What is a good OPS in baseball?

In MLB, an OPS above .900 is elite, .800–.900 is above average, .700–.800 is average, and below .700 is below average. The all-time single-season record is Babe Ruth's 1.3791 in 1920.

What counts as a plate appearance vs. an at-bat?

A plate appearance is any trip to the plate. An at-bat excludes walks, hit-by-pitches, sacrifice flies, and sacrifice bunts. OBP uses plate appearances in the denominator; SLG uses only at-bats.

How are singles calculated?

Singles = Total Hits − Doubles − Triples − Home Runs. The calculator derives this automatically once you enter all hit types.

What is OPS+ and how is it different?

OPS+ adjusts raw OPS for the ballpark and era, setting 100 as league average. This calculator computes raw OPS, which is useful for quick comparisons without the adjustment factor.

Does OPS account for stolen bases or defense?

No. OPS is a purely offensive batting metric. It does not include stolen bases, caught stealing, or any defensive statistics. Stats like WAR incorporate those additional factors.

Summary

Enter your batter's plate stats to instantly compute OBP, SLG, and OPS with quality tier ratings.

How it works

Enter at-bats, hits, doubles, triples, and home runs for the batter.
Enter walks (BB), hit-by-pitches (HBP), and sacrifice flies (SF).
On-base Percentage (OBP) = (H + BB + HBP) ÷ (AB + BB + HBP + SF).
Slugging Percentage (SLG) = Total Bases ÷ AB, where TB = 1×singles + 2×doubles + 3×triples + 4×HR.
OPS = OBP + SLG. Results are color-coded by MLB quality tier.
