MLBPA’s latest proposal went over like a lead balloon, with MLB saying in some areas went backwards, a point that was strenuously denied by the Players Association. In the MLBPA’s proposal was allowing the league to make rules changes as early as the 2023 season, specifically: the ability for the commissioner to put in a pitch clock, larger bases, and restrictions on the shift.
Note: Do not believe reports that the players “agreed” to anything. No one thing is agreed upon until the whole package is agreed upon. A good thread from Eugene Freedman on the subject.
