Regression watch

Running hot. Expect some cooling.

-0.3σ gap
wOBA-against (actual)0.253
xwOBA-against (deserved)0.264

Weaver’s wOBA-against sits at 0.253, but the quality of contact underneath says it should be 0.264 — a gap of 0.011, -0.3 standard deviations from the MLB norm over 42 IP. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
