. Here are the divisions:
All series are six-game series, plus a travel day after each series. So each series plus travel day, takes one week. Divisions of five also mean each team will get a week off every fifth week. Each team will play a home-and-home against each other team in the division, one series at each location. This totals eight series, or 48 games. Eight series is two cycles of one series against each of the other four teams plus an off week, so it will take 10 weeks total. With a start date of July 6 the season would end on September 12.
Rainouts would be made up as double-headers the next day, if there is a rainout of game 6 in a series, it will be made up as a noon game on the travel day. There will be one week between the end of the regular season and the start of the playoffs to make up any games not made up during the season, but only if they are necessary to determine a division winner or wildcard. Then division winner ties will be broken first by head-to-head record, then by run differential in head-to-head games, then run differential in all games, and finally by a tiebreaker game. Wildcard ties will be broken by run differential in all games, then by a tiebreaker game.
There would then be an 8-team playoff consisting of the 6 division winners plus 2 wildcards, which would be the top two second-place teams. Division winners would be seeded by record, and then the wildcards would be the 7 and 8 seeds, by record. Seeding ties will broken by run differential in all games, then by coin flip. All rounds are best of 7 in a traditional 2-3-2 format. Round one of the playoffs runs September 21 - 30. Round two runs October 1 - 10, and the World Series runs October 11 - 20.
A couple issues with this proposal are that it means one team from each division will start the season a week later, and one team from each division will end the season a week sooner. Also, run differential could get skewed by weaker/stronger divisions, but I used that to avoid having to play as many extra games as possible.
