1.0σ gap
wOBA-against (actual)0.336
xwOBA-against (deserved)0.300

Muñoz’s wOBA-against sits at 0.336, but the quality of contact underneath says it should be 0.300 — a gap of 0.036, 1.0 standard deviations from the MLB norm over 37 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
