As previously defined, the Factor12 Rating (F12) is an analytic measurement utilizing league average performance to compare the value of all MLB pitchers.<\/p>\n

In basic terms, F12 is a rating that takes into account 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.<\/p>\n

For example, Justin Verlander<\/a> opened the season at Comerica Park on Thursday and dominated the Boston Red Sox for eight innings.<\/p>\n

Verlander’s line of 8IP \/ 2H \/ 0R \/ 1BB \/ 7K currently produces a F12 Rating of 38.879.<\/p>\n

Yet, what does the 38.879 really mean?….                                                Verlander’s F12 values thru 4\/5\/12<\/p>\n

\"\"<\/div>\n

Through yesterday’s games, 78 pitchers have thrown 194.33 combined innings. Consequently, the average pitcher has thrown 2.49 IP (194.33\/78) in 2012. Using the average performance in each of the 12 categories, a percentage value is calculated for Verlander.<\/p>\n

The ten ratio statistics use a formula that produces a number with a fixed range (0.001 – 4.000).<\/p>\n

The IP and SO-BB categories do not use a fixed range, so it is possible to accumulate more than 4.000 points. This is done to give starting pitchers proper credit for their workloads.<\/p>\n

**The F12 Rating is simply the twelve stat values added together.<\/p>\n

**The average pitcher would earn a F12 Rating of 24.000.<\/p>\n

** F12 can be viewed as the percentage difference for each pitcher above or belowactual<\/em> MLB league average performance (F12%>AVG).<\/p>\n
