1.7σ gap
wOBA-against (actual)0.340
xwOBA-against (deserved)0.296

Burke’s wOBA-against sits at 0.340, but the quality of contact underneath says it should be 0.296 — a gap of 0.044, 1.7 standard deviations from the MLB norm over 113 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
