Running hot. Expect some cooling.

-1.0σ gap
wOBA-against (actual)0.317
xwOBA-against (deserved)0.354

Milner’s wOBA-against sits at 0.317, but the quality of contact underneath says it should be 0.354 — a gap of 0.036, -1.0 standard deviations from the MLB norm over 32 IP. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
