Unlucky so far. Better days ahead.

2.2σ gap
wOBA-against (actual)0.419
xwOBA-against (deserved)0.348

Senga’s wOBA-against sits at 0.419, but the quality of contact underneath says it should be 0.348 — a gap of 0.071, 2.2 standard deviations from the MLB norm over 43 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
