Regression watch

Running hot. Expect some cooling.

-1.2σ gap
wOBA (actual)0.338
xwOBA (deserved)0.300

Williamson’s wOBA sits at 0.338, but the quality of contact underneath says it should be 0.300 — a gap of 0.038, -1.2 standard deviations from the MLB norm over 239 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
