"The numbers are strictly based on performance and not normalized. However there have been more hitter-friendly ballparks built since 2000, than pitcher-friendly. By my count, based on homeruns allowed as compared to the mean, Great American, Miller, Citifield, Yankee, Citizens, PNC are all more hitter friendly than their predecessor. And that wasn't a typo on Citifield, last year Citifield was above the mean in HRs allowed. On the other end, only Busch, Petco, and Nationals appear to be less slugger friendly than their predecessors."
But, his argument for hitters s based on slugging percentage, while his argument for pitchers is based on WHIP. So, looking solely at HRs, doesn't tell the story for either.
Until he does a better job at normalization, and uses consistent metrics across the comparisons, this is just a useless exercise.
