Just as they did this spring, Major League owners and players are primed for conflict over the length of the upcoming season.

According to a report, owners want players to be vaccinated before spring training begins, which would mean a delay to the 2021 campaign.

That could mean Opening Day is pushed to May and a 140-game schedule is played.

The MLBPA does not agree with this timeline and is pressing to play a full 162-game slate.
