Jordan Zimmermann said contract talks with the Nationals are "kind of hung up right now."

Zimmermann requested $5.8 million and was offered $4.6 million by the Nationals when arbitration figures were exchanged earlier this month, and it sounds like the two sides are having trouble closing the gap. The Nats and Zimmermann have expressed interest in a long-term extension, but that doesn't appear terribly likely at the moment.
