Analyzing the Strike Zone as a Three-Dimensional Volume – The Hardball Times

Really interesting stuff. Of course, if all the true strikes were called correctly, all hitters might go all Joey Votto.

Umpires Are Less Blind Than They Used To Be

Umps are getting better, and they’re also remarkably consistent. An ump who makes more accurate calls in one year will likely do the same the next; an ump who misses more calls in a given season will likely be as bad the next. Umpire accuracy is more steady than a player’s batting average or a pitcher’s ERA, and as consistent as OPS (on-base plus slugging) and wins above replacement.

Also interesting: umpires lately have been calling more strikes strikes, while calling an equal rate of balls balls, a pattern which may be part of the fall in offense over that period (my own speculation, not the author’s).
