Pulled from an online blog of some sort:
In this day and age, one thing in baseball is even rarer than an unassisted triple play - a year where only one new stadium is opening. But in 2008, only the Nationals will have a new home. While the Nats hardly have any stud players (Ryan Zimmerman will make many fantasy rosters), it’s useful to know how the ballpark will play for the sake of estimating 2008’s numbers.
The dimensions: 336-L, 377-LC, 403-C, 370-RC, 335-R
Comparing those dimensions to other ballparks is a good way to see how they’ll play out.
Overall, the most similar ballpark to the new Nationals Park is Busch Stadium. There are only slight differences in the dimensions: Busch is two feet shorter in left center, three feet shorter in center and five feet deeper in right center. The corners are identical. Busch Stadium is a pitcher’s park, with a park factor of 0.933 and a home run factor of 0.717.
Arguably, power alleys are more important than corners and dead center. In terms of power alleys, Nationals Park is most similar to Great American Ballpark (which is two feet deeper in left center) and US Cellular Field (which is two feet deeper in right center). Great American is one of the game’s top hitter’s parks, with a park factor of 1.034 and a home run factor of 1.418, the highest in baseball. US Cellular is also a hitter’s park. It has a park factor of 1.084 and a home run factor of 1.220.
Nationals Park has shallow power alleys and relatively deep corners. That’s going to play out very well for the offense. It will mean a lot of home runs to the alleys and a lot of extra base hits down the lines. Great news for Nationals hitters, bad news for their pitchers.
