Unlucky so far. Better days ahead.

1.5σ gap
wOBA-against (actual)0.390
xwOBA-against (deserved)0.349

Agnos’s wOBA-against sits at 0.390, but the quality of contact underneath says it should be 0.349 — a gap of 0.040, 1.5 standard deviations from the MLB norm over 94 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
