Running hot. Expect some cooling.

-1.4σ gap
wOBA (actual)0.384
xwOBA (deserved)0.344

Jeffers’s wOBA sits at 0.384, but the quality of contact underneath says it should be 0.344 — a gap of 0.040, -1.4 standard deviations from the MLB norm over 388 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
