Running hot. Expect some cooling.

-0.2σ gap
wOBA (actual)0.267
xwOBA (deserved)0.260

Castillo’s wOBA sits at 0.267, but the quality of contact underneath says it should be 0.260 — a gap of 0.007, -0.2 standard deviations from the MLB norm over 192 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
