Regression watch

Running hot. Expect some cooling.

-0.2σ gap
wOBA-against (actual)0.276
xwOBA-against (deserved)0.285

Weaver’s wOBA-against sits at 0.276, but the quality of contact underneath says it should be 0.285 — a gap of 0.009, -0.2 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.
