Unlucky so far. Better days ahead.

0.3σ gap
wOBA-against (actual)0.332
xwOBA-against (deserved)0.325

Gusto’s wOBA-against sits at 0.332, but the quality of contact underneath says it should be 0.325 — a gap of 0.008, 0.3 standard deviations from the MLB norm over 67 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
