0.9σ gap
wOBA-against (actual)0.373
xwOBA-against (deserved)0.346

Feltner’s wOBA-against sits at 0.373, but the quality of contact underneath says it should be 0.346 — a gap of 0.027, 0.9 standard deviations from the MLB norm over 70 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
