Unlucky so far. Better days ahead.

0.7σ gap
wOBA-against (actual)0.278
xwOBA-against (deserved)0.256

Latz’s wOBA-against sits at 0.278, but the quality of contact underneath says it should be 0.256 — a gap of 0.022, 0.7 standard deviations from the MLB norm over 74 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
