Major League Baseball tweaked its labor offer to the players on Monday, but the two sides remain far apart on a new collective bargaining agreement, according to sources.

The two sides spent five hours in Jupiter, Florida -- sometimes together, sometimes talking separately.

The league increased its commitment in a pre-arbitration pool to $20 million -- an increase of $5 million since its last offer -- while adding another team to the lottery in its new NBA-style draft proposal.

MLB also withdrew its request of the union to control -- and potentially reduce -- the number of minor league playing jobs.
