2.3σ gap
wOBA-against (actual)0.384
xwOBA-against (deserved)0.307

Basso’s wOBA-against sits at 0.384, but the quality of contact underneath says it should be 0.307 — a gap of 0.076, 2.3 standard deviations from the MLB norm over 43 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
