1.1σ gap
wOBA-against (actual)0.311
xwOBA-against (deserved)0.274

Dion’s wOBA-against sits at 0.311, but the quality of contact underneath says it should be 0.274 — a gap of 0.037, 1.1 standard deviations from the MLB norm over 36 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
