wOBA (Weighted On-Base Average) fixes a flaw in OPS: not every event is worth the same. Instead of adding on-base and power in equal parts, wOBA assigns each play —a walk, a single, a double, a home run— the exact value it has in terms of runs.
How do you read it?
It’s expressed on a scale similar to OBP, so it’s easy to read: it sits around .320 for an average hitter and climbs from there.
| wOBA | Level |
|---|---|
| .400 or more | Elite |
| .350 – .399 | Very good |
| .320 | Average |
| Below .300 | Below average |

wOBA is the foundation that wRC+ is built on. It’s sabermetrics’ answer to the question «how much is each thing a hitter does really worth?».
