3.2σ gap
wOBA-against (actual)0.455
xwOBA-against (deserved)0.345

Crochet’s wOBA-against sits at 0.455, but the quality of contact underneath says it should be 0.345 — a gap of 0.110, 3.2 standard deviations from the MLB norm over 35 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
