Unlucky so far. Better days ahead.

1.6σ gap
wOBA (actual)0.237
xwOBA (deserved)0.287

Hayes’s wOBA sits at 0.237, but the quality of contact underneath says it should be 0.287 — a gap of 0.050, 1.6 standard deviations from the MLB norm over 260 PA. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
