1.4σ gap
wOBA-against (actual)0.335
xwOBA-against (deserved)0.301

Alcantara’s wOBA-against sits at 0.335, but the quality of contact underneath says it should be 0.301 — a gap of 0.035, 1.4 standard deviations from the MLB norm over 136 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
