What the "Plus" Means
The plus sign in wRC+ follows the same convention as OPS+ and ERA+. It signals two things happened to the raw number: it was park-adjusted and scaled to 100 as the league-average baseline. That scaling is what makes wRC+ useful across eras. A wRC+ of 130 means the same thing in 2026 as it did in 1996: the hitter was 30% better than their peers. No mental math required.
What wRC+ Actually Measures
The foundation is wOBA (Weighted On-Base Average), which assigns each offensive outcome a run value based on historical play-by-play data. A home run is worth more than a triple, a triple more than a double, each weighted by how many runs that event actually produces on average. wRC takes that wOBA, converts it into runs using a park-adjusted scaling factor, and produces a raw runs-created total. The "plus" version normalizes that to 100.
Where wRC = ( wOBA / wOBA Scale + lgR/PA − BPF × lgR/PA ) × PA
What Is a Good wRC+ in Baseball?
Because 100 is always league average by definition, the scale is intuitive:
| wRC+ | Grade | What it looks like |
|---|---|---|
| 160+ | MVP-caliber | Judge, Trout peak seasons |
| 140–159 | All-Star, elite | Top 10–15 hitters in MLB |
| 120–139 | Above average | Solid middle-of-order bat |
| 110–119 | Above average | Productive everyday player |
| 95–109 | Average | League median range |
| 80–94 | Below average | Acceptable with elite defense |
| <80 | Poor | Bench/platoon territory |
wRC+ vs. OPS+: What's the Difference?
Both are park-adjusted, scaled to 100. The difference is methodology. OPS+ treats on-base percentage and slugging as equal halves, which overweights slugging. wRC+ uses linear weights derived from actual run values, so every event is calibrated to what it produces. In most analytical contexts, wRC+ is the preferred number.
wRC+ vs. Batting Average: Why This Matters More
Batting average ignores walks, ignores extra-base hits beyond their binary value, and gives no credit for how hard a ball was hit. Two hitters can post .280 and have wildly different offensive values. A player hitting .240 with a .370 OBP and 25 home runs might carry a wRC+ of 135. A player hitting .290 with a .320 OBP and 8 home runs might sit at 105. Batting average inverts that picture. wRC+ gets it right.
How wRC+ Is Used in Prospect Evaluation
At the minor league level, wRC+ requires extra caution. MiLB run environments vary more dramatically than the majors, and park factors are less reliable with smaller sample sizes. Age-relative wRC+ is particularly useful in prospect work. A 22-year-old posting 130 wRC+ in Triple-A is a very different signal than a 27-year-old doing the same thing.
