Unlucky so far. Better days ahead.

1.2σ gap
wOBA-against (actual)0.375
xwOBA-against (deserved)0.342

Mikolas’s wOBA-against sits at 0.375, but the quality of contact underneath says it should be 0.342 — a gap of 0.033, 1.2 standard deviations from the MLB norm over 98 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
