0.5σ gap
wOBA-against (actual)0.287
xwOBA-against (deserved)0.275

Rasmussen’s wOBA-against sits at 0.287, but the quality of contact underneath says it should be 0.275 — a gap of 0.012, 0.5 standard deviations from the MLB norm over 149 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
