1.7σ gap
wOBA-against (actual)0.370
xwOBA-against (deserved)0.314

Medina’s wOBA-against sits at 0.370, but the quality of contact underneath says it should be 0.314 — a gap of 0.056, 1.7 standard deviations from the MLB norm over 45 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
