Busy day with the Washington Nationals.

Ryan Zimmerman returns after a stint on the DL. While nobody is expecting a Nats run at the playoffs, this should help the team get on track and put together a decent run in preparation for next season.

Next, Jon Rauch gets traded to the Arizona Diamondbacks in exchange for second baseman Emilio Bonifacio. Bonifacio has been designated the Nats 2B of the future and will spend time at AAA Columbus until then. Obviously this puts pressure on Felipe Lopez to keep his job.

Finally, Cristian Guzman signs a new contract with the Nats. This event alone does not really mean much itself, except that the Nats are assured that shortstop will not be on their shopping list for next season. However, in combination with Zimmerman, and the Lopez/Bonifacio 2B, most of the infield is set. All we need is Nick Johnson to stay healthy for longer than a week or Dmitri Young to step up his defense, and the Nats have a pretty solid overall infield.
