Running hot. Expect some cooling.

-2.7σ gap
wOBA (actual)0.405
xwOBA (deserved)0.329

Vaughn’s wOBA sits at 0.405, but the quality of contact underneath says it should be 0.329 — a gap of 0.076, -2.7 standard deviations from the MLB norm over 354 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
