Running hot. Expect some cooling.

-2.5σ gap
wOBA (actual)0.412
xwOBA (deserved)0.338

Vaughn’s wOBA sits at 0.412, but the quality of contact underneath says it should be 0.338 — a gap of 0.074, -2.5 standard deviations from the MLB norm over 314 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
