0.7σ gap
wOBA-against (actual)0.306
xwOBA-against (deserved)0.287

Detmers’s wOBA-against sits at 0.306, but the quality of contact underneath says it should be 0.287 — a gap of 0.020, 0.7 standard deviations from the MLB norm over 111 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
