OPS, or On-base Plus Slugging, has become a pivotal statistic in baseball, offering a more holistic view of a player's offensive capabilities than traditional metrics. Since its inception, OPS has grown in importance among coaches, players, and analysts as a key indicator of a player's overall effectiveness at the plate.
OPS is the sum of a player's On-base Percentage (OBP) and Slugging Percentage (SLG), two components that measure different aspects of offensive performance. On-base Percentage (OBP) quantifies how frequently a player reaches base per plate appearance, including hits, walks, and hit-by-pitches.
Slugging Percentage (SLG), on the other hand, reflects the total number of bases a player records per at-bat, emphasizing the value of extra-base hits. The combination of these metrics into OPS provides a comprehensive picture of a player's ability to get on base and to hit for power.
Yes, walks do count towards a player's OPS as they contribute to the on-base percentage (OBP), a crucial component of OPS. Walks are valued because they reflect a player's discipline at the plate, enhancing their OBP and, therefore, their overall OPS. However, a high OPS also requires a strong slugging percentage, as it measures the ability to achieve extra-base hits.

The concept of OPS dates back to the early 20th century but only gained prominence in recent decades as part of the sabermetrics revolution in baseball. Initially overshadowed by traditional statistics like batting average, OPS has come to be recognized for its superior ability to evaluate a player's overall offensive contribution. It contrasts sharply with batting average, which does not account for the type of hits or a player's ability to draw walks, thus offering a more limited view of performance.
OBP is calculated by dividing the sum of hits, walks, and hit-by-pitches by the sum of at-bats, walks, hit-by-pitches, and sacrifice flies. This metric is crucial because it measures a player's proficiency in reaching base, thereby providing opportunities for scoring runs, which is fundamental to winning games.
The slugging percentage is computed by dividing the total number of bases achieved from hits by the number of at-bats. It differentiates between single, double, triple, and home run, assigning a weight to each based on the number of bases covered. This differentiation is vital as it recognizes the extra value provided by hitters who can advance more bases per hit, contributing significantly more to their teams' scoring opportunities.
OPS, which stands for On-base Plus Slugging, provides a more comprehensive assessment of a player's performance compared to batting average. While batting average solely accounts for hits, OPS includes on-base percentage and slugging average, evaluating a player's ability to get on base and hit for power. This makes OPS a superior metric for comparing players across different eras and contexts.
OPS has significantly altered player evaluation, affecting everything from scouting reports to contract negotiations. A high OPS is often a prerequisite for lucrative contracts and starting positions, as it indicates not only the ability to avoid making outs but also to drive in runs through powerful hitting.
In strategic terms, OPS helps managers and front offices make informed decisions about lineup construction, determining optimal batting order based on a combination of OBP and SLG to maximize run production.

Historically, players like Alex Rodriguez, Bryce Harper, David Ortiz, and David Davis have led in OPS, a key baseball statistic highlighting on-base and slugging abilities. Notables such as Ross Barnes with an OPS of .879 and David McWater with 1.082 also top the list, excelling due to their consistent power hitting and ability to get on base, distinguishing them as some of the best in baseball history for their standout offensive production and clutch performance.
OPS, primarily an offensive metric, indirectly influences defensive strategies through its insight into a player's hitting abilities. Teams analyze OPS data to predict batting behavior, which can guide the alignment of fielders. For example, a player with a high slugging component in their OPS might prompt an outfield shift towards greater depth to reduce the chances of extra-base hits.
In practical terms, teams use OPS data to configure defensive shifts. A player with a high OPS due to a strong slugging percentage might face a strategic alignment of outfielders playing deeper or infielders shifting to one side if his hits are predominantly to one field.
An OPS of 700 places a player in the top third among Major League Baseball hitters, categorizing them as above average. In fantasy baseball, a 700 OPS can significantly contribute to a team's success. Historically, greats like Mark McGwire, who had a .982 career OPS, demonstrate that while a 700 OPS is good falling between "good" and "very good" on most scales it isn't quite elite but is still highly respectable.
A good OPS is generally considered to be .800 or above, indicating an effective balance of getting on base and hitting for power. Historically, the elite hitters have managed OPS figures above 1.000, reflecting exceptional offensive skills. This variation in OPS can also be influenced by the characteristics of different baseball stadiums, which affect hitting dynamics.
OPS can vary significantly across different baseball eras and conditions due to changes in pitching strategies, ballpark dimensions, and the baseball itself. For instance, the dead-ball era saw lower OPS figures compared to the live-ball era, which started in the early 1920s.
While OPS is a prevalent metric combining on-base percentage and slugging percentage to assess a player's offensive performance, it's not without limitations. It overlooks elements like sacrifice bunts and is influenced by park factors, which can skew a player's OPS. Alternative statistics like OPS+ and wRC+ provide adjustments for these variables, offering a possibly more accurate measure of a player's performance.
Players like Babe Ruth and Ted Williams, with career OPS of 1.164 and 1.116, respectively, demonstrate the impact of high OPS scores. Their ability to drive in runs and generate offensive opportunities made them central figures in their team's strategies. Their exceptional performances also highlight how baseball's scoring system rewards players who excel in both getting on base and hitting for power.
Comparing players like Hank Aaron and Mike Trout helps illustrate the consistency of OPS across eras. Despite the different contexts they played in, both showed consistently high OPS, confirming the metric's reliability in evaluating player performance.
While OPS is a valuable metric, it does not account for base-running skills or defensive performance. It can also be skewed by ballpark factors, where players in hitter-friendly parks might have inflated OPS.
OPS+ and wRC+ are refined versions of OPS that adjust for ballpark effects and the overall offensive environment, providing a more accurate measure of a player's performance relative to their peers.
