What does the Factor12 Rating Really Mean? Baseball Stats 101

Saturday April 14th, 2012

Josh Robbins (Guest Writer):  As previously defined, the Factor12 Rating (F12) is an analytic measurement utilizing league average performance to compare the value of all MLB pitchers on 60ft6in.com.

In basic terms, F12 is a rating that utilizes all aspects of pitching.  It produces a number on a scale of 0.000-infinity (theoretically), where the average pitcher’s value is 24.000.

For example: Justin Verlander opened the season at Comerica Park last week and dominated the Boston Red Sox hitters for eight innings.  8IP/ 2H/ 0R/ 1BB/ 7K or F12 Rating: 38.907

In last week’s games: 137 pitchers appeared in a MLB game while compiling 351.67 innings pitched.  As a result, the average pitcher threw 2.57 IP in the opening week of 2012 (351.67/137).

Yet, what does the 38.907 really mean?

The IP and SO-BB categories do not use a fixed range (0.001-4.000).

So, it is possible to accumulate more than 4 points.
