Component ERA (CERA)

 

Definition: A statistic that estimates what a pitcher's ERA should have been, based on his pitching performance.

ERC=(((H+BB+HBP)*PTB)/(BFP*IP))*9-.56

 

PTB in the formula is calculated as:

PTB=.89*(1.255*(H-HR)+4*HR)+.56*(BB+HBP-IBB)

 

When intentional walk data is not available you can use:

PTB=.89*(1.255*(H-HR)+4*HR)+.475*(BB+HBP)

 

Also, if the ERC is less than 2.24 the formula is adjusted as follows:

ERC=(((H+BB+HBP)*PTB)/(BFP*IP))*9*.75

 

History: The formula here is at it appears in the 2004 edition of The Bill James Handbook.
