Why does everyone always assume that Fenway Park artificially inflates players' batting stats?  We're not talking Coors Field here with baseballs kept in humidors.  Remember, "what the Wall giveth, the Wall taketh away."  

Just ask Jim Rice, who would probably be a Hall of Famer if not for the 50-100 or so line drive shots he pummeled off the Wall in his career that otherwise would have been home runs in other ballparks.  Or anyone who has ever ripped a long single off the Wall that would have been an easy double or HR somewhere else.

There is some statistical help with the ballpark, but it's mostly related to the small foul territory which helps batters get extra chances on foul balls that might otherwise be caught.
