MLB Trade Rumors | Mark Polishuk: After receiving the union’s latest offer on Tuesday, the owners have opted not to counter-offer, putting a pause in negotiations after a recent spat of small progress. Instead, the league is looking for federal assistance in the form of a neutral mediator in order to get the two sides to start talking about bigger issues that have so far gone untouched. The other three major professional sports leagues have used federal mediators in the past decade with mixed results, and MLB attempted to use one back in the 1994 strike to no avail.
