1. What Does OPS Stand for in Baseball and What Does It Measure?
OPS in baseball stands for “On-Base Plus Slugging.” It is a comprehensive statistic that measures a hitter’s overall offensive performance by combining their ability to get on base (measured by On-Base Percentage or OBP) and their ability to hit for power (measured by Slugging Percentage or SLG). OPS provides a single number that evaluates a player’s total offensive contribution.
1.1. What Is the Significance of OPS in Evaluating Baseball Players?
OPS is significant because it offers a more complete picture of a hitter’s offensive capabilities than traditional statistics like batting average. By considering both the ability to reach base and hit for power, OPS reflects a player’s overall effectiveness in creating runs. It’s a quick and easy way to compare the offensive prowess of different players.
1.2. How Is OPS Calculated in Baseball?
OPS is calculated by simply adding a player’s On-Base Percentage (OBP) and Slugging Percentage (SLG). The formula is:
OPS = OBP + SLG
For example, if a player has an OBP of .350 and an SLG of .450, their OPS would be .800.
2. How Is On-Base Percentage (OBP) Defined and Calculated?
On-Base Percentage (OBP) measures how frequently a batter reaches base. It considers hits, walks (base on balls), and hit-by-pitches, while excluding times when a player reaches base due to an error, fielder’s choice, dropped third strike, or sacrifice bunt.
2.1. What Factors Are Included in the OBP Calculation?
The factors included in the OBP calculation are:
- Hits (H): Any batted ball that allows the batter to reach base safely.
- Walks (BB): Also known as base on balls, awarded when a pitcher throws four balls to a batter during a plate appearance.
- Hit by Pitch (HBP): When a batter is hit by a pitched ball and is awarded first base.
2.2. What Factors Are Excluded from the OBP Calculation?
The factors excluded from the OBP calculation are:
- At-Bats (AB): Official plate appearances, excluding walks, hit-by-pitches, and sacrifice bunts.
- Sacrifice Flies (SF): A batted ball that allows a runner to score but results in the batter being out.
- Errors: When a player reaches base due to a defensive error.
- Fielder’s Choice: When a fielder chooses to put out another runner instead of the batter.
- Dropped Third Strikes: When a batter reaches first base after the catcher fails to catch the third strike.
- Sacrifice Bunts: A bunt that advances one or more runners, with the batter being thrown out at first.
2.3. What Is the Formula for Calculating OBP?
The formula for calculating OBP is:
OBP = (H + BB + HBP) / (AB + BB + HBP + SF)
2.4. Who Are the All-Time Leaders in OBP in Major League Baseball?
The all-time leaders in OBP in Major League Baseball include:
- Ted Williams: .4817
- Babe Ruth: .474
- John McGraw: .466
- Billy Hamilton: .455
- Rogers Hornsby: .434

3. How Is Slugging Percentage (SLG) Defined and Calculated?
Slugging Percentage (SLG) measures a hitter’s power, representing the total number of bases a player accumulates per at-bat. Unlike batting average, SLG gives more weight to extra-base hits, such as doubles, triples, and home runs.
3.1. What Types of Hits Are Considered in the SLG Calculation?
The types of hits considered in the SLG calculation are:
- Singles (1B): One base hit.
- Doubles (2B): Two base hit.
- Triples (3B): Three base hit.
- Home Runs (HR): Four base hit.
Each type of hit is weighted differently, with more bases resulting in a higher SLG.
3.2. How Does SLG Differ from Batting Average?
SLG differs from batting average in that it gives more weight to extra-base hits. Batting average simply measures the frequency of hits, while SLG measures the total bases attained per at-bat, thus highlighting a player’s power-hitting ability.
3.3. What Is the Formula for Calculating SLG?
The formula for calculating SLG is:
SLG = (1B + 2B x 2 + 3B x 3 + HR x 4) / AB
Where:
- 1B = Number of singles
- 2B = Number of doubles
- 3B = Number of triples
- HR = Number of home runs
- AB = Number of at-bats
3.4. Who Are the All-Time Leaders in SLG in Major League Baseball?
The all-time leaders in SLG in Major League Baseball include:
- Babe Ruth: .690
- Ted Williams: .634
- Lou Gehrig: .632
- Albert Pujols: .620
- Jimmie Foxx: .609

4. What Is a Good OPS in Baseball?
A “good” OPS in baseball can vary depending on the era and the league, but generally:
- .800 or higher: Excellent. This indicates a player is a significant offensive contributor.
- .700 – .800: Above average. A solid offensive player.
- .600 – .700: Average. A serviceable offensive player.
- Below .600: Below average. Indicates a player who struggles offensively.
4.1. How Does OPS Vary Across Different Eras in Baseball?
OPS values can vary across different eras in baseball due to changes in the game, such as pitching styles, ballpark dimensions, and the prevalence of performance-enhancing substances. For example, the “steroid era” of the late 1990s and early 2000s saw inflated offensive statistics, including OPS.
4.2. What Is Considered an Average OPS for MLB Players Today?
As of today, an average OPS for MLB players typically falls between .700 and .750. This range represents the mean offensive output of a typical MLB player.
4.3. Who Are Some Current MLB Players with Consistently High OPS?
Some current MLB players with consistently high OPS include:

5.2. What Role Does OPS Play in Trade and Free Agency Decisions?
OPS plays a significant role in trade and free agency decisions. A player with a high OPS is generally seen as more valuable and can command a higher salary or trade return. Teams use OPS to assess a player’s offensive contribution and predict future performance.
5.3. Can OPS Be Misleading? What Are Its Limitations?
While OPS is a valuable statistic, it has limitations:
- Context-Neutral: OPS does not account for the context of the game, such as the score, inning, or runners on base.
- Park Factors: OPS does not adjust for park factors, which can significantly influence offensive statistics.
- Does Not Differentiate: OPS treats OBP and SLG equally, which may not always be appropriate. Some argue that OBP is more important for run creation.
- Ignores Defensive Value: OPS only measures offensive performance and does not consider a player’s defensive abilities.
6. What Are Some Advanced Baseball Statistics Related to OPS?
Several advanced baseball statistics are related to OPS and provide a more nuanced view of a player’s offensive performance:
- wOBA (Weighted On-Base Average): Assigns different weights to each type of hit and walk based on their actual run value.
- OPS+ (Adjusted OPS): Normalizes OPS to account for park factors and league averages, with 100 being the average.
- ISO (Isolated Power): Measures a hitter’s raw power by subtracting batting average from slugging percentage.
- BABIP (Batting Average on Balls in Play): Measures how often a batted ball becomes a hit, excluding home runs.
6.1. What Is wOBA and How Does It Relate to OPS?
wOBA (Weighted On-Base Average) is an advanced statistic that assigns different weights to each type of hit and walk based on their actual run value. It is more accurate than OPS because it accounts for the varying impact of different offensive events. wOBA is designed to measure a player’s overall offensive contribution in terms of run creation.
6.2. What Is OPS+ and How Does It Adjust for External Factors?
OPS+ (Adjusted OPS) normalizes OPS to account for park factors and league averages. It is scaled so that 100 is the league average. An OPS+ of 120 means a player’s OPS is 20% above the league average, adjusted for the ballpark in which they play.
6.3. How Do ISO and BABIP Provide Additional Insights into a Player’s Offensive Performance?
- ISO (Isolated Power): Measures a hitter’s raw power by subtracting batting average from slugging percentage. It provides insight into a player’s ability to hit for extra bases.
- BABIP (Batting Average on Balls in Play): Measures how often a batted ball becomes a hit, excluding home runs. It can indicate whether a player is getting lucky or unlucky with their hits.

- Luck: Random variations in batted ball luck can influence run production.
8. OPS vs. Other Traditional Baseball Statistics
OPS is often compared to other traditional baseball statistics like batting average, home runs, and RBIs. While each statistic provides valuable information, OPS offers a more comprehensive view of a player’s offensive performance.
8.1. How Does OPS Compare to Batting Average?
OPS is superior to batting average because it considers both the ability to get on base and hit for power. Batting average only measures the frequency of hits and does not account for walks or extra-base hits.
8.2. How Does OPS Compare to Home Runs and RBIs?
While home runs and RBIs are important offensive statistics, they do not provide a complete picture of a player’s offensive ability. OPS considers both the ability to get on base and hit for power, making it a more versatile and informative statistic.
8.3. What Are the Strengths and Weaknesses of Using OPS Compared to Other Stats?
Strengths of OPS:
- Comprehensive: Combines OBP and SLG into one number.
- Easy to Calculate: Simple addition of OBP and SLG.
- Predictive: Strong correlation with run production.
Weaknesses of OPS:
- Context-Neutral: Does not account for game context or park factors.
- Equal Weighting: Treats OBP and SLG equally, which may not always be appropriate.
- Ignores Defense: Only measures offensive performance.
9. What Are Some Criticisms of OPS and Alternative Viewpoints?
Despite its usefulness, OPS has faced criticisms and alternative viewpoints:
- Equal Weighting: Some argue that OBP is more important for run creation and should be weighted more heavily than SLG.
