0.6σ gap
wOBA-against (actual)0.333
xwOBA-against (deserved)0.319

Eovaldi’s wOBA-against sits at 0.333, but the quality of contact underneath says it should be 0.319 — a gap of 0.015, 0.6 standard deviations from the MLB norm over 144 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
