Hurrah! The first broadcasts of 2010 Nationals' games are made today. Even better, there's a choice of two games. At least that's what the MLB media centre tells me, as I find both the Marlins and Astros are listed as giving play-by-play of today's split squad games.
While you are waiting, here's a fun tool to play around with. It allows you to superimpose on any currently in-use ballpark of your choice the balls-in-play hit by a player or given up by a pitcher in a different 2009 ballpark. It's based on mlb.com's HitTracker, I think.
I've translated Jason Marquis from Coors Field to Nationals Park. I've limited my selection to extra-base hits and fly balls. Looks like he might give up a few more home runs.
