The trade rumors regarding Adam Dunn are beginning to heat up.

Although Washington Nationals’ general manager Mike Rizzo has steadfastly claimed that he will only trade Dunn if he receives the most exceptional of offers, ESPN’s Buster Olney reports that Dunn is beginning to grow frustrated with the pace of negotiations on a contract extension.

Further, as the Nationals fall further and further behind in the NL East—they’re currently 13.5 games back—buying is no longer an option, and refusing to sell a player who will become an A-list free agent at the end of the season may be foolish.

If I may editorialize for a moment, as a Phillies’ fan I would love to see Dunn go, but as a baseball fan, I am excited about Washington’s potential in the coming years with a Zimmerman-Dunn-Willingham-Harper nucleus and a Strasburg-Whomever-Whomever rotation.

Nevertheless, here is a look at the top six landing spots for Adam Dunn in 2010, should the Nationals decide to trade him.
