Thanks for a point I wasn't aware of. But I guess I shouldn't be suprised. After all, unless you are named Dusty Baker there are tons of obvious baseball things that were disproven by math.
Although I understand the overall concepts, I'm not a SABR expert. I would assume that in this case, one of the main issues is around sample sizes. A batter just doesn't face a pitcher enough to know if his success/failure is indicative of a true trend or just short term results that will regress to the mean.
Do you know more about those studies GotowarMissAgnes and anything in the results as to why it is not predictive data? Is it sample size or are there other factors in play?
There are a few things with the New York Yankees that never change. That's pride, tradition, and most of all, we have the greatest fans in the world. -Derek Jeter, 9/21/08 -- last words from old Yankee Stadium
