You can see the listing of park ratings when creating a team. Otherwise I go to DiamondDope
Here's the link:
http://diamonddope.com/lineups.cfmAt the bottom of the page you'll see a drop down that says Zero Park Effects. Click the drop down and you can see the park ratings for each stadium.
The first example is:
3Com Park '99 (7, 1, 13, 9)
This park has a 7 Singles rating for LH batters, a 1 Singles rating for RH batters, a 13 HomeRun Rating for LH batters, a 9 HomeRun Rating for RH batters
Park Ratings go from 0-20, with 20 being the highest...……….
