1.9σ gap
wOBA-against (actual)0.337
xwOBA-against (deserved)0.273

Fluharty’s wOBA-against sits at 0.337, but the quality of contact underneath says it should be 0.273 — a gap of 0.064, 1.9 standard deviations from the MLB norm over 39 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
