On-base plus slugging percentage

On-base plus slugging (OPS) is a sabermetric baseball statistic calculated as the sum of a player's on-base percentage and slugging average. The ability of a player both to get on base and to hit for power, two important offensive skills, are represented. An OPS of .900 or higher in Major League Baseball puts the player in the upper echelon of hitters. Typically, the league leader in OPS will score near, and sometimes above, the 1.000 mark.

The basic equation is

${\displaystyle OPS=OBP+SLG\,}$

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

${\displaystyle SLG={\frac {TB}{AB}}}$

and

${\displaystyle OBP={\frac {H+BB+HBP}{AB+BB+SF+HBP}}}$
