These are team run differential stats broken down based on matchups and HOME and AWAY. It should give you a more exact idea on where the runs come from and who it was against.
Initial idea inspired by Max Kellerman's obsession with run differential.
I took things a step further (or maybe even two steps) and decided to create run differential stats broken down by pitchers with decisions (ie. win/loss). It's hard to explain what it does so why don't you just check out Mike Mussina's breakdown.
