Maybe this is old news, maybe this isn't. But I just accidentally stumbled upon baseball-reference.com's minor league version of baseball reference while at baseball-reference.com.

What's the really cool thing about minors.baseball-reference.com? They've got actual league stats for the minor leagues now. So now we know, for example, that the 2007 FSL had a league .713 OPS this season with 4.48 runs per game per team average.
Just another valuable baseball site to bookmark and spend countless hours browsing.
