Unlucky so far. Better days ahead.

1.5σ gap
wOBA-against (actual)0.360
xwOBA-against (deserved)0.320

Civale’s wOBA-against sits at 0.360, but the quality of contact underneath says it should be 0.320 — a gap of 0.040, 1.5 standard deviations from the MLB norm over 115 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
