Zone Rating on The Hardball Times
April 2, 2007 4 Comments
I did an article for The Hardball Times comparing the Zone Rating published by STATS for the last 20 years with a newer version, first published in John Dewan’s The Fielding Bible and now available on The Hardball Times.
I used the play by play data from Retrosheet to reconcile the data, checking out all the plays (assists and putouts) that Orlando Cabrera was involved in last year.† I learned some new things, like that on one putout, 2 fielders can be awarded an assist (like an outfielder hitting the cutoff man, who throws the runner out at the plate.)
I’m not as confident about the new zone rating data at other positions (more on this later), but for shortstops it looks like a step forward.
Also, here is an excellent blog post about the new zone rating.
