How to Calculate OPS in Baseball
OPS stands for On-Base Plus Slugging. It combines two important hitting skills: reaching base and hitting for power.
For parents and players, OPS is useful because it shows more than batting average alone. A hitter who walks often and hits extra-base hits can be valuable even if batting average is not the highest on the team.

Formula
OPS = OBP + SLG.
OBP
On-base percentage measures how often a player reaches base by hit, walk, or hit-by-pitch.
SLG
Slugging percentage measures total bases per at-bat.
Example
If a player has a .380 OBP and a .470 SLG, OPS is .850.
How to calculate OBP
Basic formula
OBP = (H + BB + HBP) ÷ (AB + BB + HBP + SF).
What it shows
OBP rewards players who avoid outs and reach base safely.
Why parents should track it
Youth players who walk, control the strike zone, and avoid chasing bad pitches may show value through OBP.
Common mistake
Do not use at-bats alone for OBP. Walks and hit-by-pitches are included.
How to calculate SLG
Total bases
Singles count as 1, doubles as 2, triples as 3, and home runs as 4.
Formula
SLG = Total Bases ÷ At-Bats.
Example
A player with 10 total bases in 20 at-bats has a .500 slugging percentage.
What it shows
SLG rewards extra-base hits and power production.
Why OPS is useful
Balanced view
OPS combines plate discipline and power.
Better than AVG alone
A hitter with fewer singles but more walks and extra-base hits may have a stronger OPS.
Season tracking
OPS is especially useful across a full season or tournament set.
Development context
Use OPS with strikeout rate, walk rate, and quality at-bats for a better picture.
Frequently asked questions
What does OPS mean in baseball?
OPS means on-base plus slugging. It combines how often a player reaches base and how much power the player produces.
Is OPS hard to calculate manually?
It can be time-consuming because you must calculate OBP and SLG first. A stats tracker app can do it automatically.
Is OPS useful for youth baseball?
Yes, especially when parents and coaches want to see more than batting average.
Can a player have a high OPS with a low batting average?
Yes. Walks and extra-base hits can raise OPS even when batting average is not high.
