3.2σ gap
wOBA-against (actual)0.441
xwOBA-against (deserved)0.340

Gordon’s wOBA-against sits at 0.441, but the quality of contact underneath says it should be 0.340 — a gap of 0.101, 3.2 standard deviations from the MLB norm over 54 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
