[ Return To Top ]

Isolated Power (ISO) is a measure of a hitter's raw power, in terms of extra bases per AB. Its formula is ISO = (2B + (3B*2) + (HR*3)) / AB

In PECOTA, ISO is one of five primary production metrics used in identifying a hitter or pitcher's comparables. PECOTA uses a slightly modified version of Isolated Power that assigns the same value to triples as to doubles (extending a double into a triple is generally an indicator of speed, rather than additional power). Thus, the formula for PECOTA isolated power as follows: ISO = (2B + 3B + (HR*3)) / AB
