Key Takeaways

  • On-base Plus Slugging (OPS) combines a player’s on-base percentage (OBP) and slugging percentage (SLG) to provide a comprehensive metric of offensive performance, measuring both the ability to reach base and hit with power.
  • To compute OPS, add a player’s OBP (hits, walks, and hit by pitches divided by plate appearances) and SLG (total bases divided by at-bats). For example, Mike Trout’s 2019 season OPS was 1.074, highlighting his exceptional skills.
  • OPS includes OBP, which reflects a player’s consistency in reaching base, and SLG, which emphasizes the quality of hits by valuing extra-base hits. Together, they offer a complete picture of a player’s offensive contribution.
  • OPS is crucial for evaluating a player’s overall offensive value, aiding teams in lineup decisions, player scouting, and performance analysis. It is highly correlated with run production and team success.
  • OPS+ adjusts OPS for league and park factors, providing a normalized comparison across different eras and environments. An OPS+ of 100 is average, with higher values indicating better performance relative to the league average.

What Does OPS Mean in Baseball

OPS is calculated as the sum of a player’s on-base percentage and slugging percentage. This statistic provides a comprehensive look at a hitter’s ability to get on base and hit with power; it brings these aspects together into one valuable number.

On-base percentage measures how often a player reaches base by receiving a hit, a walk, or being hit by a pitch. The slugging percentage calculates the quality of hits by assigning different weights to singles, doubles, triples, and home runs. OPS combines these two important statistics to reflect a hitter’s ability to get on base and hit with power.

OPS has been widely accepted as the key index of a player’s offensive value. The higher the OPS, the better the player at getting on base and hitting with power. This is a method that enables fans, analysts, and teams to better understand and compare the true hitting effect of different hitters. The table below determines the quality of hitters depending on their OPS rating.

OPS RangeHitter Quality
Above .900Excellent
.800 to .899Very Good
.700 to .799Above Average
.600 to .699Below Average
Below .600Poor

Formula for Calculating OPS

The OPS formula is a useful tool for evaluating a baseball player’s performance. It combines on-base percentage (OBP) with slugging percentage (SLG) to provide a single number that indicates how well a player both gets on base and hits for power.

The formula is simple:

  • OPS = OBP + SLG

Here’s how you calculate OPS with real data:

  1. Figure out the player’s OBP by dividing the sum of hits, walks, and hit by pitches over at-bats, walks, hit by pitches, and sacrifice flies.
  2. SLG is found by dividing the total bases a player earned by their at-bats.
  3. To get the OPS, just add OBP and SLG.

Let’s use Mike Trout’s 2019 season for an example:

Sacrifice Flies4
Total Bases299

Start with Mike Trout’s OBP:

  • OBP = (137 + 110 + 16) / (470 + 110 + 16 + 4) = 0.438

Then, find his SLG:

  • SLG = 299 / 470 = 0.636

Finally, his OPS is:

  • OPS = 0.438 + 0.636 = 1.074

Mike Trout’s 2019 season showed exceptional offensive skills when his OPS was calculated using the OPS formula. With an OPS of 1.074, he proved to be one of the top performers in baseball. His impressive stats demonstrate his ability to both get on base and hit with power.

Two Components of OPS

OPS, on-base plus slugging, is a way to measure a baseball player’s performance when it comes to offense. Basically, it combines on-base percentage with slugging percentage. Traditionally, batting average was the sure way to judge a player’s offensive skills, but OPS can do more than that; in fact, it gives a more complete picture of the hitter’s ability to aid his team in scoring more runs.

On-base percentage measures how a player gets on base with hits, walks, or getting hit by pitches. This is calculated by adding up all hits, walks, and times hit by a pitch and dividing the sum by the total plate appearances. A high OBP means consistency in getting on base and will be the genesis of creating and exploiting all scoring opportunities.

On the other side, the slugging percentage measures a player’s power hitting. This is the division of the total bases by at-bats. Basically, this number places greater value on extra-base hits than a standard batting average would. Hence, a higher SLG equates to a player’s ability to hit for extra bases and drive in runs.

On-Base Percentage (OBP)(H + BB + HBP) / (AB + BB + HBP + SF)Ability to reach base
Slugging Percentage (SLG)(1B + 2 × 2B + 3 × 3B + 4 × HR) / ABPower hitting ability

Combining OBP and SLG in OPS gives a complete picture of the player’s offensive prowess. It captures the ability to get on base and hit for power—two of the most critical skills in scoring runs. A high OPS indicates an elite hitter and is difficult for opposing pitchers to deal with, leading to the success of the team.

While OPS is not a perfect indicator, it certainly is a very valuable measure, one that is best used with other offensive statistics. It helps judge and compare players across different eras and teams. Knowing its parts can deepen one’s appreciation of the wide range of skills in an offensive baseball player.

What is Slugging Percentage?

Slugging percentage is one of the most important metrics in baseball, which evaluates the power hitting of a hitter. It evaluates total bases that a player gains per at-bat, giving insight into their offensive ability greater than just batting average. In the OPS formula, slugging percentage is a highly important ingredient that puts together a player’s value in offense.

It differs from the batting average, where not all hits are treated equally, by ascribing each type of hit by value according to the bases it achieves. A one-base hit gets one point; a two-base hit doubles that value, and so forth, up to four points for a home run. This design takes into consideration those players who excel in hitting extra bases, pointing out that they are the power hitters.

Formula for Calculating Slugging Percentage

For a player’s slugging percentage, one must tally their hits, doubles, triples, home runs, and at-bats. The computation is:

SLG = (1B + 2 x 2B + 3 x 3B + 4 x HR) / AB

This simplifies as:

  • 1B = Singles
  • 2B = Doubles
  • 3B = Triples
  • HR = Home Runs
  • AB = At-Bats

Let’s adopt an example to elucidate slugging percentage calculation. Consider a player’s season, where they have:

At-Bats (AB)500
Singles (1B)100
Doubles (2B)30
Triples (3B)5
Home Runs (HR)25

To derive the player’s slugging percentage, substitute these numbers in the formula:

SLG = (100 + 2 x 30 + 3 x 5 + 4 x 25) / 500

This further resolves into:

SLG = (100 + 60 + 15 + 100) / 500

SLG = 275 / 500

SLG = 0.550

The resultant slugging percentage for our player is 0.550. This value means they accumulate 0.550 total bases in an average at-bat. A slugging mark of 0.550 reflects superior performance in power hitting.

Using slugging percentage is a means for one to more accurately judge a player’s offensive capabilities. This includes their prowess in extra-base hits and their ability in power hitting. Its application proves important for the assessment of a player’s worth in offensive capabilities and influence on scoring.

What is On-Base Percentage?

On-base percentage is a great measuring stick for baseball; it gives a player’s ability to reach base safely. It accounts for hits, walks, and being hit by a pitch. Thus, it gives a more complete picture regarding a player’s ability to contribute to his team’s offense. A high OBP is an asset in that it shows that a player can regularly get on base, facilitating more chances for scoring.

This is a metric that impacts the game with regard to scoring. Players with high OBPs have more chances at contributing to their team’s runs. It is important in determining a player’s offensive value. Analyzed by teams, analysts, and fans, OBP has gained great significance in the sport.

Formula for Calculating On-Base Percentage

Calculating OBP involves totaling hits, walks, and hit-by-pitches, then dividing by at-bats, walks, hit-by-pitches, and sacrifice flies. The formula stands as: OBP = (H + BB + HBP) / (AB + BB + HBP + SF)

Let’s break down the critical parts of the OBP formula:

  • H: Hits – Includes singles, doubles, triples, and home runs.
  • BB: Walks – Is when a player receives a base on balls from the pitcher.
  • HBP: Hit by Pitch – Refers to being hit by a pitch, ensuring a player safely reaches base.
  • AB: At-Bats – Counts times a player has batted, not counting free passes, sacs, or hit-by-pitches.
  • SF: Sacrifice Flies – Is when a player hits a fly ball, allowing a runner to score.

For an example, let’s use a player with these stats:


Plugging the given values into the OBP formula, we find the player’s on-base percentage:

OBP = (150 + 50 + 5) / (500 + 50 + 5 + 3)
OBP = 205 / 558
OBP = 0.367 or 36.7%

In this instance, the player achieved a 36.7% OBP, reaching base almost 37% of their plate appearances. This demonstrates an excellent OBP within today’s baseball standards.

Why is OPS Important?

OPS is unique in baseball in offering a fully rounded view of a hitter’s value in the batter’s box. It combines on-base and slugging percentages to measure a player’s ability to get on base safely and hit with power, both of which are important for scoring runs. Thus, OPS becomes one of the most important metrics for player appraisal and team success prediction.

It is critical because it is highly correlated with run scoring. Teams with higher collective OPS scores tend to score more, thereby earning more victories. Knowing athletes with tremendous OPS numbers allows teams to optimize their lineups for greater offensive production, thus giving them a greater chance to win.

Moreover, OPS allows player comparison across time and leagues. Statistics like batting average and home run tallies can change based on differences in the size of parks or league tendencies. In contrast, OPS gives a more consistent measure of a hitter’s offensive production. It equips analysts with the ability to fairly compare players across different contexts and realize their impact on their teams.

TeamOPSRuns ScoredWin Percentage
New York Yankees.789858.636
Los Angeles Dodgers.774886.654
Houston Astros.820920.660

This table illustrates a direct link between OPS, run production, and winning. The Astros, with top standings in OPS, runs, and wins, show just how much of an edge strong offensive values can provide. That reinforces the importance of the metric in assessing the performance of a team.

On the individual level, OPS is of the utmost importance when it comes to scouting and coaching. It provides the best view into a player’s offensive capability, aiding in singling out those with better power and those who can get on base better. It is necessary to optimize lineups, pick the right players, and develop them.

Basically, OPS is a very important metric in modern baseball analysis. It encapsulates how players can actually produce runs and what they can add to a team, which essentially serves as the cornerstone in performance evaluation and decision-making. Its role in both individual and team assessment creates its importance in the sport’s analysis at all levels.

What is OPS+?

OPS excels in showing how well a player does offensively, but when it comes to comparing performances across different stadiums and times, it falls short. That is where OPS+ comes in. It is OPS tweaked to make the statistics level, making it easier to judge players from any era or team fairly.

OPS+ reflects the league’s OPS average and stadium factors. That gives us a clearer idea of how a player really stands out in offense in the league. It makes comparisons of athletes playing in different conditions or eras of offense fairer.

OPS+ uses a 100-point scale to measure player performance. A score of 100 indicates average performance compared to the league. Ratings above 100 indicate performance better than average, while ratings below 100 indicate performance below average. For example, an OPS+ of 150 means a player’s performance is 50% better than the league average, while an OPS+ of 80 means the performance is 20% worse.

OPS+ ValueInterpretation
100League average
11010% better than league average
12020% better than league average
9010% worse than league average
8020% worse than league average

Using OPS+, you can compare how players stack up offensively, no matter the team or stadium the player resides in or the era. This fine-tuned metric is important for assessing trade options, free-agent picks, or historical performances. It really peels back the layers to show a player’s true offensive worth, no matter the specific conditions.

OPS+ is key in the toolkit for sizing up a player’s offensive clout against the league’s norm. It smooths out the rough spots, offering a clearer, just evaluation of how a player performs. That makes it a must-have for teams, analysts, and fans keen on getting down to the nitty-gritty of understanding the game’s statistics.

What is a Good OPS in Baseball?

Knowing what the range is with OPS, it’s important to realize when considering a player’s offensive production in baseball. But the notion of a “good” OPS is relative to eras and leagues. However, general benchmarks can be established to help define a player’s value.

A good OPS is over .800, Which represents a good base presence and power hitting. Those players help their team score more runs when they step up to the plate. They typically fall among the league’s best hitters with this OPS.

For the upper-echelon hitters, an OPS over .900 is the gold standard. These elite players produce superior offensive results consistently. Their incredible power and base-reaching capabilities qualify them as perennial All-Stars and MVP candidates.

To contextualize OPS, here are some key ranges and what they signify in terms of offensive prowess:

OPS RangeOffensive Production
Above .900Elite
.800 – .899Very Good
.750 – .799Above Average
.700 – .749Average
.650 – .699Below Average
Below .650Poor

The league’s average OPS usually falls around .750. Thus, players above this mark are solidly above average. Conversely, players below it are considered below par in offensive contributions.

A player’s OPS can be difficult to understand without considering some components within the context of performance. The era, ballparks at home, and league offensive standards are all influential. Advanced metrics, such as OPS+, are useful. These metrics normalize disparate factors to offer precise, inter-era, and inter-league evaluations of players.

Who has the Highest OPS in Baseball?

There have been many legends in baseball who have shown their great offensive skills and made records with their bat. Among such heroes, some names shine brighter. Iconic Babe Ruth, who was a powerhouse with the Yankees, tops this list with a career OPS of 1.1636. His skill at getting on base, coupled with unmatched power hitting, defines an era.

Ted Williams and Lou Gehrig stand right there with Ruth, their names etched among the greats. Williams—a Boston icon—carried an impressive 1.1155 OPS over his career. His keen batting eye and dual threat in the box made him unique. Lou Gehrig, or the Iron Horse, has a career OPS of 1.0798, denoting tremendous consistency and might throughout his fabled career.

In 2004, Barry Bonds achieved an outstanding 1.4217 OPS. Despite the controversy, his exceptional ability to patiently draw walks and demonstrate pure power placed him in a league of his own.
