Analyzing the Umpires: Play-In Games Edition

September 30, 2013

Here is a quick look at the called strike zone and strikeout and walk rates for the three home plate umpires over the next three nights.

Monday: Rays vs. Rangers

Jeff Kellogg is basically league average. His called zone is expanded low and squeezed a bit on the sides. Left-handed hitters may expect to see a little bigger strike zone than right-handed hitters.

2013 Rates
K/9: 7.0 (League Average: 7.0)
BB/9: 2.6 (League Average: 2.8)

Tuesday: Reds vs Pirates

Joe West is a little more likely to call a strike than the average umpire. For both right and left handed hitters, he likes to call the low strike on the 3B side.

Wednesday: Indians vs Rangers/Rays winner

Gerry Davis is kind of a pitcher’s friend. He has one of the league’s highest strikeout and lowest walk rates this year, but it would be tough to tell with his called strike zone. He does not like to call the inside strike to both left and right-handed hitters. Instead he extends the zone both up and down a bit.
