A couple of tweets emanating from the Winter Class media room in Ann Arbor:
Nationals Park doesn’t have the history of previous Classic ballpark sites like Fenway and Wrigley, but Citizens Bank Park in Philly, host of the 2012 event, didn’t boast much history either. Opened in 2008, the home of MLB’s Nationals is a modern stadium with all the amenities, and the game will surely sell out quickly.
There’s also this, from the Washington Post in September:
…considering Nationals owner Mark Lerner is a minority partner in [Capitals owner Ted Leonsis’s] Monumental Sports and Entertainment, Nationals Park in Southeast Washington may be a likely candidate.
