Does anyone know where I can find a comprehensive collection of sabermetric definitions? Like VORP (Comp. Clueless), R/C (Runs Created, I know what it stands for but what about a formula?), ERA+ and the like. I just can't get a grasp on a lot of this stuff and don't really have the time to read "The Book" right now. I sometimes get lost on some of what we are talking about at times on here. I'm of course assuming that most of this lingo is from the MoneyBall guys. Certainly I understand the basics up too OPS, but after that I get a little lost.

Maybe we can even add a sticky about it somewhere. Thanks in advance for any help. Hope this isn't construed as a stupid question.

Not to be picky here, but what you're asking has nothing to do with Moneyball. It was all around well before Moneyball and Moneyball doesn't even mention most of it.

Go to baseballprospectus.com. That's probably the best source for sabermetric acronyms.

There aren't any stupid questions. Try this link (http://www.baseballprospectus.com/about/) first. Save it to your favorites. You don't have to read every article at once, but it's a great place to start.

The definition of VORP follows, but it is proprietary info and you won't find a formula for it. To get you started, heres the definition for Value Over Replacement Player.

VORP
Value Over Replacement Player. The number of runs contributed beyond what a replacement-level player at the same position would contribute if given the same percentage of team plate appearances. VORP scores do not consider the quality of a player's defense.

Ok, I'll fess up to one of these that I've always wondered about, what's LOOGY stand for? I know it means he's a left hander who gets out left handers, but I don't know the specific acronym.

It's not an exact acronym, but "Lefthanded One Out Guy" is what it stands for.

RC--Runs created. A stat from Bill James that projects how many runs a player created. There are a couple of dozen different formulas throughout history, with the appropriate one being in each case.
RCAA--Runs created above average. It's the difference between a player's RC total and the total for an average player who used the same amount of his team's outs. A negative RCAA indicates a below average player in this category.
RCAP--Runs created above average at his position. It's just like RCAA, except the comparision is to players at his position.
OWP--Offensive winning percentage. It's a Bill James stat that projects what a team's winning percentage would be if each offensive player was cloned to that player and the team had an average pitching staff.
RC/G--Runs created per game. It's a Bill James stat that projects how many runs a team would average per game, if everyone on the team was cloned to that player.
TB--Total bases
EBH--Extra base hits

SEC--Secondary average. The stat measures those offensive components that are not measured in batting average. The formula is (TB-H+BB+SB)/AB
