Unlucky so far. Better days ahead.

1.1σ gap
wOBA-against (actual)0.335
xwOBA-against (deserved)0.308

Cantillo’s wOBA-against sits at 0.335, but the quality of contact underneath says it should be 0.308 — a gap of 0.028, 1.1 standard deviations from the MLB norm over 160 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
