1.1σ gap
wOBA-against (actual)0.344
xwOBA-against (deserved)0.308

Kittredge’s wOBA-against sits at 0.344, but the quality of contact underneath says it should be 0.308 — a gap of 0.036, 1.1 standard deviations from the MLB norm over 48 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
