Unlucky so far. Better days ahead.

1.7σ gap
wOBA-against (actual)0.361
xwOBA-against (deserved)0.310

Cruz’s wOBA-against sits at 0.361, but the quality of contact underneath says it should be 0.310 — a gap of 0.051, 1.7 standard deviations from the MLB norm over 60 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
