1.4σ gap
wOBA-against (actual)0.357
xwOBA-against (deserved)0.317

Mahle’s wOBA-against sits at 0.357, but the quality of contact underneath says it should be 0.317 — a gap of 0.040, 1.4 standard deviations from the MLB norm over 80 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
