| Quick Answer OPS stands for on-base plus slugging: a hitter’s on-base percentage plus slugging percentage (OPS = OBP + SLG), so a .350 OBP and a .450 SLG make an .800 OPS. In MLB, about .700 to .720 is average, .800 is good, .900 is All-Star level and 1.000 or higher is MVP level. |
If you have been watching your kid’s games or following Major League Baseball lately, you have probably seen OPS flash across a broadcast graphic or stat sheet and wondered what it actually measures. This guide explains how OPS is calculated, what number separates an average hitter from a great one, and why a high batting average can hide an ordinary hitter.
Quick Definition
OPS stands for On Base Plus Slugging. It is exactly what the name says. You take a hitter’s On Base Percentage (OBP), add it to their Slugging Percentage (SLG), and the number you get is their OPS.
In one number, OPS tells you two important things about a hitter at the same time:
- How often does he get on base? That is the OBP part.
- When he hits the ball, how hard does he hit it? That is the SLG part.
That is the whole concept. A hitter with a high OPS gets on base a lot and hits for power. A hitter with a low OPS does neither well. Simple.
If you only remember one sentence from this article, make it this: OPS in baseball explained is the combination of getting on base and hitting for extra bases, expressed as one tidy number.
The Long Answer in Plain Language
Let us unpack the two pieces, because once you see how each is built, OPS will feel obvious.
On Base Percentage (OBP)
OBP measures how often a hitter reaches base safely, whether by a hit, a walk, or being hit by a pitch. The formula looks like this:
OBP = (Hits + Walks + Hit By Pitch) ÷ (At Bats + Walks + Hit By Pitch + Sacrifice Flies)
A good OBP in MLB is around .340. Elite is .400 or higher. The all time leader, Ted Williams, sat at .482, meaning he reached base nearly half the time he came to the plate, which is absurd.
Slugging Percentage (SLG)
SLG measures the power in a hitter’s bat. Instead of counting hits equally, it gives more credit to extra base hits.
SLG = Total Bases ÷ At Bats
A single is worth 1 base, a double 2, a triple 3, a home run 4. Add them up, divide by at bats. A good MLB slugging percentage is around .430. Elite power hitters can push past .600.
Adding Them Up
So when you take OBP plus SLG, you get OPS. A league average hitter typically lands around .720 OPS. In the 2026 MLB regular season, the league as a whole posted a .719 OPS (a .318 OBP and a .400 SLG). The general scale every scout uses goes something like this:
- Below .700: a below average hitter. The lineup is probably better off finding alternatives.
- .700 to .800: a solid, reliable contributor.
- .800 to .900: well above average. The kind of bat a contending team builds around.
- .900 to 1.000: All Star territory.
- Over 1.000: MVP caliber, and at the all time greats level if sustained across a career.
Stats checked October 26, 2026 against MLB’s official 2026 team stats and the FanGraphs rating scales.
What Is a Good OBP?
A good on-base percentage in MLB is about .340, and .390 or higher is excellent. On the FanGraphs rating scale, about .320 is average, .340 is above average and .390 or higher is excellent. The 2026 MLB average was .318, so a hitter at .340 was above the league average that season.
High school baseball has no published national average for on-base percentage, so the fairest comparison is a player against the rest of their own league. A .340 OBP is strong in a league where most hitters sit near .300, and it trails the pack in a league where most hitters reach .400.
Real Examples From the Field
Numbers stick better with examples. Here are a few that show why OPS is so loved by modern coaches.
Example 1: The “Looks Great, Actually Average” Hitter
Player A bats .310 for the season. On the surface, that looks fantastic. But he rarely walks (OBP only .335) and almost never hits for extra bases (SLG .390). His OPS works out to .725, just barely league average. The high batting average masked the fact that he is not really driving runs in.
Example 2: The “Doesn’t Look Great, Actually Elite” Hitter
Player B bats only .255. Old school fans might dismiss him. But he walks a ton (OBP .390), and when he does connect, the ball lands somewhere in the upper deck (SLG .540). His OPS is .930, All Star level. He is quietly one of the most productive hitters in his lineup, even though his batting average is unremarkable.
Example 3: Youth Baseball Reality
In a typical 12U travel team, OPS is not usually tracked formally. But the same logic applies. If a coach is choosing between two players for the 3 hole in the lineup, the kid who walks more and doubles more is almost always the better pick, even if his batting average is lower than the other kid’s. That is the OPS lesson, applied without a calculator. For first year families navigating gear questions alongside stats questions, our Youth Baseball Equipment Checklist covers what every young player should have ready before the first practice.
Why This Matters for Players, Coaches, and Parents
So why has the baseball world fallen in love with OPS over the last twenty years? Three reasons that matter for everyone from MLB front offices down to a Saturday morning rec league game.
1. It captures the full picture of offense. Batting average ignores walks. RBIs depend on the players hitting in front of you. Home runs ignore singles and doubles. OPS folds the most important parts of offense (getting on base and creating extra bases) into one number you can use to compare hitters quickly.
2. It works at every level. The same scale is meaningful in MLB, college, high school, and even competitive youth baseball seasons. The exact league averages shift, but the structure is universal. A player who is well above his league’s average OPS is a player who is helping his baseball team score runs, whether that team wears MLB pinstripes or our own custom Baseball Uniforms and Apparel on a Saturday morning rec diamond.
3. It changes how coaches build lineups. A coach who pays attention to OPS quickly learns that the patient kid who works the count and draws walks is often more valuable than the kid with the prettier swing who chases pitches. That insight shows up in everything from batting orders to who gets the green light to swing freely when ahead in the count.
For parents, the practical takeaway is this. When your child’s youth baseball coach talks about “approach at the plate” (patience, working the count, looking for pitches to drive), the coach is essentially teaching the habits that build a high OPS. Hitting the ball matters, of course. But hitting the right kind of pitches and avoiding outs you do not need to make matters more.
Common Misconceptions Cleared Up
A few things about OPS regularly trip people up, so let us clear them now.
Misconception 1: “OPS and OPS+ are the same thing.”
They are not. OPS+ is a different stat that takes a player’s OPS and adjusts it for the era and ballpark, then rebases it so 100 equals league average. An OPS+ of 150 means the hitter was 50% better than league average that year. If you see a “+”, treat it as a separate, more advanced metric.
Misconception 2: “OPS treats OBP and SLG equally, but it shouldn’t.”
This is a fair critique, and it is why some analysts prefer wOBA (weighted on base average), which gives slightly more weight to OBP because not making outs is the single most valuable thing a hitter can do. OPS is not perfect. It is just a great starting point that is easy to compute and easy to talk about.
Misconception 3: “A high OPS automatically means a great player.”
OPS only measures hitting. A player can have a monster OPS and still be a defensive liability or a poor baserunner. To judge a player as a whole, you need OPS plus defensive metrics plus speed metrics. Do not fall in love with one number.
Misconception 4: “OPS is too modern for youth baseball.”
Many travel and high school teams track OPS in their stat apps, and it gives you a fair way to compare hitters.
Where to Go From Here
If OPS is the first baseball statistic you have learned beyond batting average, it is the right foundation for everything that follows. From here, the next stats worth learning are WHIP (for pitchers), RBI, wOBA, and eventually wRC+, which adjusts everything for context. Once you can read those, a broadcast graphic stops looking like algebra and starts looking like a story.
If you are a player, the path is simpler: walk more, swing at strikes, and look for pitches you can drive. Your OPS will follow. If you are a coach, build practices that reward plate discipline as much as bat speed.
And if you are a parent equipping a youth baseball player or organizing your child’s baseball team for the upcoming baseball season, the same patience that builds a high OPS at the plate is the same patience that builds confident players who stick with the game year after year. Stay with it.

Frequently Asked Questions
What is a good OPS in baseball?
A league average OPS sits around .720. Anything above .800 is well above average. .900 is All Star territory. Over 1.000 is MVP caliber. For youth and high school baseball, the bar is naturally lower, but the same scale logic applies relative to league averages.
How do you calculate OPS in baseball?
Add On Base Percentage (OBP) and Slugging Percentage (SLG) together. OPS = OBP + SLG. Both stats are decimals, so a hitter with a .350 OBP and a .450 SLG has an OPS of .800.
Is OPS better than batting average?
Yes, for evaluating a hitter’s complete offensive contribution. Batting average ignores walks and treats all hits as equal. OPS captures plate discipline (through OBP) and power (through SLG) in a single number you can use to compare players, which is why coaches and front offices rely on it.
Who has the highest OPS of all time in MLB?
Josh Gibson holds the career record at 1.175, since MLB added Negro Leagues statistics (1920 to 1948) to its official record in 2024. Babe Ruth (1.164) and Ted Williams (1.116) follow. For a single season, Gibson’s 1.485 in 1937 is the official record, and Barry Bonds’ 1.421 in 2004 is the modern benchmark. Anything sustained over 1.000 for a full career puts a player in conversation with the all time greats.
Does OPS apply to youth and high school baseball?
Yes. The calculation is identical at every level. Many travel and high school teams track OPS in their stat apps, and it gives you a fair way to compare hitters.
When did OPS become a stat?
Pete Palmer, the statistician who invented OPS, says he had settled on it by 1978. It spread from there, and by 2010 it was printed on baseball cards and used on broadcasts. MLB.com now lists it among its standard stats.
