Two years, $20 million, which is a bargain for a guy who'll hit a ton of home runs and net the Nats a couple of good draft picks when he hits a better free agent market. Nats GM Jim Bowden drafted Dunn as the GM of the Reds, and Dunn is also close with Nats outfielder Austin Kearns, so there's probably no way the Pirates were getting in on this action without spending significantly more money. Dunn will play first base for the Nationals, which should limit the amount of damage he'll do on defense. Nice move by Washington.
