Frequently Asked Questions

What does OPS stand for in baseball?

OPS stands for On-Base Plus Slugging. It combines a batter's On-Base Percentage (OBP) — how often they reach base — and Slugging Percentage (SLG) — how many total bases they record per at-bat — into a single number that reflects overall offensive performance.

How do you calculate OPS?

OPS = OBP + SLG. On-Base Percentage is (H + BB + HBP) ÷ (AB + BB + HBP + SF). Slugging Percentage is Total Bases ÷ AB, where Total Bases = singles + (2 × doubles) + (3 × triples) + (4 × home runs). Add the two values together to get OPS.

What is a good OPS in baseball?

A good OPS is generally considered .800 or above at the MLB level. Elite hitters often post OPS above .900, while an OPS over 1.000 is exceptional. Values between .700 and .800 are considered average, and anything below .700 is below average for a major league hitter.

Is OPS better than batting average for evaluating hitters?

Most sabermetricians consider OPS a more complete measure than batting average because it accounts for both how often a player reaches base (including walks) and the power of their hits. Batting average only counts the rate of hits per at-bat and treats all hits equally, missing important offensive contributions.

Does OPS include walks?

Yes — walks (BB) and hit-by-pitches (HBP) are included in the On-Base Percentage component of OPS. They are counted in the numerator alongside hits and appear in the denominator as well, giving credit to batters who draw walks even without recording a hit.

Can OPS exceed 1.000?

Yes, OPS can exceed 1.000 because it is the sum of two separate percentages rather than a single rate. An OPS above 1.000 represents truly elite offensive production. Shohei Ohtani posted a 1.036 OPS in 2024, placing him among the game's all-time greats.

What is the difference between OBP and SLG?

OBP (On-Base Percentage) measures how frequently a batter reaches base by any means — hits, walks, or hit-by-pitches. SLG (Slugging Percentage) measures the average number of bases earned per at-bat, giving extra weight to extra-base hits. OBP rewards plate discipline; SLG rewards power hitting.

What is OPS+ and how is it different from OPS?

OPS+ is a park- and league-adjusted version of OPS, scaled so that 100 represents a league-average hitter. An OPS+ of 150 means the player performed 50% better than league average after adjusting for ballpark effects. Raw OPS does not account for era or ballpark, making OPS+ more useful for cross-era comparisons.
