We've been talking a lot about reliever metrics lately, so coincidentally BP has a good article on their reliever tools up. Here's a little snippet about WXRL:

I had a series of articles that were really stat glossaries, and I'd link to them from time to time when questions came up. When the board migrated to its current form they kind of got lost in the archives. I think this will serve as a good replacement, there's already more here than was in the old articles.
