0.6σ gap
wOBA-against (actual)0.372
xwOBA-against (deserved)0.355

Corbin’s wOBA-against sits at 0.372, but the quality of contact underneath says it should be 0.355 — a gap of 0.017, 0.6 standard deviations from the MLB norm over 78 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
