-0.7σ gap
wOBA (actual)0.338
xwOBA (deserved)0.314

Rooker’s wOBA sits at 0.338, but the quality of contact underneath says it should be 0.314 — a gap of 0.023, -0.7 standard deviations from the MLB norm over 215 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
