The Nationals are fielding a lot of calls from other teams about Adam Dunn, but have rebuffed them so far because they would like to keep Dunn in D.C. However, it appears they might consider moving him if they cannot agree to a long-term extension with Dunn before July 31, according to ESPN's Buster Olney.
Heard this: The Nationals may attempt to complete talks with Adam Dunn in the next eight days, and if they can't do it, they'll move him.
Keep in mind that, as Chris Needham notes, the Nationals can still get compensation in the form of two draft picks if Dunn leaves as a free agent this summer.
