We still don’t know when the 2021 MLB season will begin. But at least we, now, know that they are discussing it. The two sides- the owners and the MLBPA- are said to be in negotiations for a 154-game season that would start a bit later than what is typical. The idea would be to start toward the end of April rather than closer to the start- or before- as we usually end up seeing.
Full salaries, based on a 162-game season are said to be included in the deal, though you’d have to imagine a lot of seven-inning doubleheaders will be played. Other things like the universal DH and an expanded postseason are also said to be on the table as part of the negotiations, but it’s hard to say what will ultimately be decided upon at what is a very early stage to these proceedings.
