-2.5σ gap
wOBA (actual)0.323
xwOBA (deserved)0.247

Story’s wOBA sits at 0.323, but the quality of contact underneath says it should be 0.247 — a gap of 0.076, -2.5 standard deviations from the MLB norm over 281 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
