Unlucky so far. Better days ahead.

1.2σ gap
wOBA-against (actual)0.261
xwOBA-against (deserved)0.221

Duran’s wOBA-against sits at 0.261, but the quality of contact underneath says it should be 0.221 — a gap of 0.039, 1.2 standard deviations from the MLB norm over 53 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
