To illustrate my point lets look at 2 ball parks : Comerica Park in Detroit and the new Yankee Stadium in New York.
HRs in 2011 avg HRs per game
Comerica Park 88 1.66
Yankee Stadium 130 2.32
Here we can clearly see that a lot more HRs are hit at Yankee Stadium then Comerica. Therefore you would expect that Tigers players would hit less HRs since they play half of their games there.
I fantastic website that I refer to often is the Hit Tracker website founded by Greg Rybarczyk (http://www.hittrackeronline.com/index.php). The information on this site is amazing and if you are at all interested in stats check it out. What they have done is calculate the true distance of HRs, that is the distance of the hit based on where it landed, the speed off the bat etc if there were no physical structure within the ball park to stop it. This true distance calculation is basically a true indication of how far the ball would have been hit if all ball parks were built the same.
After studying this website I found that this information could be used to calculate who the true HR champ would be if everyone played in the same sized ball park. If you go to the HR tacker website you can see that the true HR distance ranges from 323-486 ft. But a 323 ft HR by Sam Fuld (Rays) at Fenway down the right field line near Pesky Pole would not be a HR down the same right field line at Comerica Park (which would be about 340). Firstly lets look at the current HR (non-adjusted leader list):
|Bautista, Jose (Blue Jays)||31|
|Granderson, Curtis (Yankees)||28|
|Teixeira, Mark (Yankees)||28|
|Konerko, Paul (White Sox)||24|
|Cabrera, Miguel (Tigers)||22|
|Cruz, Nelson (Rangers)||22|
|Reynolds, Mark (Orioles)||21|
|Beltre, Adrian (Rangers)||20|
|Ortiz, David (Red Sox)||20|
|Quentin, Carlos (White Sox)||20|
Next let's look at the list if it is adjusted to the the number of HRs that are over the true HR distance of 400 ft (according to my calculations based in the data from the HR tracker website, BTW I know this is a huge hit but started with this as an exercise).
|Cruz, Nelson (Rangers)||22||17|
|Reynolds, Mark (Orioles)||21||16|
|Bautista, Jose (Blue Jays)||31||14|
|Lind, Adam (Blue Jays)||19||13|
|Beltre, Adrian (Rangers)||20||13|
|Quentin, Carlos (White Sox)||20||10|
|Ortiz, David (Red Sox)||20||10|
|Granderson, Curtis (Yankees)||28||10|
|Ellsbury, Jacoby (Red Sox)||17||10|
Quite a surprising result right? Here we can clearly see that Yankees players (Teixeira, Granderson) are benefiting from playing in Yankee Stadium more often.
