MLB, as expected, imposed a schedule of 60 games to begin on or around July 24th. If the PA signs off on a couple of points (health and safety protocols for one) then the players will report to their home stadiums on July 1st.
The whole thing could still be scuttled if the COVID-19 infections continue to increase. Brewers pitcher Brett Anderson tweeted "What happens when we all get it?"
This whole thing has been a bad time for baseball. They might have been smarter to simply cancel the season from the get-go and then spend the time carving out a new agreement.
