1.6σ gap
wOBA-against (actual)0.360
xwOBA-against (deserved)0.313

Medina’s wOBA-against sits at 0.360, but the quality of contact underneath says it should be 0.313 — a gap of 0.047, 1.6 standard deviations from the MLB norm over 64 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
