0.0σ gap
wOBA-against (actual)0.348
xwOBA-against (deserved)0.346

Pérez’s wOBA-against sits at 0.348, but the quality of contact underneath says it should be 0.346 — a gap of 0.001, 0.0 standard deviations from the MLB norm over 44 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
