Early Returns on the New Parks

OK, it’s very early and the sample sizes are ridiculously small, so you’ll need to take this with boatloads of salt, but I ran some quick numbers on the new parks in San Diego and Philadelphia. Looks like most of the commentary about these parks is backed up by the facts; below is the average runs scored (by both a team and its opponents) per game:

Team Home   Away   Diff
SD    8.0   9.7    -20%
PHI   8.9   7.2    +24%

Like I said, it’s way too early to presume that Petco and the Cit will each affect scoring by 20% or more (though in opposite directions), but this should at least satiate some curiosity.
