Fantastic article over at THT by Justin Inaz discussing the variety of run environments among the affiliated leagues. Its widely known how pitcher friendly the FSL is, and this research reflects that, as it has the lowest run environment both in terms of Base Runs and Actual Runs. The next five lowest in order are the GCL, International, NY-PA, Midwest, and Eastern Leagues. The Mets have affiliates in every one of those leagues save the Midwest. The highest run environment the Mets have an affiliate in is the Appy League, where Wilmer Flores made a name for himself. The South Atlantic League, where Wilmer spent 2009, is just about middle of the pack. Its worth keeping all this in mind when regarding Mets prospects. Almost all of their affiliated teams play in leagues that are much more pitcher friendly than most other leagues at the same level. Hitters in the system are much more likely to get undervalued and pitchers much more likely to get overvalued.
