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.[1] Hall of Fame outfielder, Babe Ruth, holds both the single-season and career OPSBI records.
Formula
The basic formula is
where OBP is on-base percentage and SLG is slugging average. These averages are defined as:
and
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:
