Dunn is in the last year of a two-year, $20 million contract with the Nationals, and he is looking to get a four-year deal.
"If we can't get something done, obviously, I would like to see what my option are," Dunn said to MLB.com. "I want to stay in one place. It's something I want to do. I never asked for anything like [a four-year deal] ever in my career. It's one thing that I want -- the longer-term contract. That's all I ask for."
Dunn is clearly one of Washington's best hitters, batting .271 with a team-leading 34 home runs and 91 RBIs entering Tuesday's action against the Mets. He also is considered one of the leaders in the clubhouse. Dunn is not afraid to tell a player when he is doing something wrong on the field.
General manager Mike Rizzo declined to talk about the contract negotiations with Dunn.
