In yet another counterproposal in the long and public talks between Major League Baseball players and owners, a 16-team playoff is now on the table. The Players’ Association submitted a plan late Tuesday that would include an 89-game season with a 100 percent prorated salary. That compares to the owners’ idea of paying 75 percent of regular wages. To sweeten the pot, the MLBPA is dangling an extended postseason that would include two additional teams in each league, expected to produce new revenue. The format would be used this season and next.
