Almost every MLB team will look to the free-agent market this winter as they try to improve their chances in 2013. If they cannot find the players that they want there, then the trade market will also provide them with another way to fill their needs.
A number of top players could be on the trade market this winter and it would not be surprising if at least a few of them found themselves on the move.
Some teams are building for the future and will look to get young prospects back if they trade their young stars. Other teams may look to trade one talented player for another that better fits their needs.
