Calculate OPS (OBP + SLG) - the best single offensive stat
What is OPS?
OPS (On-Base Plus Slugging) combines on-base percentage and slugging percentage into one number. Many analysts consider OPS the best single statistic for measuring overall offensive value because it captures both getting on base and hitting for power.
Higher is better! An OPS of .800 means you're an above-average offensive player. An OPS of .900+ makes you elite at most levels.

What is a Good OPS?
| Level | Elite (MVP) | Excellent | Above Average | Average |
|---|---|---|---|---|
| MLB | .900+ | .800-.899 | .750-.799 | .700-.749 |
| College (D1) | .950+ | .850-.949 | .775-.849 | .725-.774 |
| High School | 1.000+ | .850-.999 | .750-.849 | .650-.749 |
| Youth (9-12) | 1.100+ | .900-1.099 | .700-.899 | .600-.699 |
Rule of Thumb: An .800 OPS is excellent at nearly every level. An .900 OPS makes you elite. A 1.000 OPS is MVP territory.
Why OPS is the Best Single Offensive Stat
OPS (On-Base Plus Slugging) has become the go-to statistic for evaluating offensive performance because it combines the two most important offensive skills: getting on base and hitting for power. While no single stat tells the complete story, OPS comes closest to measuring overall offensive value.
The OPS Formula
It's that simple! Add your on-base percentage and slugging percentage together. The result typically falls between .600 (poor) and 1.000+ (elite).
OPS vs Other Stats
Why OPS Beats Batting Average
Batting average ignores walks and treats all hits equally. OPS values both plate discipline (OBP component) and power (SLG component), giving a much more complete picture of offensive contribution.
OPS vs wOBA
wOBA (Weighted On-Base Average) is technically more accurate because it properly weights each outcome by its actual run value. However, OPS is easier to calculate and understand, and the two correlate very highly (r = .95+).
Famous OPS Seasons
- Babe Ruth (1920): 1.379 OPS - highest in MLB history
- Barry Bonds (2004): 1.422 OPS - modern era record
- Shohei Ohtani (2023): 1.066 OPS - elite modern performance
- Aaron Judge (2022): 1.111 OPS - 62 home run season
How to Improve Your OPS
Improve OBP Component:
- Work counts and draw more walks
- Improve pitch recognition
- Don't chase pitches outside the zone
Improve SLG Component:
- Develop bat speed and strength
- Optimize launch angle for fly balls
- Look for pitches to drive
Frequently Asked Questions About OPS
What is a good OPS in baseball?
In MLB, an .800 OPS is very good, .900 is excellent, and 1.000+ is elite MVP-level production. The league average is typically around .720-.740.
Can OPS be higher than 2.000?
Theoretically yes, but it's never happened. Babe Ruth's 1.379 and Barry Bonds' 1.422 are the highest ever. A 2.000 OPS would require a 1.000 OBP and 1.000 SLG, which is essentially impossible.
Is OPS a perfect stat?
No stat is perfect. OPS doesn't account for baserunning, defense, or park factors. It also weights OBP and SLG equally when OBP is actually slightly more valuable. Despite these limitations, it's still an excellent quick measure of offensive value.
