1.5σ gap
wOBA-against (actual)0.363
xwOBA-against (deserved)0.324

Weathers’s wOBA-against sits at 0.363, but the quality of contact underneath says it should be 0.324 — a gap of 0.039, 1.5 standard deviations from the MLB norm over 104 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
