In Erik Siegrist’s article in Baseball Prospectus on divisional park factors (link is subscriber-only), he notes how the parks in various divisions in the aggregate have certain characteristics. Given that half of road games tend to come against divisional rivals, it makes it clear that pitchers in the NL East have a great advantage… what surprised me (and Siegrist himself) was that the AL West parks as a group boost power, despite the presence of Safeco and Edison Field. Great for the Mariner hitters in my fantasy teams I guess…
It also made me think about how a team is constructed: maybe a player is undervalued because he would be a perfect hitter not just for your park (this is well known - many hitters on the Sox are specifically ones that have just the right swing for Fenway), but for your division.
