I calculated extra strikes per game by dividing the area around the strike zone into 64 3-inch-square regions, considering left-handed and right-handed batters separately. In each region, I calculated the average catcher’s chance of getting a strike call. (The “average catcher” includes all catchers except for the one we’re specifically looking at.) I then asked how many pitches in that region our catcher of interest saw, and how many of them were strikes. The average catcher’s strike probability in that region tells us how many we would expect to be strikes. Subtracting the expected number of strikes from the actual number of strikes gives us the extra strikes our catcher saw in that region. I summed all the regions up, and divided by the number of games, to get the “Extra strikes per game” figure. To make my life easier, I only looked at games in which our catcher of interest caught at least eight innings (the vast majority of them); otherwise, I’d struggle with identifying which innings our catcher was actually responsible for.
