Unlucky so far. Better days ahead.

1.3σ gap
wOBA-against (actual)0.338
xwOBA-against (deserved)0.292

Mayza’s wOBA-against sits at 0.338, but the quality of contact underneath says it should be 0.292 — a gap of 0.046, 1.3 standard deviations from the MLB norm over 34 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
