Here's a final flurry of news before everyone bolts from Nashville:

The Nats have signed Aaron Boone to a one-year, $1 million contract, with incentives. Boone, of course, has a lengthy history in the majors and is the son of Washington assistant GM Bob Boone.

Wily Mo Pena has agreed to a one-year contract with a one-year option. Pena, who was arbitration eligible and would have been a free agent after the 2008 season, gets $2 million in 08. One of two things can happen in 09: Either the Nats pick up a $5 million club option, or Pena picks up a $2 million player option. Either way, he's all but assured of being in a Nats uniform for the next two years (barring a trade or something crazy).

Ryan Langerhans also has avoided arbitration, agreeing to a contract that will pay him $500,000 if he's on the major-league roster, $300,000 if he's in the minors.
