0.8σ gap
wOBA-against (actual)0.354
xwOBA-against (deserved)0.335

Manaea’s wOBA-against sits at 0.354, but the quality of contact underneath says it should be 0.335 — a gap of 0.019, 0.8 standard deviations from the MLB norm over 147 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
