2.7σ gap
wOBA-against (actual)0.368
xwOBA-against (deserved)0.276

Yarbrough’s wOBA-against sits at 0.368, but the quality of contact underneath says it should be 0.276 — a gap of 0.092, 2.7 standard deviations from the MLB norm over 41 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
