Unlucky so far. Better days ahead.

0.5σ gap
wOBA (actual)0.232
xwOBA (deserved)0.249

Refsnyder’s wOBA sits at 0.232, but the quality of contact underneath says it should be 0.249 — a gap of 0.017, 0.5 standard deviations from the MLB norm over 136 PA. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
