-1.9σ gap
wOBA (actual)0.415
xwOBA (deserved)0.360

Jeffers’s wOBA sits at 0.415, but the quality of contact underneath says it should be 0.360 — a gap of 0.055, -1.9 standard deviations from the MLB norm over 319 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
