Interesting piece for a couple of days ago:
It falls about halfway on things we've been kicking around here: important metrics that are almost the same for him in the regular- and post-season (strikeout and walk rate), one that's much worse (HR).
It does give credence to the idea that it may be tied in with "the little voice in the back of your head":
That’s the math of the situation; it can’t change the feeling, though, the little voice in the back of your head that says “Hey, are you ready for this?” every time Kershaw pitches in October. And if the voice is in your head, you can be sure it’s in Kershaw’s too, every time he gives up a home run or a chain of singles. Is this all luck? Could it possibly be luck? How can it keep happening to me? Am I tipping my pitches? Pressing too hard? Not pressing hard enough?
Saying that someone might be pressing is, to me, just the flip side of saying clutch-hitting doesn't exist. (Which I agree with, although I'd allow that there are probably very isolated cases of players who do consistently perform well under pressure--an argument for somewhere else.) Sabermetrics doesn't buy clutch-hitting because a) the evidence isn't there, and b) why would it be?--you'd have to believe that athletes have some magical ability to change their abilities at key moments. But I also believe that athletes don't have magical abilities to not fall prey to something very human: that doubt creeps in when you don't succeed a few times in the same situation. It doesn't mean that you don't occasionally succeed--get a big hit, pitch a good game--just that the doubt lingers if you also keep back-stepping, and continues to linger until you definitively close that door, like Price did last year. I don't think Kershaw has done that yet. But I think he will at some point.

Believing in clutchness doesn't have to be tied in to a belief that someone can do it over an extended period of time. Someone can be clutch on a given day, where they do something they might not have done on another day because they were in a different frame of mind or they told themselves definitively, "I am going to do this now and I am not going to take no for an answer." I think that kind of stuff happens all the time.
