According to Bill Ladson at MLB.com the Nats have agreed to sign Adam Kennedy. Fangraphs has CHONE and fan projections suggesting he'll be worth about one run above replacement, and about 3.5-4.5 million dollars. Even at that modest rate of production he would still about 3 or 4 wins better than the Nats' second basemen last year (assuming he plays every game). He'd be something like one or two wins worse than Orlando Hudson. But he should be a lot cheaper and is still an upgrade.
Another move to be quietly contented with from Mike Rizzo.
