What Stat Is OPS in Baseball? Meaning & Calculation

By Sarah Miller · October 26, 2052

OPS in baseball stands for On-base Plus Slugging, a key offensive statistic that combines a player’s on-base percentage (OBP) and slugging percentage (SLG) into one metric. It is calculated as OPS = OBP + SLG, providing a comprehensive measure of a player’s ability to both get on base and hit for power. An OPS above .800 is considered strong, while elite hitters often exceed 1.000.

What Is OPS in Baseball?

OPS, or On-base Plus Slugging, is one of the most widely used metrics in modern baseball analytics to evaluate a hitter’s overall offensive contribution. By combining two critical components—on-base percentage and slugging percentage—OPS offers a more complete picture than batting average alone.

Why OPS Matters in Evaluating Hitters

Measures both plate discipline and power hitting
Correlates strongly with run production
Used by front offices, analysts, and fans to compare players
Simplifies complex performance into a single number

Breaking Down the Components of OPS

Understanding OPS requires knowledge of its two foundational statistics: on-base percentage (OBP) and slugging percentage (SLG).

On-Base Percentage (OBP)

OBP measures how frequently a batter reaches base per plate appearance. It includes hits, walks, and hit-by-pitches but excludes errors and fielder’s choices.

Formula:
OBP = (H + BB + HBP) / (AB + BB + HBP + SF)

Slugging Percentage (SLG)

SLG evaluates a hitter’s power by weighting hits based on total bases. A home run counts more than a single, reflecting extra-base capability.

Formula:
SLG = Total Bases / At-Bats

How OPS Is Calculated: Step by Step

To calculate OPS, simply add OBP and SLG:

OPS = OBP + SLG

For example:
If a player has an OBP of .380 and a SLG of .520, their OPS is .900.

Interpreting OPS Values

The following table shows general benchmarks for evaluating OPS in Major League Baseball:

OPS Range	Performance Level
.9000+	Excellent (MVP-level)
.8333–.8999	Great
.7666–.8332	Above Average
.7000–.7665	Average
.6333–.6999	Below Average
.5666–.6332	Poor
Below .5666	Very Poor

2024 MLB Season Leaders in OPS: Real Data

Player	Team	OBP	SLG	OPS
Shohei Ohtani	Los Angeles Dodgers	.410	.650	1.060
Mookie Betts	Los Angeles Dodgers	.395	.580	.975
Aaron Judge	New York Yankees	.405	.560	.965
Bryce Harper	Philadelphia Phillies	.380	.540	.920
Yordan Alvarez	Houston Astros	.390	.520	.910

The 2024 season highlights Shohei Ohtani leading the league with a dominant 1.060 OPS, driven by elite slugging (.650) and strong on-base skills (.410). Players like Mookie Betts and Aaron Judge also rank highly, showing consistency in both reaching base and hitting for power. This data confirms that top-tier OPS values are typically achieved through excellence in both component stats.

Advantages and Limitations of Using OPS

Pros of OPS

Simple to understand and calculate
Strong correlation with team scoring and individual value
Widely accepted across media, broadcasts, and analytics
Better than batting average at predicting offensive impact

Cons of OPS

Gives equal weight to OBP and SLG, though OBP is generally more valuable
Does not adjust for park or league context
Can be skewed by small sample sizes
Lacks defensive or baserunning context

Because of these limitations, advanced metrics like wOBA (weighted On-base Average) and OPS+ have emerged as more refined alternatives.

Related Metrics: OPS+ and Adjusted OPS

OPS+ adjusts raw OPS to account for ballpark factors and league averages, setting 100 as the league average. Each point above 100 represents 1% above league average.

For example, an OPS+ of 130 means the player is 30% better than the league average after adjustments.

This makes OPS+ especially useful when comparing players across eras or different ballparks.

Frequently Asked Questions About OPS in Baseball

What does OPS stand for in baseball?

OPS stands for On-base Plus Slugging, a composite statistic that adds a player’s on-base percentage (OBP) and slugging percentage (SLG) to evaluate overall offensive performance.

What is a good OPS in MLB?

An OPS of .800 or higher is considered good in Major League Baseball. An OPS above .900 is excellent, and values over 1.000 typically indicate MVP-caliber seasons.

Who holds the all-time single-season OPS record?

Babe Ruth holds the record with a 1.232 OPS in 1923. His combination of high on-base (.455 OBP) and massive slugging (.777 SLG) remains unmatched in a single season.

Is OPS better than batting average?

Yes, OPS is a far better indicator of offensive value than batting average because it accounts for both getting on base and hitting for power, whereas batting average only considers hits divided by at-bats.

Why is OPS important for fantasy baseball?

OPS is crucial in fantasy baseball because it reflects a player’s consistency in reaching base and delivering extra-base hits, which contribute directly to runs and RBIs—key scoring categories in most leagues.
