Last season, in baseball, there were more than 700,000 pitches thrown. Of those, nearly 400,000 were taken, or un-swung at. Every single one of those taken pitches was determined to have been a ball or a strike by a trained human umpire. Trained human umpires are very good at their jobs — to confirm, one need only watch an untrained human umpire. The umpires in the major leagues get almost every call correct. But they do miss some, and when it comes to nearly 400,000 called balls and called strikes, it stands to reason that there are going to be mistakes, and there are going to be really bad mistakes. It’s simple probability. Within any such data pool, there are going to be extremes.
Herein, we will reflect on the 2012 season’s worst called ball. That is, the called ball that was most like a strike. As it turns out, I actually wrote about this before, but at that point I had less than three months of data. Now I’m looking at data for the season entire. For the record, I’m not doing this to criticize the umpire, or to make some statement about instant replay and automated strike-zone judgment. I’m doing this for the sake of exploration, for the sake of curiosity satiation. As you watch what unfolds below, try not to be frustrated. Try instead to be interested. If anything, you should be trying to eliminate frustration from your life.
