What is ops in baseball?

Babe Ruth achieved a career OPS of 1.164, the highest in MLB history, showcasing superior offensive production. This metric optimally assesses a player's combined hitting and power impact. Mike Trout consistently posts elite OPS numbers, affirming its value for modern player comparisons.

TL;DR

On-Base Plus Slugging (OPS) sums a player's ability to reach base and their power hitting into a single number. An average MLB figure sits around .730, while anything above .800 suggests an All-Star level performance. It's widely considered more useful than traditional batting average because it rewards walks and extra-base hits.

How Is OPS Calculated?

OPS is the mathematical sum of On-Base Percentage and Slugging Percentage, two statistics that track different aspects of a player's offensive output. This formula treats getting on base and hitting for power as equally important components of scoring runs for the team.

The calculation requires two separate inputs. First, find On-Base Percentage (OBP), which measures how often a player avoids making an out. Next, determine Slugging Percentage (SLG), which weights hits by the number of total bases earned. Adding these together creates the final OPS score.

Component What It Measures Calculation Focus
OBP Efficiency Hits, walks, and hit-by-pitches
SLG Power Total bases per at-bat
OPS Total Value The combined sum of OBP and SLG

Standard statistics can be misleading. A hitter with a high batting average might never walk or.

What Is a Good OPS Score?

A good OPS score typically starts at .800, while a score of .900 or higher indicates a superstar talent performing at the highest level. Most league average players hover between .710 and .750 depending on the current offensive environment of the season.

The scale helps fans quickly categorise player performance. Scores below .600 are usually considered poor, often leading to a player being benched or sent to the minor leagues. Conversely, truly historic seasons from legends like Babe Ruth or Ted Williams saw OPS figures climb well above 1.100.

OPS Range Performance Tier Examples
.900 or higher Elite / MVP Level Top tier sluggers

While OPS is helpful, it doesn't account for park effects or stolen bases. This is why analysts sometimes use "OPS+" to compare players across different eras and stadiums fairly.

How to Decide Which Hitting Metric to Use

Choosing a stat depends on what specific skill needs evaluation. Using OPS is best for a general overview of a player's threat at the plate.

  • Look at OBP if the goal is measuring plate discipline.
