Running hot. Expect some cooling.

-1.1σ gap
wOBA-against (actual)0.265
xwOBA-against (deserved)0.303

Junis’s wOBA-against sits at 0.265, but the quality of contact underneath says it should be 0.303 — a gap of 0.038, -1.1 standard deviations from the MLB norm over 36 IP. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
