Lately it seems like I've heard more NL fans complaining about the allegedly "unfounded" assertions of the AL's superiority. So I decided to look about at the last few seasons W-L records in interleague and also use PythagenPat to check it out. I'm sure someone has done this before, but I couldn't find it anywhere after a grueling 10 minutes of Google searches.
Here's what I say. This isn't a complete reflection, but I did find the run differential info for 2005-2009. If anyone knows the obvious spot that I'm ignoring for this stuff, please buzz over to Driveline and let me know.
