On-base plus slugging plus runs batted in

On-base plus slugging plus runs batted in (OPSBI) is a baseball statistic calculated as the normalized sum of a player's on-base percentage and slugging percentage added to their runs batted in. Former Major League Baseball general manager, Jim Bowden, created this statistic. Hall of Fame outfielder, Babe Ruth, holds both the single-season and career OPSBI records.

Formula

The basic formula is

O P S B I = ( ( O B P + S L G ) ∗ 1000 ) + R B I

where OBP is on-base percentage and SLG is slugging average. These averages are defined as:

O B P = H + B B + H B P A B + B B + S F + H B P

and

S L G = T B A B

where:

  • H = Hits
  • BB = Base on balls
  • HBP = Times hit by pitch
  • AB = At bats
  • SF = Sacrifice flies
  • TB = Total bases

    • Rewriting the expression to account for the different denominators yields the final expression for OPSBI:

    O P S B I = A B ∗ ( H + B B + H B P ) + T B ∗ ( A B + B B + S F + H B P ) A B ∗ ( A B + B B + S F + H B P ) ∗ 1000 + R B I
