==An OPS scale==
[[Bill James]], in his essay titled "The 96 Families of Hitters"<ref>James, Bill. ''The 96 Families of Hitters''. <u>The Bill James Gold Mine</u>, 2009, p.24.</ref> uses seven different categories for classification by OPS:

{| class="wikitable"
|-
! Category !! Classification !! OPS range
|-
| A || Great || .9000 and higher
|-
| B || Very good || .8334 to .8999
|-
| C || Above average || .7667 to .8333
|-
| D || Average || .7000 to .7666
|-
| E || Below average || .6334 to .6999
|-
| F || Poor || .5667 to .6333
|-
| G || Very poor || .5666 and lower
|}

This effectively transforms OPS into a seven-point ordinal scale. Substituting quality labels such as ''excellent'' (A), ''very good'' (B), ''good'' (C), ''average'' (D), ''fair'' (E), ''poor'' (F) and ''very poor'' (G) for the A–G categories creates a subjective reference for OPS values.
