Unlucky so far. Better days ahead.

0.8σ gap
wOBA-against (actual)0.351
xwOBA-against (deserved)0.330

Fedde’s wOBA-against sits at 0.351, but the quality of contact underneath says it should be 0.330 — a gap of 0.020, 0.8 standard deviations from the MLB norm over 130 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
