0.8σ gap
wOBA-against (actual)0.331
xwOBA-against (deserved)0.312

Ginn’s wOBA-against sits at 0.331, but the quality of contact underneath says it should be 0.312 — a gap of 0.019, 0.8 standard deviations from the MLB norm over 140 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
