2.4σ gap
wOBA-against (actual)0.446
xwOBA-against (deserved)0.370

Agnos’s wOBA-against sits at 0.446, but the quality of contact underneath says it should be 0.370 — a gap of 0.076, 2.4 standard deviations from the MLB norm over 46 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
