Jeff Sullivan of *Fangraphs* does an excellent job of figuring out what Koji’s worst pitch was during the playoffs. Of course, my favorite paragraph might be:
> The next step is to eliminate any remaining pitches thrown to Jose Iglesias, because Iglesias is far from a threatening sort. The worst he’s likely to do is slap a single somewhere, and that’s just not that bad. You always have to account for batter identity. By removing pitches thrown to Iglesias, we reduce the sample to six.
Poor Jose.
