The era of electronic strike and ball calling is coming and soon. One could put an ear plug in the umpire or place a vibrator in his hand and have it feed back calls to him while he stands behind the plate to handle other issues like tipped balls, etc. I tend to be old school, but when I see umpires with variability behinnd the plate and when the electronics have progressed to where they are now, it can only help the game.
On another note related note, stats are kept but don't seem to be readily available regarding hitters taking called strike three. JBJ did it in the last inning for instance. Called strike three volume doesn't necessarily relate to win percentage as the Sox took a bunch and still won the world series. I do think a hitter with a large number of called strike threes doesn't see the pitches well and maybe doesn't know his strike zone. Certainly some called strike threes are on overly generous calls by the umpire, but one would think that would average out in a similar way for all hitters so a guy who has a lot of called strike threes has a problem picking up pitches. I looked at a list from 2013 ande noticed Napoli was high on the list of called strike thees for 2013. That's the only reference I could find.
