1.3σ gap
wOBA-against (actual)0.340
xwOBA-against (deserved)0.303

Medina’s wOBA-against sits at 0.340, but the quality of contact underneath says it should be 0.303 — a gap of 0.037, 1.3 standard deviations from the MLB norm over 75 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
