1.4σ gap
wOBA-against (actual)0.360
xwOBA-against (deserved)0.326

Warren’s wOBA-against sits at 0.360, but the quality of contact underneath says it should be 0.326 — a gap of 0.034, 1.4 standard deviations from the MLB norm over 142 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
