1.8σ gap
wOBA-against (actual)0.394
xwOBA-against (deserved)0.333

Mey’s wOBA-against sits at 0.394, but the quality of contact underneath says it should be 0.333 — a gap of 0.061, 1.8 standard deviations from the MLB norm over 36 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
