Jeff Zimmerman of Fan Graphs crunched the numbers on the umpiring crew assigned to the World Series, using Pitch-F/X data along with strikeout and walk rates to rank the six umpires from most pitcher-friendly to most hitter-friendly:
Hirschbeck, who in addition to being pitcher-friendly is also the crew chief, will be calling balls and strikes in Game 1 and, if the series goes the distance, Game 7 as well.
Zimmerman delved even deeper into the data, breaking out “heat maps” for each umpire’s strike zone for right-handed hitters and left-handed hitters. The whole thing is definitely worth checking out, but I’ll quote this one bit of analysis: “At least none of these umpires are at the extreme ends of the strike zone spectrum. Compared to the previous playoff series … this crew’s strike zone should be one of the more consistent ones.”
