0.9σ gap
wOBA-against (actual)0.342
xwOBA-against (deserved)0.321

Valdez’s wOBA-against sits at 0.342, but the quality of contact underneath says it should be 0.321 — a gap of 0.021, 0.9 standard deviations from the MLB norm over 184 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
