Awesome. I posted a link at McC as well.

This is great stuff

Just to clarify one thing that is a bit unclear: Is it the case that hitting large numbers of grounders increases BABIP and large numbers of flies decreases BABIP?

It makes sense, I’m just not sure I’m reading the description of the variable correctly.

That's correct.

That actually follows from what we already know about pitchers and BABIP: namely, that fly ball pitchers tend to have lower BABIP than ground ball pitchers.

Why does this whiff on Jason Bay so consistently?

That's an interesting question.

As I see it, there are two possible explanations:

1) Jason Bay does something else that we didn’t account for, or

2) Bay has simply rather consistently lucky. That’s not as silly as it sounds: sure, the odds of one player consistently exceeding expectations due to luck are remote, but the odds of it happening to someone are much higher. Why not Bay?

There are a few others, but I’m not sure how many would constitute more than would be expected. It misses pretty consistently on Jason Giambi, and theidea that immediately leaps reason is that the speed score you are using may not be sensitive enough at the bottom of it’s scale to correctly gauge how slow that slow-ass bastard is. He may be even slower than the typical player who doesn’t hit triples, steal bases or catch balls hit near him.
