(Undated)  --  Commissioner Rob Manfred and MLB attorneys plan to present an economic plan to the union by tomorrow, USA Today reports.  The owners reportedly want a 50-50 revenue split with the players if games are played with no fans.  The Players Association can spend the Memorial Day weekend mulling the offer to strategize a counter-proposal.  The blueprint is to have the teams return by mid-June to resume spring training and start the season in early July.
