The MLB Players Association is preparing its response to the proposal made by Major League Baseball last week, tweets Jon Heyman of the MLB Network. Heyman adds that the union is expected to put its next offer on the table within a matter of days.

The league broached some features of core economics last Thursday, marking the first instance of discussion between the two sides on any especially contentious issues since MLB instituted a lockout on December 2. The league’s offer didn’t address all the most pertinent issues, though, with no mention of free agency eligibility or the competitive balance tax. Instead, MLB’s proposal focused on such topics as the draft order, arbitration, possible solutions to service time manipulation and playoff expansion, among others.
