Adam Dunn signed a two-year deal with the Nationals last offseason, but it's clear that Washington wants him over the long-term. Dunn and the Nationals have opened talks about a contract extension that would reinforce the first baseman's prominent role in Washington. The slugger said on Friday that the extension is "something I want to do." Talks are still preliminary -- Dunn described them at "stage zero" -- but the mutual interest underscores the satisfaction on both sides.
