-4.5σ gap
wOBA (actual)0.512
xwOBA (deserved)0.344

Donovan’s wOBA sits at 0.512, but the quality of contact underneath says it should be 0.344 — a gap of 0.168, -4.5 standard deviations from the MLB norm over 127 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
