SoSH Glossary: Pitching Minus Statistics

SoSH Baseball Glossary

Baseball is filled with statistics, rules, and archaic terms that can often form what sounds like a foreign language. Sons of Sam Horn’s glossary provides a better understanding of these terms through straightforward definitions, clear explanations, and examples pulled straight from the baseball world. If there is anything you would like us to add to our glossary, please contact us.

Pitching Minus Statistics

Pitching minus statistics are versions of ERA, FIP, and xFIP that adjust for the pitcher’s home park and league so that his numbers can be compared with any other pitcher. The resulting number is then multiplied by 100. The statistic yields a value which, like ERA, decreases with effectiveness: Each point below 100 equals 1% above league average, while each point above 100 equals 1% below league average.

How Is It Calculated?

Things To Consider

  • The pitching minus statistics correct for the players’ eras allowing for comparisons across different time periods.
  • Park factors are only estimates, so they are imperfect. Some pitchers will be affected more than others.
  • The formula above can be used for ERA, FIP, or xFIP.
