How to Calculate On Base Plus Slugging Average

Sabermetrics is a popular statistical study in baseball that began in the 1970s, examining a number of intricate statistics that are then used to analyze the performance and "worth" of players on the field. One of the earliest and most often used of these statistics is the "on base plus slugging" percentage, which combines the on-base average and a slugging percentage to indicate a player's offensive value.

• 1

  Add the number of total bases accrued by a batter, with a single representing one, a double representing two, a triple representing three and a home run representing four.

• 2

  Determine the number of walks and hit-by-pitches accumulated by a hitter.

• 3

  Add the number from step one to the number of step two and divide this by the total number of plate appearances for a batter. The total will be the OPS average.
