Unlucky so far. Better days ahead.

1.0σ gap
wOBA-against (actual)0.359
xwOBA-against (deserved)0.333

Cecconi’s wOBA-against sits at 0.359, but the quality of contact underneath says it should be 0.333 — a gap of 0.026, 1.0 standard deviations from the MLB norm over 123 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
