-0.8σ gap
wOBA (actual)0.368
xwOBA (deserved)0.345

Herrera’s wOBA sits at 0.368, but the quality of contact underneath says it should be 0.345 — a gap of 0.022, -0.8 standard deviations from the MLB norm over 431 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
