Unlucky so far. Better days ahead.

0.9σ gap
wOBA-against (actual)0.321
xwOBA-against (deserved)0.294

Ginkel’s wOBA-against sits at 0.321, but the quality of contact underneath says it should be 0.294 — a gap of 0.027, 0.9 standard deviations from the MLB norm over 69 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
