Unlucky so far. Better days ahead.

1.6σ gap
wOBA-against (actual)0.386
xwOBA-against (deserved)0.326

Kuhnel’s wOBA-against sits at 0.386, but the quality of contact underneath says it should be 0.326 — a gap of 0.060, 1.6 standard deviations from the MLB norm over 31 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
