NASHVILLE – The A’s and White Sox continued discussing a Brett Lawrie trade Wednesday afternoon, but it doesn’t appear a sure thing that a deal gets done between the sides.

A prospective trade would send two minor leaguers back to Oakland in exchange for Lawrie, who could fill a need for Chicago at third base. The sticking point, a source told, is agreeing on who those prospects would be.

The A’s feel they’ve got one of the most versatile infielders available in Lawrie -- who turns just 26 in January and comes with two more years of team control -- and they want what they consider fair compensation. The Sox have balked at some of the players Oakland has requested, the source said.

It’s not out of the question the A’s could try to engage other teams in trade talks, though a general feeling remains that a deal with the Sox could come to fruition.

Were the A’s to trade Lawrie, they would likely plug in recently acquired Jed Lowrie at second base and keep Danny Valencia to play third.
