0.3σ gap
wOBA-against (actual)0.318
xwOBA-against (deserved)0.311

Webb’s wOBA-against sits at 0.318, but the quality of contact underneath says it should be 0.311 — a gap of 0.007, 0.3 standard deviations from the MLB norm over 163 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
