1.4σ gap
wOBA-against (actual)0.339
xwOBA-against (deserved)0.295

Hoffman’s wOBA-against sits at 0.339, but the quality of contact underneath says it should be 0.295 — a gap of 0.044, 1.4 standard deviations from the MLB norm over 57 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
