Parks and Conversation
These notes don't fit into the post that I will hopefully have up tomorrow, but I thought I'd include this graphic of average ballpark dimensions from 2006-2008 here. I converted the dimensions found on Hit Tracker from pixels into feet, and here are the results by quartiles.
Also, last week I linked to a couple excellent studies on park factors by Greg Rybarczyk and David Gassko, but I forgot to to link to Jeff's excellent post on park factors, which I will be referencing as well in the future. Fortunately, his study used the same years of data as I did. It contains several useful pieces of information that I have not seen used in many other places, such as foul area, and average wall height, which is a key part of information missing from the above visual, but which can also be found at ballparks.com
Lastly, I'm interested in hearing thoughts on whether it would be more informative to list numbers other than just averages for home run characteristics. For example, the bottom 10% of home runs in a certain park might tell us how easy it is to hit short home runs, while showing perhaps the top 25% could tell us how well the ball carries in a park. Or for certain players, the top quartile will give an indication of a player's raw power, while the bottom half may tell us more about how he used his park to his advantage.
