Each outcome is fit as logit P = μ + βbatter + πpitcher across every plate appearance in the season, so hitter and pitcher skill are solved together rather than one being assumed. The adjusted column is this player against a league-average opponent; the run value is that rate priced by its wOBA weight (a walk is worth .690 runs, a home run 2.015), and those values sum to the adjusted wOBA above.
| Outcome | Actual | Adjusted | League | Run value | Regressed, PA |
|---|---|---|---|---|---|
| Walk / HBP | 7.1% | 9.0% | 9.2% | 0.0618 | 181 |
| Strikeout | 3.6% | 19.2% | 22.8% | 0.0000 | 86 |
| Single | 17.9% | 14.2% | 14.1% | 0.1247 | 467 |
| Double | 0.0% | 4.1% | 4.2% | 0.0515 | 1332 |
| Triple | 0.0% | 0.3% | 0.3% | 0.0043 | 922 |
| Home run | 7.1% | 2.9% |
Regressed is how many plate appearances of league-average performance are blended in before a rate is believed — estimated from the spread of the league itself, not chosen. Strikeout rate separates hitters quickly and is barely touched; doubles are mostly noise and are pulled hard toward average. It is why a hot 30-PA cameo does not top this list.
The opponent effect is usually small over a full season, and that is a finding rather than a shortcoming: individual pitchers differ enormously (wOBA allowed spans roughly .263 to .342), but across hundreds of plate appearances almost everyone faces a near-representative sample. The adjustment moves part-time players far more than regulars.

Aggregated from the per-game rows, so a season total always equals the sum of the games behind it. Seasons before the coverage window are absent rather than partial.
