Adjusted Pitching Runs: Measures pitching production in terms of runs prevented above average.

A method introduced by Pete Palmer in the book "Total Baseball" to calculate a pitcher's value in runs above average. It is calculated differently here than in "Total Baseball."


APR = L * IP - R / pf(P)

  • L: Average number of runs per inning pitched in the league
  • IP: Innings Pitched
  • R: Runs Allowed
  • pf(P): park factor for the player's home park P.

This measure was introduced by Michael Wolverton here.
