The Radar Gun at Kauffman Stadium is Hot

New, 19 comments


It has been pointed out a few times that the pitches at the K are a little high and I decided to look to see if it was true.

First, I had someone at the stadium check to see if the speed displayed was close to the Pitch F/X data.  It was dead on for the 20 pitches selected.

I took the average and max fastball speeds for all starters (Bannister, Greinke, Hochevar and Davies) that have had 2 games at home and 2 away.  I averaged the home and away number and then took the difference of these two numbers.  Here is the data.



4 Seam Fastball (mph)







Avg Max
Avg Max Diff in Avg Diff in Max
Greinke Home 93.52 97.6 Away 91.24 94

Greinke Home 93.55 95.6 Away 92.31 95.7

Greinke Home 93.05 95.8 - - -

Hochevar Home 95.21 97.2 Away 92.71 94.1

Hochevar Home 95.49 97.4 Away 92.19 93.9

It looks like the K is about 2 mph faster than the other stadiums visited so far this season.
