0.0σ gap
wOBA-against (actual)0.307
xwOBA-against (deserved)0.306

Cornelio’s wOBA-against sits at 0.307, but the quality of contact underneath says it should be 0.306 — a gap of 0.001, 0.0 standard deviations from the MLB norm over 35 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
