James Hoye - Projected Home Plate Umpire

Forty-one year old Hoye is a fairly new umpire when he became a full time MLB umpire in 2010. I am going to look at what type of strike zone we should expect from him today.

Last night it was mentioned that home plate umpire Jim Joyce was squeezing Dan Duffy. There are a couple of ways to determine how a umpire normally calls a game. One way is to go to Baseball Prospectus and look at their umpire stats. The number of a stats there can be a little over whelming, so just sort by SO/BB. Of the umpires with over 1000 PA umped, James Hoye ranks 61st out of 75 with a SO/BB of 1.97. The league median value is 2.14, so we can expect a somewhat smaller zone today.

Using the data BP just gives a general idea of an umpire's strike zone, but it doesn't show where in the zone he may call less strikes than the average umpire. Using the data from, here is how his called strike zone compares to the league average zone. The view is from the umpire's perspective and the scale is the percentage difference, in decimal format, compared to the league average.

For right-handed hitters, Hoye doesn't call as many inside strikes as the average umpire. He looks to make up for this discrepancy by calling more high inside strikes to left-handed hitters. The problem is that most hitters are right-handed, so he will be probably be pitcher friendly today.


If half of the Royals losses this season was directly attributed to one part of the game, what would you NOT want it to be:
