0.6σ gap
wOBA-against (actual)0.326
xwOBA-against (deserved)0.307

Dobbins’s wOBA-against sits at 0.326, but the quality of contact underneath says it should be 0.307 — a gap of 0.019, 0.6 standard deviations from the MLB norm over 54 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
