0.4σ gap
wOBA-against (actual)0.364
xwOBA-against (deserved)0.352

Ray’s wOBA-against sits at 0.364, but the quality of contact underneath says it should be 0.352 — a gap of 0.013, 0.4 standard deviations from the MLB norm over 82 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
