Casto Coming North?

From Barry:

Casto has options remaining, so unlike Church and Snelling, he could be sent to the minors without risk of losing him to another team. But there are indications that the Nationals are at least considering taking an 11-man pitching staff to start the season in order to make room for Casto.

I'm not holding my breath, but it'd be interesting. Even if they back down from Church, Snelling would deserve the LF job. Then the only position for regular ABs is first, and the thought of Dmitri Young there makes Jim Bowden tingle. So where would he play?
