The BABIP stat is flawed because it assumes hitters have zero control over how well they center the bat on the ball and where the ball is hit. People using BABIP are not assuming it's completely a luck stat, or else they would predict a league average BABIP for everyone. For any stat, the observed spread is always larger than the true spread in talent. That's how sample statistics work. The farther away a stat is from the mean, the larger regression we generally expect. Having a .350 BABIP is like a guy hitting 70 HRs. You could argue that he should be expected to do it again but the odds say that you would be wrong. Conversely, we wouldn't predict a league average number of HRs from him, either. The best guess would lie between the two. Theriot is very skilled at shooting base hit after base hit to RF. That is a skill, not luck as strawbossisevil implies. In the old days it was referred to as ability to "handle the bat". So how the heck do you explain his .289 BABIP in 2007? He was below league average! Was he working on his throwback/bat-handling skills during the 2007-2008 off season or did he still have all those skills in 2007 but was simply the victim of bad luck? The most likely explanation, of course, is that his true skill is somewhere between his 2007 and 2008 BABIP. The projections predict a slightly above average BABIP from Theriot. .315 looks like a good guess. He still is projected to hit well for a SS in 2009, though.
