Running hot. Expect some cooling.

-2.9σ gap
wOBA (actual)0.377
xwOBA (deserved)0.263

Cox’s wOBA sits at 0.377, but the quality of contact underneath says it should be 0.263 — a gap of 0.114, -2.9 standard deviations from the MLB norm over 109 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
