The Nationals won't release their 2011 spring training schedule for a while yet, but thanks to a few teams that have already put theirs out, we can piece together a few games of it.
Here's what we know so far:
March 3: at St. Louis (Jupiter)
March 17: at Atlanta (Disney)
March 18: vs. St. Louis (Viera)
March 21: at. St. Louis (Jupiter)
March 25: vs. St. Louis (Viera)
March 28: at Atlanta (Disney)
I'd guess that game against the Braves on the 28th could be the final game the Nationals play in Florida, before opening the season at Nationals Park on March 31.
