The question was, do you know the MLB rules for the 2021 season. Your answer is probably not. After reading this article, you will have some information but probably won’t know any more than you do now for what the rules ultimately will be for the season. The reason for that is the contentious relationship between the owners and the players. MLBPA, the MLB Players Association (players union), represents the hundred of MLB players. MLB represents the owners of the 30 MLB teams.
If you remember, before last season, the owners and players fought for weeks over the length of the season and the rules of play, along with what the health protocols would be.
