Running hot. Expect some cooling.

-0.2σ gap
wOBA-against (actual)0.338
xwOBA-against (deserved)0.345

Sears’s wOBA-against sits at 0.338, but the quality of contact underneath says it should be 0.345 — a gap of 0.007, -0.2 standard deviations from the MLB norm over 33 IP. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
