Understanding the Inputs
Key metrics for calculating OPS
On-Base Components
Metrics that contribute to OBP (On-Base Percentage).
Hits (H): Reaching base via hit.
Walks (BB): Reaching via base on balls.
Hit By Pitch (HBP): Reaching via HBP.
Slugging Components
Metrics that contribute to SLG (Slugging Percentage).
Total Bases: Sum of base values of all hits.
Extra Base Hits: 2B, 3B, HR significantly boost this.
Formula Used
OPS = OBP + SLG
OBP = (H + BB + HBP) / (AB + BB + HBP + SF)
SLG = (1B + 2×2B + 3×3B + 4×HR) / AB
OPS is simply the sum of a player's On-base Percentage and Slugging Percentage. It solves the issue of Batting Average ignoring walks and Slugging Percentage ignoring walks (and OBP ignoring power).
For decades, Batting Average was King. Then, the "Moneyball" revolution showed us On-Base Percentage. Now, OPS (On-Base Plus Slugging) stands as the single most comprehensive quick metric for offensive value.
OPS (On-base Plus Slugging) is exactly what it sounds like: the sum of a player's On-Base Percentage (OBP) and Slugging Percentage (SLG).
OPS = OBP + SLG
It was designed to answer a simple question: "How well does this player get on base, and how much power do they have when they hit?" By combining these two metrics, OPS gives a complete picture of a hitter's ability to create runs.
Why OPS Works So Well
Traditional stats have blind spots:
Batting Average ignores walks and treats a single the same as a home run.
Home Runs ignore consistency and ability to get on base.
RBIs are dependent on teammates getting on base ahead of you.
OPS fixes this. It values the ability to not make an out (OBP) and the ability to hit for extra bases (SLG). It correlates extremely well with Runs Scored, which is the ultimate goal of an offense.
Benchmarks: What is a "Good" OPS?
OPS scales differently than average. Here is the general hierarchy for MLB players:
Major League Baseball (MLB)
1.000+: MVP Level. A rare season (e.g., Bryce Harper, Shohei Ohtani).
.900+: Elite. An All-Star starter.
.800+: Above Average. A strong offensive contributor.
.700 - .750: Average. The baseline for a regular starter.
Below .650: Poor. Hard to justify a spot in the lineup without elite defense.
Positional Adjustments
Expectations vary by position. A First Baseman or Designated Hitter is expected to have an OPS over .800. A Shortstop or Catcher might be valuable with an OPS of .700 because of their defensive importance.
How to Improve Your OPS
1. Improve OBP (The Easier Path)
Increasing your slugging percentage usually requires mechanical changes or strength training. Increasing OBP can often be done by improving plate discipline—swinging at fewer bad pitches and taking more walks.
2. Drive the Ball (SLG)
To boost the "S" in OPS, you need extra-base hits. This means looking for pitches you can drive, rather than just deflect. It implies an aggressive mindset on strikes (counts like 2-0 or 3-1).
3. Balance
Don't sacrifice one for the other. Swinging for the fences might raise SLG but tank your OBP if you strike out too much. Taking too many strikes might raise OBP but leave your SLG low. finding the balance is key.
Limitations of OPS
While excellent, OPS is not perfect:
Undervalues OBP: Statistically, a point of OBP is worth about 1.8x more than a point of SLG in terms of run creation. OPS treats them as equal (1 + 1). This is why saber-metricians prefer wOBA (Weighted On-Base Average).
Park Factors: An .800 OPS at Coors Field (hitter friendly) is less impressive than an .800 OPS at Petco Park (pitcher friendly). OPS+ (OPS Plus) adjusts for this.
Frequently Asked Questions
Common questions about OPS
What is a perfect OPS?
Technically, the maximum possible OPS is 5.000 (1.000 OBP + 4.000 SLG), achievable if a player hits a Home Run in every single at-bat. In reality, anything over 1.000 is spectacular.
Is OPS better than Batting Average?
Yes. OPS correlates much more strongly with run scoring than Batting Average does. A team of .250 hitters with high OPS will outscore a team of .280 hitters with low OPS.
What is OPS+?
OPS+ is a normalized version of OPS where 100 is the league average. It adjusts for park factors (stadium dimensions, altitude). An OPS+ of 150 means the player is 50% better than the league average.
Does speed affect OPS?
Indirectly. Speed can turn singles into doubles (increasing SLG) or help beat out infield hits (increasing OBP). However, OPS does not directly measure stolen bases.
