0.9σ gap
wOBA-against (actual)0.327
xwOBA-against (deserved)0.301

Suarez’s wOBA-against sits at 0.327, but the quality of contact underneath says it should be 0.301 — a gap of 0.027, 0.9 standard deviations from the MLB norm over 68 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
