The MLBPA delivered a proposal to MLB on Sunday afternoon, a source familiar with it tells ESPN. It includes 114-game season that would end October 31, the right to opt out of the season for all players and potential deferral of salaries if 2020 the postseason were canceled.

For the players opting out: those who are considered "high-risk" would receive salary, whereas others would receive service time only.

Further, players would receive $100 million total advance during the new spring training.

Also: MLBPA proposes two years of playoff expansion.

The inclusion of potential deferrals by players is an olive branch, even if it does apply just to a canceled postseason.

It would defer $100M total, applied to players making $10M+ before proration, and would do so with interest to make players whole. It opens the door to more.
