1.3σ gap
wOBA-against (actual)0.359
xwOBA-against (deserved)0.325

Warren’s wOBA-against sits at 0.359, but the quality of contact underneath says it should be 0.325 — a gap of 0.035, 1.3 standard deviations from the MLB norm over 106 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
