1.1σ gap
wOBA-against (actual)0.366
xwOBA-against (deserved)0.338

Bassitt’s wOBA-against sits at 0.366, but the quality of contact underneath says it should be 0.338 — a gap of 0.028, 1.1 standard deviations from the MLB norm over 107 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
