I should have made the point than that most of the Cubs players had BABIP well above their career averages. Would that be a valid enough point for you? For players with enough data -- yes -- for Theriot in particular, no. Depending on where a pitcher puts the ball, he can to an extent control how well a ball is hit. There are some -- but very few -- pitchers that have extreme BABips consistently -- The point is, BABIP is a valid predictive tool for both batters and pitchers when we don't have a whole lot of history to know where their averages might fall. No it is not. BABIP is NOT a good predictive tool for Runs -- OPS is MUCH better. OPS correlates to runs I think as well as anything except perhaps RC/27. Simply put, BABip does not correlate well to runs. as the overwhelming majority of MLB hitters hover around that mark with only a few exceptions I do not believe this to be at all true -- for pitchers I agree, for batters I do not. And to say that this doesn't apply at all to wins is a bit bogus too,...., something that it doesn't appear he is capable of doing. I didn't read your paragraph very close -- I would just take Theriot's CHONE projection (or another projection), and look at OPS, and compare it his 2008 OPS of .746. If his 2009 OPS projects higher -- I would say that regardless of BABip, Theriot will probably do as well or better than he did in 2008, if his 2009 OPS projects to a .670 then I would say you have a good argument that the Cubs will lose runs in Theriot's spot. It is a fact that OPS correlates to runs much better than BABip. But tell you what FTJ and Briggs. If Theriot equals or improves on his BABIP this next season, I'll buy you a beer. If he doesn't you buy me a beer. Deal? I will gladly give you one of my Homer wedding beers in either case... I don't think Theriot will increase his BABip next year -- however I don't think that is entirely relevant either. If you tell me his OPS is going to drop, then I will listen -- not so much for BABIP. If you want to shut me up -- Find a 2009 CHONE or other OPS projection for Theriot, and compare it to 2008. If they project his OPS much less than .746 -- I will concede the point.
