Jon Niese for Starlin Marte
While this trade is not the sexy splash we want as Mets fans, it would give us a LF bat we can slot in the leadoff spot. Niese's contract would be appealing to the small market Pirates and give them a reliable lefty that can fit into the middle of the rotation.
Getting rid of Niese can give us room to bring up some of our young arms. The Pirates can handle the loss of Marte with Josh Bell and Austin Meadows in the minors.
