1.2σ gap
wOBA-against (actual)0.319
xwOBA-against (deserved)0.283

Hoffman’s wOBA-against sits at 0.319, but the quality of contact underneath says it should be 0.283 — a gap of 0.036, 1.2 standard deviations from the MLB norm over 66 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
