Unlucky so far. Better days ahead.

1.3σ gap
wOBA-against (actual)0.379
xwOBA-against (deserved)0.332

Englert’s wOBA-against sits at 0.379, but the quality of contact underneath says it should be 0.332 — a gap of 0.047, 1.3 standard deviations from the MLB norm over 32 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
