0.7σ gap
wOBA-against (actual)0.324
xwOBA-against (deserved)0.300

Hentges’s wOBA-against sits at 0.324, but the quality of contact underneath says it should be 0.300 — a gap of 0.023, 0.7 standard deviations from the MLB norm over 32 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
