Does Arizona really play in a pitcher friendly park? I know the dimensions are in the pitchers favor but the ball carries very well in Arizona. Found this for 2009. I'm not sure you can say that the NL West is mainly a pitchers haven you do have San Diego, San Francisco, and Los Angeles but Arizona and Colorado are neutral to hitter friendly.
