It's that time of year again, when MLB teams begin to separate into buyers and sellers.
The buyers, looking to improve their chances at making the playoffs, will be trading from areas of strength to add key players down the stretch.
The sellers, for the most part, are looking for prospects as they move high-priced veterans and free agents to be.
As in any year, a handful of players will be at the center of the drama surrounding the July 31st trade deadline.
Relief pitching always seems to be a vital need this time of year, and San Diego's Heath Bell is perhaps the most sought-after player on the 2011 trading block. A premier closer, he has the stuff to instantly improve any bullpen.
But Bell is hardly the only name being discussed in baseball boardrooms around the nation. He headlines a list with a dozen more players who will be at the heart of offers made and received this July.
