0.2σ gap
wOBA-against (actual)0.279
xwOBA-against (deserved)0.274

Okert’s wOBA-against sits at 0.279, but the quality of contact underneath says it should be 0.274 — a gap of 0.005, 0.2 standard deviations from the MLB norm over 70 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
