Fenway Park, Boston

The oldest ballpark in baseball, Boston's beloved Fenway Park (1912-present) has undergone many renovations in the last twenty years, though none as obvious as the 2003 addition of seating to the top of the once-precariously thin Green Monster in left field. That Monster compensates (somewhat) for the shortest corners in baseball (310 in the Monster's left field corner, 302 to Pesky's Pole in right). The park is deep to the alleys (379-380) but this isn't enough to make up for the Monster's propensity to turn fly balls into singles. The park is also so cozy that foul territory is very scarce, further inflating batting averages. Fenway has been the best AL park for hitters for a century now, and that situation doesn't seem likely to change anytime soon.

ParkFactors.com is brought to you by ScoutingBook.com, using weather information provided by the national weather office. Wind direction is averaged to the nearest cardinal point and adjusted to ballpark orientation. Wind descriptions are provided using the Beaufort Standard Scale of wind terminology, ranging from 'still air' to 'hurricane' force. Park Factor is calculated differently by different analysts. Our Park Factor summary formula uses the mean of runs scored and home runs hit per game at home vs away, where 100 would be a perfectly-average park.
