OPS

OPS

On-base percentage plus slugging percentage; a single number for overall offensive value.

OPS is on-base percentage plus slugging percentage. It combines getting on base (OBP) with hitting for power (SLG) into one number, which is why it has become the quick-glance measure of a complete hitter.

Slugging percentage, the second half, is total bases divided by at-bats, so a double is worth twice a single and a home run four times. Adding it to OBP rewards both patience and power in a single figure.

An OPS around .800 is good and .900-plus is excellent at most levels. It's an imperfect sum (OBP and SLG have different denominators), but it's a fast, useful snapshot.

How is OPS calculated?

Add on-base percentage and slugging percentage together. OBP measures how often a hitter reaches base; SLG measures total bases per at-bat.

What is a good OPS?

At most levels, an OPS near .800 is good and .900 or above is excellent.
