1.0σ gap
wOBA-against (actual)0.292
xwOBA-against (deserved)0.262

Fluharty’s wOBA-against sits at 0.292, but the quality of contact underneath says it should be 0.262 — a gap of 0.030, 1.0 standard deviations from the MLB norm over 63 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
